Cisco Security Analytics and Logging

Events in Security Cloud Control

This chapter provides information about Security Analytics and Logging (SaaS) in Security Cloud Control.

About Security Analytics and Logging (SaaS) in Security Cloud Control

Terminology Note: In this documentation, when Cisco Security Analytics and Logging (a software as a service product) is used with Security Cloud Control for security event monitoring and analysis, you will see this integration referred to as Cisco Security Analytics and Logging (SaaS) or SAL (SaaS).

Cisco Security Analytics and Logging (SAL) allows you to capture supported types of security events from all of your firewall devices and view them in one place in Security Cloud Control. The events are stored in the Security Analytics and Logging cloud and viewable from the Event Logging page. The Event Logging page allows you to search, filter and analyze the security event data to understand which security rules are being triggered in your network.

Event types in Security Cloud Control

When filtering the security events logged in Secure Logging Analytics (SaaS), you can choose from a list of ASA, FTD, and event types that Security Cloud Control supports. From the Security Cloud Control menu, navigate Analytics > Event Logging and click the filter icon to choose events. These event types represent groups of syslog IDs. The table that follows shows which syslog IDs are included in which event type. To learn more about a specific syslog ID, you can search for it in the Cisco ASA Series Syslog Messages or the Cisco Secure Firewall Threat Defense Syslog Messages guides.

Some syslog events have the additional attribute "EventName." You can filter the events table to find events using the EventName attribute by filtering by attribute:value pairs. See Event Name Attributes for Syslog Events.

Some syslog events will have the additional attributes "EventGroup" and "EventGroupDefinition". You will be able to filter the events table to find events using these additional attributes by filtering by attribute:value pairs. See EventGroup and EventGroupDefinition Attributes for Some Syslog Messages.

The NetFlow events are different from syslog events. The NetFlow filter searches for all NetFlow event IDs that resulted in an NSEL record. Those NetFlow event IDs are defined in the Cisco ASA NetFlow Implementation Guide.

The following table describes the event types that Security Cloud Control supports and lists the syslog or NetFlow event numbers that correspond to the event types:

Filter Name

Description

Corresponding Syslog Event or Netflow Event

AAA

These are events that the system generates when failed or invalid attempts happen to authenticate, authorize, or use up resources in the network, when AAA is configured.

109001-109035

113001-113027

BotNet

These events get logged when a user attempts to access a malicious network, which might contain a malware-infected host, possibly a BotNet, or when the system detects traffic to or from a domain or an IP address in the dynamic filter block list.

338001-338310

Failover

These events get logged when the system detects errors in stateful and stateless failover configurations or errors in the secondary firewall unit when a failover occurs.

101001-101005, 102001, 103001-103007, 104001-104004, 105001-105048

210001-210022

311001-311004

709001-709007

Firewall Denied

These events get generated when the firewall system denies traffic of a network packet for various reasons, ranging from a packet drop because of the security policy to a drop because the system received a packet with the same source IP and destination IP, which could potentially mean an attack on the network.

Firewall Denied events may be contained in a NetFlow and may be reported with NetFlow event IDs as well as syslog IDs.

106001, 106007, 106012, 106013, 106015, 106016, 106017, 106020, 106021, 106022, 106023, 106025, 106027

Firewall Traffic

These are events that get logged depending on the various connection attempts in the network, user identities, time stamps, terminated sessions, and so on.

Firewall Traffic events may be contained in a NetFlow and may be reported with NetFlow event IDs as well as syslog IDs.

106001-106100, 108001-108007, 110002-110003

201002-201013, 209003-209005, 215001

302002-302304, 302022-302027, 303002-303005, 313001-313008, 317001-317006, 324000-324301, 337001-337009

400001-400050, 401001-401005, 406001-406003, 407001-407003, 408001-408003, 415001-415020, 416001, 418001-418002, 419001-419003, 424001-424002, 431001-431002, 450001

500001-500005, 508001-508002

607001-607003, 608001-608005, 609001-609002, 616001

703001-703003, 726001

IPsec VPN

These events are logged in an IPsec VPN-configured firewall when mismatches occur in IPsec security associations or when the system detects an error in the IPsec packets it receives.

402001-402148, 602102-602305, 702304-702307

NAT

These events are logged in a NAT-configured firewall when NAT entries are created or deleted and when all the addresses in a NAT pool are used up and exhausted.

201002-201013, 202001-202011, 305005-305012

SSL VPN

These events are logged in an SSL VPN-configurated firewall when WebVPN sessions get created or terminated, user access errors, and user activities.

716001-716060, 722001-722053, 723001-723014, 724001-724004, 725001-725015

NetFlow

These events are logged around the IP network traffic as network packets enter and exit the interfaces, timestamps, user identities, and the amount of data transferred.

0, 1, 2, 3, 5

Connection

You can generate events for connections as users generate traffic that passes through the system. Enable connection logging on access rules to generate these events. You can also enable logging on Security Intelligence policies and SSL decryption rules to generate connection events.

Connection events contain data about the detected sessions. The information available for any individual connection event depends on several factors, but in general includes:

  • Basic connection properties: timestamp, source and destination IP address, ingress and egress zones, the device that handled the connection, and so on.

  • Additional connection properties discovered or inferred by the system: applications, requested URLs, or users associated with the connection, and so on.

  • Metadata about why the connection was logged: which configuration handled the traffic, whether the connection was allowed or blocked, details about encrypted and decrypted connections, and so on.

430002, 430003

Intrusion

The system examines the packets that traverse your network for malicious activity that could affect the availability, integrity, and confidentiality of a host and its data. When the system identifies a possible intrusion, it generates an intrusion event, which is a record of the date, time, type of exploit, and contextual information about the source of the attack and its target. Intrusion events are generated for any intrusion rule set to block or alert, regardless of the logging configuration of the invoking access control rule.

430001

File

File events represent files that the system detected, and optionally blocked, in network traffic based on your file policies. You must enable file logging on the access rule that applies the file policy to generate these events.

When the system generates a file event, the system also logs the end of the associated connection regardless of the logging configuration of the invoking access control rule.

430004

Malware

The system can detect malware in network traffic as part of your overall access control configuration. AMP for Firepower can generate a malware event, containing the disposition of the resulting event, and contextual data about how, where, and when the malware was detected. You must enable file logging on the access rule that applies the file policy to generate these events.

The disposition of a file can change, for example, from clean to malware or from malware to clean. If AMP for Firepower queries the AMP cloud about a file, and the cloud determines the disposition has changed within a week of the query, the system generates retrospective malware events.

430005

Security Intelligence

Security Intelligence events are a type of connection event generated by the Security Intelligence policy for each connection that is blocked or monitored by the policy. All Security Intelligence events have a populated Security Intelligence Category field.

For each of these events, there is a corresponding "regular" connection event. Because the Security Intelligence policy is evaluated before many other security policies, including access control, when a connection is blocked by Security Intelligence, the resulting event does not contain the information that the system would have gathered from subsequent evaluation, for example, user identity.

430002, 430003

AI Defense

AI Defense events provide a detailed record of activities within your AI environment, capturing interactions such as prompts submitted, responses generated, and any triggered AI Defense policy violations. These events include key information like timestamps, the application and AI model involved, the specific rule triggered, and the action taken. These event logs enable you to monitor AI usage in real time, detect threats, and enforce security policies effectively.

Deprovisioning Cisco Security Analytics and Logging (SaaS)

If you allow your Cisco Security Analytics and Logging (SaaS) paid subscription to lapse, collection of new events stops immediately. After 90 days from expiry, you will no longer be able to view or query your existing event data. You have 180 days to renew your subscription.

If you allow the 180-day grace period to lapse, the system purges all of your event data. You can no longer view security events on the Event Logging page, nor have dynamic entity modeling (DEM) behavioral analytics applied to your security events and network flow data.

Security Analytics and Logging Licenses

This chapter provides information on Security Analytics and Logging licenses.

Security Analytics and Logging licenses

Security Analytics and Logging subscription overview

You can combine SAL with your Security Cloud Control subscription. When managing your firewalls with Security Cloud Control, you can obtain Security Analytics and Logging entitlement in these ways:

  • Device management with unlimited logging: This option provides a per-device license. It includes device management capabilities for your firewall device and unlimited log storage for a rolling period of 90 days.

  • Device management only with optional cloud logging: This option involves purchasing a per-device license for management only. You can then add Security Analytics and Logging as a separate cloud logging subscription. This allows you to customize logging data storage and log retention based on your specific operational and compliance needs.

90-day free trial

To accurately estimate your daily ingest rate, log in to Security Cloud Control and navigate to the Events & Logs > Events > Event Logging tab to request a 90-day trial. You can purchase the desired subscription plan to continue the service by reviewing the instructions in the Security Cloud Control Firewall Management Ordering Guide.

Security Analytics and Logging paid subscription tiers

If you choose not to use device management with unlimited logging option, you can purchase logging capacity separately. This standalone Security Analytics and Logging subscription provides greater flexibility, longer default retention, and increased storage entitlements. The default minimum retention period for these subscription tiers is 1 year.

Select these flexible Security Analytics and Logging subscription tiers if:

  • You have already purchased your firewall devices as part of a different order.

  • You have specific logging estimates and want to buy a tier based on a fixed amount of ingest, storage, and logging retention.

  • You want a log retention period that is more than 90 days.

Security Analytics and Logging subscription is categorized into three tiers—Essentials, Advantage, and Premier. This table lists the storage capacities and log retention periods for each tier.

Description Retention Period Storage Limit Subscription Term

Cisco SAL Essentials Subscriptions

1, 2, or 3 years

2 TB

0 to 5 years

Cisco SAL Advantage Subscriptions

1, 2, or 3 years

4 TB

0 to 5 years
Cisco SAL Premier Subscriptions

1, 2, or 3 years

10 TB

0 to 5 years

For more information about the subscription plans, refer to the Security Cloud Control Firewall Management Ordering Guide.


Note

For paid subscriptions, Security Analytics and Logging automatically manages your event data to ensure that it aligns with your licensed retention period. Security Analytics and Logging removes event data that is older than your specified retention period on a daily basis, and ensures that you always retain access to all event data within your full retention period.

Estimate your daily ingest rate

Purchase a subscription plan that matches the number of events the Cisco cloud receives from your onboarded firewall devices on a daily basis. This is called your daily ingest rate. You can use the Logging Volume Estimator tool to estimate your daily ingest rate and as that rate changes you can update your subscription plan.

Subscribe to a Security Analytics and Logging license

Start a Security Analytics and Logging trial subscription

Purchase a data storage plan that matches the daily event volume your onboarded security devices send to Cisco cloud. This volume is referred to as your daily ingest rate. Before making a purchase, participate in a free trial of Security Analytics and Logging to accurately estimate your daily ingest rate.

  • With this trial plan, you gain access to all Security Analytics and Logging features for 90 days.

  • During the 90-day trial period, your onboarded firewalls send events to Security Analytics and Logging. Monitor your event ingestion rates, understand your storage requirements, and evaluate performance. This data helps you to plan and select the most appropriate paid subscription.

  • If you activate a paid Security Analytics and Logging subscription while a trial is active, Security Cloud Control replaces the trial license for the product instance with the paid license and ends the trial.

  • If you choose not to apply the paid subscription to the trial, event ingestion automatically stops after 90 days. After this, you cannot access Security Analytics and Logging features. However, your existing log data remains in the Security Analytics and Logging cloud for an additional 90 days from the trial expiry date.


    Note

    If you do not subscribe to a paid Security Analytics and Logging license within this 90-day grace period, all your trial data is permanently deleted.

Order a paid Security Analytics and Logging subscription

To continue using Security Analytics and Logging after your trial, or to upgrade your existing logging capabilities:

  1. Use the insights that you gained from your trial (daily ingest rate, required retention, storage volume) to determine the most suitable Security Analytics and Logging subscription plan.

  2. Work with your Cisco representative or authorized partner to purchase the appropriate Security Analytics and Logging subscription.

Claim your Security Analytics and Logging subscription

After you purchase a new Security Analytics and Logging subscription, you receive a claim code to activate it within Security Cloud Control. A welcome email containing your subscription claim code is automatically sent to the Provisioning Contact you specified during the purchasing process. If you included an End Customer contact, they also receive a copy. You will receive this email on the requested start date of your subscription.

A Security Cloud Control administrator uses the claim code to activate the subscription for their organization. For detailed instructions on claiming and activating subscriptions, refer to Claim a Subscription.

Renew your Security Analytics and Logging subscription

Maintaining an active Security Analytics and Logging subscription ensures continuous logging and access to your historical data.

  • If your Security Analytics and Logging subscription expires without renewal, event ingestion from your firewalls stops immediately.

  • You can continue to view and search existing event data for 90 days after the subscription expires. After 90 days, event data is no longer accessible.

  • Your existing data remains in the Security Analytics and Logging cloud for a 180-day grace period from the subscription expiry date.

  • If the Security Analytics and Logging subscription is not renewed within this 180-day grace period, all your event data is permanently deleted from the Security Analytics and Logging cloud.

Frequently asked questions about Security Analytics and Logging license

Which data gets counted against my Security Analytics and Logging allotment?

All events sent to the Cisco cloud directly or to the Secure Event Connector accumulate in Security Analytics and Logging and count against your data allotment.

Filtering the events viewer does not decrease the number of stored events in Security Analytics and Logging. It only reduces the number of events you see in the events viewer.

We're using up our storage allotment quickly. What should I do?

Here are two approaches to address that problem:

  • Request more storage.

  • Consider reducing the number of rules that log events. You can log events from SSL policy rules, security intelligence rules, access control rules, intrusion policies, and file and malware policies. Review your current logging settings to determine if you need to log events from all the rules and policies that you have configured.

What happens to my data if my Security Analytics and Logging license expires?

If your paid Security Analytics and Logging license expires, event ingestion from your firewalls stops immediately. However, your existing data remains accessible in the Security Analytics and Logging cloud for a 180-day grace period. If you renew your paid license during this grace period, your service continues without interruption. If you do not renew within these 180 days, all your data is permanently deleted.

If I purchase a Security Analytics and Logging subscription with a 1-year retention period and a 5-year term, will my data be stored for all 5 years?

The retention period defines how long each log is stored. With a 1-year retention period, only the most recent 1-year log data is available at any given time. Log data older than 1 year is overwritten or deleted when new data is collected. A 5-year term means that data for that duration will continue to be ingested, but the retention limit is applicable to the log data itself.

Secure Event Connectors

This chapter provides information about secure event connectors.

About Secure Event Connectors

The Secure Event Connector (SEC) is a component of the Security Analytics and Logging SaaS solution. It receives events from ASA , and FDM-managed devices and forwards them to the Cisco cloud. Security Cloud Control displays the events on the Event Logging page enabling you to analyze the security events from all devices in one place.

The SEC is installed on a Secure Device Connector deployed in your network, on its own Security Cloud Control Connector virtual machine deployed in your network, or on an AWS Virtual Private Cloud (VPC).

Secure Event Connector ID

You may need the ID of the SEC when working with Cisco Technical Assistance Center (TAC) or other Security Cloud Control Support. That ID is found on the Secure Connectors page in Security Cloud Control. To find the SEC ID:

  1. From the Security Cloud Control menu on the left, choose Administration > Secure Connectors.

  2. Click the SEC you wish to identify.

  3. The SEC ID is the ID listed above the Tenant ID in the Details pane.

Installing Secure Event Connectors

Secure Event Connectors (SECs) can be installed on a tenant with or without an SDC.

You can install one SEC on the same virtual machine as a Secure Device Connector, if you have one; or you can install the SEC on it's own Security Cloud Control Connector virtual machine that you maintain in your network.

Install a Secure Event Connector on an SDC Virtual Machine

The Secure Event Connector (SEC) receives events from ASA and FDM-managed devices and forwards them to the Cisco cloud. Security Cloud Control displays the events on the Event Logging page enabling you to analyze the security events from all devices in one place.

You can install one SEC on the same virtual machine as a Secure Device Connector, if you have one; or you can install the SEC on it's own Security Cloud Control Connector virtual machine that you maintain in your network.

This article describes installing an SEC on the same virtual machine as an SDC. If you want to install more SECs see Installing an SEC Using a Security Cloud Control Image or Install an SEC Using Your VM Image.

Before you begin

  • Purchase the Cisco Security and Analytics Logging license. If you want to try Cisco Security and Analytics Logging out first, log in to Security Cloud Control, and on the main navigation bar, choose Events & Logs > Events > Event Logging and click Request Trial.

  • Make sure your SDC has been installed. For more information, see Deploy a VM for Running the Secure Device Connector and Secure Event Connector.

  • Make sure the SDC is communicating with Security Cloud Control:

    1. In the left pane, click Administration > Secure Connectors.

    2. Make sure that the SDC's last heartbeat was less than 10 minutes prior to the installation of the SEC and that the SDC's status is active.

  • System Requirements - Assign additional CPUs and memory to the virtual machine running the SDC:

    • CPU: Assign an additional 4 CPUs to accommodate the SEC to make a total of 6 CPU.

    • Memory: Assign an additional 8 GB of memory for the SEC to make a total of 10 GB of memory.

      After you have updated the CPU and memory on the VM to accommodate the SEC, power on the VM and ensure that the Secure Connectors page indicates that the SDC is in the "Active" state.

Procedure

Step 1

Log in to Security Cloud Control.

Step 2

From the Security Cloud Control home page, choose Products > Firewall.

Step 3

In the left pane, click Administration > Secure Connectors.

Step 4

Click the icon and then click Secure Event Connector.

Step 5

Skip Step 1 of the wizard and go to Step 2. In step 2 of the wizard, click the link to Copy SEC Bootstrap Data.

Step 6

Open a terminal window and log into the SDC as the "cdo" user.

Step 7

Once logged in, switch to the "sdc" user. When prompted for a password, enter the password for the "cdo" user. Here is an example of those commands: 

[cdo@sdc-vm ~]$ sudo su sdc
[sudo] password for cdo: <type password for cdo user>
[sdc@sdc-vm ~]$

Step 8

At the prompt, run the sec.sh setup script: 

[sdc@sdc-vm ~]$ /usr/local/cdo/toolkit/sec.sh setup

Step 9

At the end of the prompt, paste the bootstrap data you copied in step 4 and press Enter. 

Please copy the bootstrap data from Setup Secure Event Connector page of Security Cloud Control: KJHYFuYTFuIGhiJKlKnJHvHfgxTewrtwE
RtyFUiyIOHKNkJbKhvhgyRStwterTyufGUihoJpojP9UOoiUY8VHHGFXREWRtygfhVjhkOuihIuyftyXtfcghvjbkhB=

After the SEC is onboarded, the sec.sh runs a script to check on the health of the SEC. If all the health checks are "green," the health check sends a sample event to the Event Log. The sample event shows up in the Event Log as a policy named "sec-health-check."

If you receive a message that the registration failed or that the SEC onboarding failed, go to Troubleshooting Secure Event connector Onboarding Failures.

Step 10

Determine if the VM on which the SDC and SEC are running needs additional configuration:

Installing an SEC Using a Security Cloud Control Image

The Secure Event Connector (SEC) forwards events from ASA and FTD to the Cisco cloud so that you can view them in the Event Logging page in Security Cloud Control.

You can install more than one Secure Event Connector (SEC) on your tenant and direct events from your ASAs and FDM-managed devices to any of the SECs you install. Having multiple SECs allows you to have SECs installed in different locations and distribute the work of sending events to the Cisco cloud.

Installing an SEC is a two part process:

  1. Install a Security Cloud Control Connector, to Support a Secure Event Connector, Using a Security Cloud Control VM Image You need one Security Cloud Control Connector for every SEC you install. The Security Cloud Control Connector is different than a Secure Device Connector (SDC).

  2. Install the Secure Event Connector on your Security Cloud Control Connector Virtual Machine.

Install an SEC Using Your VM Image

The Secure Event Connector (SEC) forwards events from ASA and FTD to the Cisco cloud so that you can view them in the Event Logging page and investigate them with Secure Cloud Analytics, depending on your licensing.

You can install more than one Secure Event Connector (SEC) on your tenant and direct events from your ASAs and FDM-managed devices to any of the SECs you install. Having multiple SECs allows you to have SECs installed in different regions and distribute the work of sending events to the Cisco cloud.

Installing multiple SECs using your own VM image is a three part process. You must perform each of these steps:

  1. Install a Security Cloud Control Connector to Support an SEC Using Your VM Image

  2. Additional Configuration for SDCs and Security Cloud Control Connectors Installed on a VM You Created

  3. Install the Secure Event Connector


Note

Using a Security Cloud Control VM image for the Security Cloud Control Connector is the easiest, most accurate, and preferred method of installing a Security Cloud Control connector. If you want to use that method, see Installing an SEC Using a Security Cloud Control Image.

What to do next:

Continue to Install a Security Cloud Control Connector to Support an SEC Using Your VM Image

Install a Security Cloud Control Connector to Support an SEC Using Your VM Image

The Security Cloud Control Connector VM is a virtual machine on which you install an SEC. The purpose of the Security Cloud Control Connector is solely to support an SEC for Cisco Security Analytics and Logging (SaaS) customers.

This is the first of three steps you need to complete in order install and configure your Secure Event Connector (SEC). After this procedure, you need to complete the following procedures:

Before you begin

  • Purchase the Cisco Security and Analytics Logging, Logging and Troubleshootinglicense, you may also purchase the Logging Analytics and Detection and Total Network Analytics and Monitoring licenses to apply Secure Cloud Analytics to the events.

    If you would rather, you can request a trial version of Security Analytics and Logging by logging in to Security Cloud Control, and on the main navigation bar, choose Events & Logs > Events > Event Logging and click Request Trial.

  • Security Cloud Control requires strict certificate checking and does not support a Web/Content Proxy between the Security Cloud Control Connector and the Internet.

  • The Security Cloud Control Connector must have full outbound access to the Internet on TCP port 443.

  • Review Connect to Security Cloud Control using Secure Device Connectorto ensure proper network access for the Security Cloud Control Connector.

  • VMware ESXi host installed with vCenter web client or ESXi web client.


    Note
    We do not support installation using the vSphere desktop client.

  • ESXi 5.1 hypervisor.

  • Ubuntu 22.04 and Ubuntu 24.04.

  • System requirements for a VM to host only a Security Cloud Control Connector and an SEC:

    • CPU: Assign 4 CPUs to accommodate the SEC.

    • Memory: Assign 8 GB of memory for the SEC.

    • Disk Space: 64 GB

  • Users performing this procedure should be comfortable working in a Linux environment and using the vi visual editor for editing files.

  • Gather this information before you begin the installation:

    • Static IP address you want to use for your Security Cloud Control Connector.

    • Passwords for the root and Security Cloud Control users that you create during the installation process.

    • The IP address of the DNS server your organization uses.

    • The gateway IP address of the network the Security Cloud Control Connector address is on.

    • The FQDN or IP address of your time server.

  • The Security Cloud Control Connector virtual machine is configured to install security patches on a regular basis and in order to do this, opening port 80 outbound is required.

  • Before you get started: Do not copy and paste the commands in this procedure into your terminal window, type them instead. Some commands include an "n-dash" and in the cut and paste process, these commands can be applied as an "m-dash" and that may cause the command to fail.

Procedure

Step 1

Log on to Security Cloud Control.

Step 2

From the Security Cloud Control home page, choose Products > Firewall.

Step 3

From the left pane, Administration > Secure Connectors.

Step 4

Click the icon and then click Secure Event Connector.

Step 5

Using the link provided, copy the SEC Bootstrap Data in step 2 of the "Deploy an On-Premises Secure Event Connector" window.

Step 6

Once installed, configure basic networking such as specifying the IP address for the Security Cloud Control Connector, the subnet mask, and gateway.

Step 7

Configure a DNS (Domain Name Server) server.

Step 8

Configure a NTP (Network Time Protocol) server.

Step 9

Install an SSH server for easy interaction with Security Cloud Control Connector's CLI.

Step 10

Install the AWS CLI package (https://docs.aws.amazon.com/cli/latest/userguide/awscli-install-linux.html)

Note

 

Do not use the --user flag.

Step 11

Install the Docker CE packages (https://docs.docker.com/install/linux/docker-ce/centos/#install-docker-ce)

Note

 

Use the "Install using the repository" method.

Step 12

Start the Docker service and enable it to start on boot:

[root@sdc-vm ~]# systemctl start docker
 [root@sdc-vm ~]# systemctl enable docker 
Created symlink from /etc/systemd/system/multiuser.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

Step 13

Create two users: Security Cloud Control and sdc. The Security Cloud Control user will be the one you log-into to run administrative functions (so you don't need to use the root user directly), and the sdc user will be the user to run the Security Cloud Control Connector docker container. 

[root@sdc-vm ~]# useraddSecurity Cloud Control
 [root@sdc-vm ~]# useradd sdc –d /usr/local/Security Cloud Control

Step 14

Configure the sdc user to use crontab:

[root@sdc-vm ~]# touch /etc/cron.allow
[root@sdc-vm ~]# echo "sdc" >> /etc/cron.allow

Step 15

Set a password for the Security Cloud Control user. 

[root@sdc-vm ~]# passwd Security Cloud Control 
Changing password for user Security Cloud Control. 
New password: <type password>  
Retype new password: <type password> 
passwd: all authentication tokens updated successfully.

Step 16

Add the Security Cloud Control user to the "wheel" group to give it administrative (sudo) privileges. 

[root@sdc-vm ~]# usermod -aG wheelSecurity Cloud Control
 [root@sdc-vm ~]#

Step 17

When Docker is installed, there is a user group created. Depending on the version of CentOS/Docker, this may be called either "docker" or "dockerroot". Check the /etc/group file to see which group was created, and then add the sdc user to this group. 


 [root@sdc-vm ~]# grep docker /etc/group 
docker:x:993:
[root@sdc-vm ~]# 
[root@sdc-vm ~]# usermod -aG docker sdc 
[root@sdc-vm ~]#

Step 18

If the /etc/docker/daemon.json file does not exist, create it, and populate with the contents below. Once created, restart the docker daemon.

Note

 

Make sure that the group name entered in the "group" key matches the group you found in the /etc/group file. 

 [root@sdc-vm ~]# cat /etc/docker/daemon.json 
{
 "live-restore": true, 
 "group": "docker" 
} 
[root@sdc-vm ~]# systemctl restart docker 
[root@sdc-vm ~]#

Step 19

If you are currently using a vSphere console session, switch over to SSH and log in as the Security Cloud Control user. Once logged in, change to the sdc user. When prompted for a password, enter the password for the Security Cloud Control user. 

[Security Cloud Control@sdc-vm ~]$ sudo su sdc 
[sudo] password for Security Cloud Control: <type password for Security Cloud Control user > 
[sdc@sdc-vm ~]$

Step 20

Change directories to /usr/local/Security Cloud Control.

Step 21

Create a new file called bootstrapdata and paste the bootstrap data from Step 1 of the deployment wizrd into this file. Save the file. You can use vi or nano to create the file.

Step 22

The bootstrap data comes encoded in base64. Decode it and export it to a file called extractedbootstrapdata

 [sdc@sdc-vm ~]$ base64 -d /usr/local/Security Cloud Control/bootstrapdata > /usr/local/Security Cloud Control/extractedbootstrapdata 
[sdc@sdc-vm ~]$

Run the cat command to view the decoded data. The command and decoded data should look similar to this: 

[sdc@sdc-vm ~]$ cat /usr/local/Security Cloud Control/extractedbootstrapdata 
Security Cloud Control_TOKEN="<token string>" 
Security Cloud Control_DOMAIN="www.defenseorchestrator.com" 
Security Cloud Control_TENANT="<tenant-name>" 
<Security Cloud Control_URL>/sdc/bootstrap/Security Cloud Control_acm="https://www.defenseorchestrator.com/sdc/bootstrap/tenant-name/<tenant-name-SDC>" 
ONLY_EVENTING="true"

Step 23

Run the following command to export the sections of the decoded bootstrap data to environment variables. 


[sdc@sdc-vm ~]$ sed -e 's/^/export /g' extractedbootstrapdata > secenv && source secenv 
[sdc@sdc-vm ~]$

Step 24

Download the bootstrap bundle from Security Cloud Control. 

 [sdc@sdc-vm ~]$ curl -H "Authorization: Bearer $Security Cloud Control_TOKEN" "$Security Cloud Control_BOOTSTRAP_URL" -o $Security Cloud Control_TENANT.tar.gz 
100 10314 100 10314 0 0 10656 0 --:--:-- --:--:-- --:--:-- 10654

    [sdc@tenant toolkit]$ sdc eventing delete CDO_{tenant-name}

Step 4

Confirm your intention to remove the SEC files.

Finding Your Device's TCP, UDP, and NSEL Port Used for Secure Logging Analytics (SaaS)

Secure Logging Analytics (SaaS) allows you to send events from your ASA or FDM-managed devices to certain UDP, TCP, or NSEL ports on the Secure Event Connector (SEC). The SEC then forwards those events to the Cisco cloud.

If these ports aren't already in use, the SEC makes them available to receive events and the Secure Logging Analytics (SaaS) documentation recommends using them when you configure the feature.

  • TCP: 10125

  • UDP: 10025

  • NSEL: 10425

If those ports are already in use, before you configure Secure Logging Analytics (SaaS), look at your SEC device details to determine what ports it is actually using to receive events.

To find the port numbers the SEC uses:

Procedure

Step 1

From the Security Cloud Control home page, choose Products > Firewall.

Step 2

From the left pane, click Administration > Integrations > Firewall Management Center and then click the Secure Connectors tab.

Step 3

In the Secure Connectors page, select the SEC you want to send events to.

Step 4

In the Details pane, you will see the TCP, UDP, and NetFlow (NSEL) port you should send events to.

Secure Logging Analytics (SaaS) for FDM-Managed Devices

About Secure Analytics and Logging (SaaS) for FDM-Managed Devices

Cisco Security Analytics and Logging (SaaS) allows you to capture connection, intrusion, file, malware, and Security Intelligence events from all of your FDM-managed devices and view them in one place in Security Cloud Control.

The events are stored in the Cisco cloud and viewable from the Event Logging page in Security Cloud Control where you can filter and review them to gain a clear understanding of what security rules are triggering in your network. The Logging and Troubleshooting package gives you these capabilities.

With the Logging Analytics and Detection package (formerly Firewall Analytics and Logging package), the system can apply Secure Cloud Analytics dynamic entity modeling to your FDM-managed device events, and use behavioral modeling analytics to generate Secure Cloud Analytics observations and alerts. If you obtain a Total Network Analytics and Monitoring package, the system applies dynamic entity modeling to both your FDM-managed device events and your network traffic, and generates observations and alerts. You can cross-launch from Security Cloud Control to a Cisco Secure Cloud Analytics portal provisioned for you, using Cisco Single Sign-On.

How FDM Events are Displayed in the Security Cloud Control Events Viewer

Connection, intrusion, file, malware, and Security Intelligence events are generated when an individual rule is configured to log events and network traffic matches the rule criteria. After the events are stored in the Cisco cloud, you can view them in Security Cloud Control. There are two methods of configuring your FDM-managed device to send events to the Cisco cloud:

  • You can install multiple Secure Event Connectors (SECs) and send events generated by a rule, on any device, to any of the SECs as if it were a syslog server. The SEC then forwards the event to the Cisco cloud.

  • If your FDM-managed device was onboarded to Security Cloud Control using a registration key, you can send events directly to the Cisco cloud using a control in the Secure Firewall Device Manager.

How an Event is Sent to the Cisco Cloud Using the Secure Event Connector

With the basic Logging and Troubleshooting license, this is how a Secure Firewall Device Manager event reaches the Cisco cloud:

  1. You onboard your FDM-managed device to Security Cloud Control using username and password or by using a registration key.

  2. You configure individual rules, such as access control rules, Security Intelligence rules, and SSL decryption rules, to forward events to any one of your SECs as if it were a syslog server. In access control rules, you can also enable file and malware policies, and intrusion policies, and forward events generated by those polices to the SEC.

  3. You configure File/Malware logging in System Settings > Logging for file events.

  4. You configure Intrusion Logging in System Settings > Logging for intrusion events.

  5. The SEC forwards the events to the Cisco cloud where the events are stored.

  6. Security Cloud Control displays events from the Cisco cloud in its Events Logging page based on the filters you set.

With the Logging Analytics and Detection or Total Network Analytics and Monitoring license, the following also occur:

  1. Cisco Secure Cloud Analytics applies analytics to the Secure Firewall Device Manager connection events stored in the Cisco cloud.

  2. Generated observations and alerts are accessible from the Secure Cloud Analytics portal associated with your Security Cloud Control portal.

  3. From the Security Cloud Control portal, you can cross-launch your Secure Cloud Analytics portal to review these observations and alerts.

How Events are Sent Directly from an Secure Firewall Device Manager to the Cisco Cloud

With the basic Logging and Troubleshooting license, this is how Secure Firewall Device Manager events reach the Cisco cloud:

  1. You onboard your FDM-managed device to Security Cloud Control using a registration token.

  2. You configure individual rules, such as access control rules, Security Intelligence rules, and SSL decryption rules, to log events but you don't specify a syslog server for them to be sent to. In access control rules, you can also enable file and malware policies and intrusion policies, and forward events generated by those polices to the Cisco cloud.

  3. File events and Intrusion events are sent to the Cisco cloud if file and malware policies and intrusion policies are configured in the access control rules to log connection events.

  4. You activate Cloud Logging on the Secure Firewall Device Manager and the events logged in the various rules are sent to the Cisco cloud.

  5. Security Cloud Control pulls events from the Cisco cloud based on the filters you set and displays them in its Events viewer.

With the Logging Analytics and Detection or Total Network Analytics and Monitoring license, the following also occur:

  1. Cisco Secure Cloud Analytics applies analytics to the Secure Firewall Device Manager connection events stored in the Cisco cloud.

  2. Generated observations and alerts are accessible from the Secure Cloud Analytics portal associated with your Security Cloud Control portal.

  3. From the Security Cloud Control portal, you can cross-launch your Secure Cloud Analytics portal to review these observations and alerts.

Components in the Solution

Cisco Security Analytics and Logging (SaaS) uses these components to deliver events to Security Cloud Control:

Secure Device Connector (SDC)-The SDC connects Security Cloud Control to your FDM-managed devices. The login credentials for the FDM-managed devices are stored on the SDC.

See Secure Device Connector for more information.

Secure Event Connector (SEC)-The SEC is an application that receives events from your FDM-managed devices and forwards them to the Cisco cloud. Once in the Cisco cloud, you can view the events on Security Cloud Control's Event Logging page or analyze them with Cisco Secure Cloud Analytics. You may have one or more SECs associated with your tenant. Depending on your environment, you install the Secure Event Connector on a Secure Device Connector or a Security Cloud Control Connector VM.

Secure Firewall Device Manager-The FDM-managed device is Cisco's next generation firewall. Beyond stateful inspection of network traffic and access control, the FDM-managed device provides capabilities such as protection from malware and application-layer attacks, integrated intrusion prevention, and cloud-delivered threat intelligence.

If you have a Logging Analytics and Detection or Total Network Analytics and Monitoring license, Cisco Security Analytics and Logging (SaaS) uses Cisco Secure Cloud Analytics to further analyze events delivered to Security Cloud Control.

Cisco Secure Cloud Analytics-Secure Cloud Analytics applies dynamic entity modeling to events, generating detections based on this information. This provides a deeper analysis of telemetry gathered from your network, allowing you to identify trends and examine anomalous behavior in your network traffic.

Licensing

To configure this solution you need the following accounts and licenses:

Security Cloud Control. You must have a Security Cloud Control tenant.

Secure Device Connector. There is no separate license for a SDC.

Secure Event Connector. There is no separate license for a SEC.

Secure Logging Analytics (SaaS). You need to buy the Logging and Troubleshooting license. The goal of this package is to provide network operations teams with real-time and historical events derived from their on-boarded FDM-managed devices for the purposes of troubleshooting and analyzing traffic in their network.

You can also buy a Logging Analytics and Detection or Total Network Analytics and Monitoring license to apply Cisco Secure Cloud Analytics. The goal of these packages is to provide network operations teams additional insight into the events (and network traffic with the Total Network Analytics and Monitoring license) to better identify possible anomalous behavior and respond to it.

FDM-Managed Device. You need to have the following licenses to run the FDM-managed device and create rules that generate security events:

License

Duration

Granted Capabilities

Essentials(automatically included)

Perpetual

All features not covered by the optional term licenses.

You must also specify whether to Allow export-controlled functionality on the products registered with this token. You can select this option only if your country meets export-control standards. This option controls your use of advanced encryption and the features that require advanced encryption.

Term-based

Intrusion detection and prevention-Intrusion policies analyze network traffic for intrusions and exploits and, optionally, drop offending packets.

File control-File policies detect and, optionally, block users from uploading (sending) or downloading (receiving) files of specific types. AMP for Firepower, which requires a Malware license, allows you to inspect and block files that contain malware. You must have the Threat license to use any type of File policy.

Security Intelligence filtering-Drop selected traffic before the traffic is subjected to analysis by access control rules. Dynamic feeds allow you to immediately drop connections based on the latest intelligence.

Malware

Term-based

File policies that check for malware, which use Cisco Advanced Malware Protection (AMP) with AMP for Firepower (network-based Advanced Malware Protection) and Cisco Threat Grid.

File policies can detect and block malware in files transmitted over your network.

Data Plans

You need to buy a data storage plan that reflects the number of events the Cisco cloud receives from your on-boarded FDM-managed devices on a daily basis. The best way to determine your ingest rate is to participate in a free trial of Secure Logging Analytics (SaaS) (SaaS) before you buy it. This will give you a good estimate of your event volume. In addition, you can use the Logging Volume Estimator Tool.


Caution

It is possible to configure your FDM-managed device to send events to the Cisco cloud directly and by way of the SEC simultaneously. If you do this, the same event will be "ingested" twice and counted against your data plan twice, though it will only be stored in the Cisco cloud once. Be careful to send events to the Cisco cloud using one method or the other to avoid incurring unnecessary fees.

Data plans are available in 1 GB daily volumes increments, and in 1, 3 or 5 year terms. See the Secure Logging Analytics (SaaS) Ordering Guide for information about data plans.


Note

If you have a Security Analytics and Logging license and data plan, then obtain a different license at a later date, that alone does not require you to obtain a different data plan. If your network traffic throughput changes and you obtain a different data plan, that alone does not require you to obtain a different Security Analytics and Logging license.

30-day Free Trial

You can request a 30-day risk-free trial by logging in to Security Cloud Control and navigating to Events & Logs > Events > Event Logging. On completion of the 30-day trial, you can order the desired event data volume to continue the service from Cisco Commerce Workspace (CCW), by following the instructions in the Secure Logging Analytics (SaaS) ordering guide.

Implementing Secure Logging Analytics (SaaS) for FDM-Managed Devices

Before you Begin

  • Review About Secure Analytics and Logging (SaaS) for FDM-Managed Devices to learn about:

    • How events are sent to the Cisco cloud

    • Applications in the solution

    • Licenses you need

    • Data plan you need

  • You have contacted your managed service provider or Security Cloud Control Sales representative and you have a Security Cloud Control tenant.

  • Your tenant may or may not use an Secure Device Connector (SDC) for Security Cloud Control to connect with your FDM-managed devices. Your tenant should have an SDC installed for those FDM-managed devices that you onboard with device credentials, it is considered a best practice. If you onboard your FDM-managed devices with registration key or serial number you do not need an SDC.

  • If you have installed an SDC for your tenant, ensure your SDC status is Active and has recorded a recent heartbeat.

  • If you are installing an SDC:

  • You can install more than one SEC for your tenant and you can send events from any Firewall Device Manager to any one SEC onboarded to your tenant.

  • If you are sending events directly to the Cisco cloud from the Firewall Device Manager, you have opened up outbound access on port 443 on the management interface.

  • You have established two-factor authentication for users of your account.

About Security Analytics and Logging(SaaS) for Firewall Threat Defense

SAL (SaaS) allows you to capture connection, intrusion, file, malware, and Security Intelligence events from all of your Firewall Threat Defense devices and view them in one place in Security Cloud Control. The events are stored in the Cisco cloud and are viewable from the Event Logging page in Security Cloud Control, where you can filter and review them to gain a clear understanding of what security rules are triggering in your network.

With additional licensing, after you capture these events, you can cross-launch from Security Cloud Control to the Secure Cloud Analytics portal provisioned for you. Secure Cloud Analytics is a software as a service (SaaS) solution that tracks the state of your network by performing a behavioral analysis on events and network flow data. By gathering information about your network traffic from sources including firewall events and network flow data, it creates observations about the traffic and automatically identifies roles for network entities based on their traffic patterns. Using this information combined with other sources of threat intelligence, such as Talos, Secure Cloud Analytics generates alerts, which constitute a warning that there is behavior that may be malicious in nature. Along with the alerts, Secure Cloud Analytics provides network and host visibility, and contextual information it has gathered to provide you with a better basis to research the alert and locate sources of malicious behavior.

How Firewall Threat Defense Events are Displayed in Security Cloud Control Using a Direct Connection

This diagram describes how Firewall Threat Defense devices that are managed by Security Cloud Control shares security events (connection, security-related connection, intrusion, file, and malware events) with Security Cloud Control.

Figure 1. How Firewall Threat Defense events are displayed in Security Cloud Control

Step

Description

1

You configure the Firewall Threat Defense device to send security events directly to Cisco cloud.

Security events are generated when logging is enabled on the Firewall Threat Defense device, and network traffic matches access control rule criteria. The Firewall Threat Defense device sends the events directly to Security Services Exchange.

2

Security Services Exchange aggregates the event data from all the Firewall Threat Defense devices, converts it to JSON format, and sends it to Security Analytics and Logging for storage.

3

Security Analytics and Logging process the event data using various services to classify and enrich it for use by the Security Cloud Control.

4

Security Analytics and Logging stores the event data in the cloud data store. Security Cloud Control queries the stored data to provide SOC analysts with the relevant information.

View Events in Security Cloud Control

This chapter provides information on how to view live and historical events in Security Cloud Control.

Viewing Live Events

The Live events page shows the most recent 500 events that match the filter and search criteria you entered. If the Live events page displays the maximum of 500 events, and more events stream in, Security Cloud Control displays the newest live events, and transfers the oldest live events to the Historical events page, keeping the total number of live events at 500. That transfer takes roughly a minute to perform. If no filtering criteria is added, you will see all the latest Live 500 events generated by rules configured to log events.

The event timestamps are shown in UTC.

Changing the filtering criteria, whether live events are playing or paused, clears the events screen and restarts the collection process.

To see live events in the Security Cloud Control Events viewer:

Procedure

Step 1

From the Security Cloud Control home page, choose Products > Firewall.

Step 2

In the left pane, choose Events & Logs > Events > Event Logging.

Step 3

Click the Live tab.

What to do next

See how to play and pause events by reading .

Play/Pause Live Events

You can "play" or "pause" live events as they stream in. If live events are "playing," Security Cloud Control displays events that match the filtering criteria specified in the Events viewer in the order they are received. If events are paused, Security Cloud Control does not update the Live events page until you restart playing live events. When you restart playing events, Security Cloud Control begins populating events in the Live page from the point at which you restarted playing events. It doesn't back-fill the ones you missed.

To view all the events that Security Cloud Control received whether you played or paused live event streaming, click the Historical tab.

Auto-pause Live Events

After displaying events for about 5 consecutive minutes, Security Cloud Control warns you that it is about to pause the stream of live events. At that time, you can click the link to continue streaming live events for another 5 minutes or allow the stream to stop. You can restart the live events stream when you are ready.

Receiving and Reporting Events

There may be a small lag between the Secure Event Connector or the Security Service Exchange receiving events and Security Cloud Control posting events in the Live events viewer. You can view the gap on the Live page. The time stamp of the event is the time it was received by Secure Event Connector or the Security Service Exchange.

View Historical Events

The Live events page shows the most recent 500 events that match the filter and search criteria you entered. Events older than the most recent 500 are transferred to the Historical events table. That transfer takes roughly a minute to perform. You can then filter all the events you have stored to find events you're looking for.

To view historical events:

Procedure

Step 1

From the Security Cloud Control home page, choose Products > Firewall.

Step 2

In the navigation pane, choose Events & Logs > Events > Event Logging.

Step 3

Click the Historical tab. By default, when you open the Historical events table, the filter is set to display the events collected within the last hour.

The event attributes are largely the same as what is reported by Firepower Device Manager (FDM) or the Adaptive Security Device Manager (ASDM).

Customize the Events View

Any changes made to the Event Logging page are automatically saved for when you navigate away from this page and come back at a later time.


Note

The Live and Historical events view have the same configuration. When you customize the events view, these changes are applied to both the Live and Historical view.

Show or Hide Columns

You can modify the event view for both live and historical events to only include column headers that apply to the view you want. Click the column filter icon located to the right of the columns, select or deselect the columns you want, and then click Apply.

Figure 2. Show or Hide Columns
Screen capture of Customize Table pane

Columns with asterisks are provided within the event table by default, although you can remove them at any time.

Search and Add Columns

You can search for more columns, which are not part of the default list, and add them to the event view for both live and historical events. Note that adding many columns for customizing the table may reduce performance. Consider using fewer columns for faster data retrieval.

Alternatively, click the + icon next to an event to expand it and view the hidden columns. Note that some of the event fields displayed when you expand an event can have a different name compared to the corresponding column name. To correlate the events fields displayed when you expand an event to the corresponding column name, see Correlate Threat Defense Event Fields and Column Names.

Reorder the Columns

You can reorder the columns of the event table. Click the column filter icon located to the right of the columns to view the list of selected columns. Then, drag and drop the columns into the order you want. The column at the top of the list in the drop-down menu appears as the left-most column in the event table.

Correlate Firewall Threat Defense Event Fields and Column Names

On the Security Cloud Control Event Logging page, you can click on any event to expand its details and view all the associated event fields. Note that the names of some event fields may differ from those of the column headers in the Security Cloud Control event viewer where the values of these fields are displayed. The table below lists those Firewall Threat Defense event fields that have differing column names and provides a comparison between the Firewall Threat Defense event field and the respective column name.

This table describes the default column headers:

Column Header

Description

Date/Time

The time the device generated the event. By default, event timestamps are displayed in your Local time zone. To view event timestamps in UTC, see Change the Time Zone for the Event Timestamps

Device Type

FTD (Firepower Threat Defense)

Event Type

This composite column can have any of the following:

  • FTD Event Types

    • Connection: Displays connection events from access control rules.

    • File: Displays events reported by file policies in access control rules.

    • Intrusion: Displays events reported by intrusion policy in access control rules.

    • Malware: Displays events reported by malware policies in access control rules.

  • ASA Event Types: These event types represent groups of syslog or NetFlow events. See ASA Event Types for more information about which syslog ID or which NetFlow ID is included in which group.

    • Parsed Events: Parsed syslog events contain more event attributes than other syslog events and Security Cloud Control is able to return search results based on those attributes more quickly. Parsed events are not a filtering category; however, parsed event IDs are displayed in the Event Types column in italics. Event IDs that are not displayed in italics are not parsed.

    • ASA NetFlow Event IDs: All Netflow (NSEL) events from ASA appear here.

Sensor ID / Hostname

The Sensor ID is the IP address from which events are sent to Security Service Exchange or Secure Event Connector.

This is typically the management interface on the threat defense or the ASA.

Initiator IP

This is the IP address of the source of the network traffic. The value of the Initiator address field corresponds to the value of the InitiatorIP field in the event details. You can enter a single address, such as 10.10.10.100, or a network defined in CIDR notation such as 10.10.10.0/24.

Responder IP

This is the destination IP address of the packet. The value of the Destination address field corresponds to the value in the ResponderIP field in the event details. You can enter a single address, such as 10.10.10.100, or a network defined in CIDR notation such as 10.10.10.0/24.

Port

The port or ICMP code used by the session responder. The value of the destination port corresponds to the value of the ResponderPort in the event details.

Protocol

It represents the protocol in the events.

Action

Specifies the security action defined by the rule. The value you enter must be an exact match to what you want to find; however, the case doesn't matter. Enter different values for connection, file, intrusion, malware, syslog, and NetFlow event types:

  • For connection event types, the filter searches for matches in the AC_RuleAction attribute. Those values could be Allow, Block, Trust.

  • For file event types, the filter searches for matches in the FileAction attribute. Those values could be Allow, Block, Trust.

  • For intrusion event types, the filter searches for matches in the InLineResult attribute. Those values could be Allowed, Blocked, Trusted.

  • For malware event types, the filter searches for matches in the FileAction attribute. Those values could be Cloud Lookup Timeout.

  • For syslog and NetFlow events types, the filter searches for matches in the Action attribute.

Policy

The name of the policy that triggered the event. Names will be different for ASA and FDM-managed devices.

Change the Time Zone for the Event Timestamps

Change the time zone display for event timestamps on the Security Cloud Control Event Logging page.

Procedure

Step 1

From the Security Cloud Control home page, choose Products > Firewall.

Step 2

From the left pane, choose Events & Logs > Events > Event Logging.

Step 3

Click the UTC Time or Local Time button on the top right side of the Event Logging page to display the event timestamps in the selected time zone.

By default, event timestamps are displayed in your local time zone.

Customizable Event Filters

If you are a Secure Logging Analytics (SaaS) customer, you can create and save custom filters that you use frequently.

The elements of your filter are saved to a filter tab as you configure them. Whenever you return to the Event Logging page, these searches will be available to you. They will not be available to other Security Cloud Control users of the tenant. They will not be available to you on a different tenant, if you manage more than one tenant.


Note

Be aware that when you are working in a filter tab, if you modify any filter criteria, those changes are saved to your custom filter tab automatically.

Procedure

Step 1

From the Security Cloud Control home page, choose Products > Firewall.

Step 2

From the main menu, choose Events & Logs > Events > Event Logging.

Step 3

Clear the Search field of any values.

Step 4

Above the event table, click the blue plus button to add a View tab. Filter views are labeled "View 1", "View 2", "View 3" and so on until you give them a name.

Step 5

Select a view tab.

Step 6

Open the filter bar and select the filters attributes you want in your custom filter. See Search and Filter Events Using the Event Logging Page. Remember that only filter attributes are saved in the custom filter.

Step 7

Customize the columns you want to show in the event logging table. See Show and Hide Columns on the Event Logging Page for a discussion of showing and hiding columns.

Step 8

Double-click the filter tab with the "View X" label and rename it.

Step 9

(Optional) Now that you have created a custom filter, you can fine tune the results displayed on the Event Logging page, without changing the custom filter, by adding search criteria to the Search field. See Search and Filter Events Using the Event Logging Page.

Search and Filter Events Using the Event Logging Page

Searching and filtering the historical and live event tables for specific events, works the same way as it does when searching and filtering for other information in Security Cloud Control. As you add filter criteria, Security Cloud Control starts to limit what it displays on the Event Logging page. You can also enter search criteria in the search field to find events with specific values. If you combine the filtering and searching mechanisms, search tries to find the value you entered from among the results displayed after filtering the events.

Following are the options to conduct a search for event logs:

Filtering works the same way for live events as it does for historical events with the exception that live events cannot be filtered by time.

Learn about these filtering methods:

Filter Live or Historical Events

This procedure explains how to use event filtering to see a subset of events in the Event Logging page. If you find yourself repeatedly using certain filter criteria, you can create a customized filter and save it. See Customizable Event Filters for more information.

Procedure

Step 1

From the Security Cloud Control home page, choose Products > Firewall.

Step 2

In the navigation bar, choose Events & Logs > Events > Event Logging

Step 3

Click either the Historical or Live tab.

Step 4

Click the filter icon (). Click the pin icon () to pin the Filter pane and keep it open.

Step 5

Click a view tab that has no saved filter elements.

Step 6

Select the event details you want to filter by:

  • FTD Events:

    • Connection: Displays connection events from access control rules.

    • File: Displays events reported by file policies in access control rules.

    • Intrusion: Displays events reported by intrusion policy in access control rules.

    • Malware: Displays events reported by malware policies in access control rules.

  • ASA Events: These event types represent groups of syslog or NetFlow events.

    See Security Cloud Control Event Types for more information about events.

  • Time Range: Click the Start or End time fields to select the beginning and end of the time period you want to display. The time stamp is displayed in the local time of your computer.

  • Action: Specifies the security action defined by the rule. The value you enter must be an exact match to what you want to find; however, the case doesn't matter. Enter different values for connection, file, intrusion, malware, syslog, and NetFlow event types:

    • For connection event types, the filter searches for matches in the AC_RuleAction attribute. Those values could be Allow, Block, Trust.

    • For file event types, the filter searches for matches in the FileAction attribute. Those values could be Allow, Block, Trust.

    • For intrusion event types, the filter searches for matches in the InLineResult attribute. Those values could be Allowed, Blocked, Trusted.

    • For malware event types, the filter searches for matches in the FileAction attribute. Those values could be Cloud Lookup Timeout.

    • For syslog and NetFlow events types, the filter searches for matches in the Action attribute.

  • Sensor ID / Hostname: The Sensor ID is the management IP address from which events are sent to the Secure Event Connector or Security Service Exchange.

    For an FDM-managed device, the Sensor ID is typically the IP address of the device's management interface.

  • IP addresses

    • Initiator : This is the IP address of the source of the network traffic. The value of the Initiator address field corresponds to the value of the InitiatorIP field in the event details. You can enter a single address, such as 10.10.10.100, or a network defined in CIDR notation such as 10.10.10.0/24.

    • Responder: This is the destination IP address of the packet. The value of the Destination address field corresponds to the value in the ResponderIP field in the event details. You can enter a single address, such as 10.10.10.100, or a network defined in CIDR notation such as 10.10.10.0/24.

  • Ports

    • Initiator: The port or ICMP type used by the session initiator. The value of the source port corresponds to the value fo the InitiatorPort in the event details. (Add a range - starting port ending port and space in between or both initiator and responder)

    • Reponder: The port or ICMP code used by the session responder. The value of the destination port corresponds to the value of the ResponderPort in the event details.

Step 7

(Optional) Save your filter as a custom filter by clicking out of the view tab.

Filter for ASA or FDM-Managed Device Syslog Events but not ASA NetFlow Events

This procedure finds only syslog events:

Procedure

Step 1

From the Security Cloud Control home page, choose Products > Firewall.

Step 2

In the left pane, choose Events & Logs > Events > Event Logging.

Step 3

Click the Filter icon and pin the filter open.

Step 4

Scroll to the bottom of the Filter pane and make sure the Include NetFlow events filter is unchecked.

Step 5

Scroll back up to the ASA Events filter tree, and make sure the NetFlow box is unchecked.

Step 6

Select the rest of your ASA or FTD filter criteria.

Combine Filter Elements

Filtering events generally follows the standard filtering rules in Security Cloud Control: The filtering categories are "AND-ed" and the values within the categories are "OR-ed." You can also combine the filter with your own search criteria. In the case of event filters; however, the device event filters are also "OR-ed." For example, if these values were chosen in the filter:

With this filter in use, Security Cloud Control would display Firewall Threat Defense device connection events or ASA BotNet or Firewall Traffic events, and those events that occurred between the two times in the time range, and those events that also contain the ResponderPort 443. You can filter by historical events within a time range. The live events page always displays the most recent events.

Search for Specific Attribute: Value Pairs

You can search for live or historical events by entering an event attribute and a value in the search field. The easiest way to do this is to click the attribute in the Event Logging table that you want to search for, and Security Cloud Control enters it in the Search field. The events you can click on will be blue when you roll over them. Here is an example:

In this example, the search started by rolling over the InitiatorIP value of 10.10.11.11 and clicking it. Initiator IP and it's value were added to the search string. Next, Event Type, 3 was rolled-over and clicked and added to the search string and an AND was added by Security Cloud Control. So the result of this search will be a list of events that were initiated from 10.10.11.11 AND that are 3 event types.

Notice the magnifying glass next to the value 3 in the example above. If you roll-over the magnifying glass, you could also choose an AND, OR, AND NOT, OR NOT operator to go with the value you want to add to the search.

In the example below, "OR" is chosen. The result of this search will be a list of events that were initiated from 10.10.11.11 OR are a 106023 event type. Note that if the search field is empty and you right click a value from the table, only NOT is available as there is no other value.

As long as you rollover a value and it is highlighted blue, you can add that value to the search string.

AND, OR, NOT, AND NOT, OR NOT Filter Operators

Here are the behaviors of "AND", "OR", "NOT", "AND NOT", and "OR NOT" used in a search string:

AND

Use the AND operator in the filter string, to find events that include all attributes. The AND operator cannot begin a search string.

For example, the search string below will search for events that contain the TCP protocol AND that originated from InitiatorIP address 10.10.10.43, AND that were sent from the Initiator port 59614. One would expect that with each additional AND statement, the number of events that meet the criteria would be small and smaller. 

Protocol: "tcp" AND InitiatorIP: "10.10.10.43" AND InitiatorPort: "59614"

OR

Use the OR operator in the filter string, to find events that include any of the attributes. The OR operator cannot begin a search string.

For example, the search string below will display events in the event viewer that include events that include the TCP protocol, OR that originated from InitiatorIP address 10.10.10.43, OR that were sent from the Initiator port 59614. One would expect that with each additional OR statement, the number of events that meet the criteria would be bigger and bigger. 

Protocol: "tcp" OR InitiatorIP: "10.10.10.43" OR InitiatorPort: "59614"

NOT

Use this only at the beginning of a search string to exclude events with certain attribtues. For example, this search string would exclude any event with the InitiatorIP 192.168.25.3 from the results. 

 NOT InitiatorIP: "192.168.25.3"

AND NOT

Use the AND NOT operator in the filter string to exclude events that contain certain attributes. AND NOT cannot be used at the beginning of a search string.

For example, this filter string will display events with the InitiatorIP 192.168.25.3 but not those whose ResponderIP address is also 10.10.10.1. 

 InitiatorIP: "192.168.25.3" AND NOT ResponderIP: "10.10.10.1"

You can also combine NOT and AND NOT to exclude several attributes. For example this filter string, will exclude events with InitiatorIP 192.168.25.3 and events with ResponderIP 10.10.10.1 

NOT InitiatorIP: "192.168.25.3" AND NOT ResponderIP: "10.10.10.1"

OR NOT

Use the OR NOT operator to include search results that exclude certain elements. The OR NOT operator cannot be used at the beginning of a search string.

For example, this search string will find events with the Protocol of TCP, OR that have the InitiatorIP of 10.10.10.43, or those NOT from InitiatorPort 59614. 

Protocol: "tcp" OR InitiatorIP: "10.10.10.43" OR NOT InitiatorPort: "59614"

You could also think of it this way: Search for (Protocol: "tcp") OR (InitiatorIP: "10.10.10.43") OR (NOT InitiatorPort: "59614").

Wildcard Searches

Use an asterisk (*) to represent a wildcard in the value field of an attribute:value search to find results within events. For example, this filter string, 

 URL:*feedback*

will find strings in the URL attribute field of events that contain the string feedback.

Search Events Using the Events Logging Page

Event Attributes in Security Analytics and Logging

Event Attribute Descriptions

The event attribute descriptions used by Security Cloud Control are largely the same as what is reported by Firepower Device Manager (FDM) and Adaptive Security Device Manager (ASDM).

Some ASA syslog events are "parsed" and others have additional attributes which you can use when filtering the contents of the Event Logging table using attribute:value pairs. See these additional topics for other important attributes of syslog events:

EventGroup and EventGroupDefinition Attributes for Some Syslog Messages

Some syslog events will have the additional attributes "EventGroup" and "EventGroupDefinition". You will be able to filter the events table to find events using these additional attributes by filtering by attribute:value pairs. For example, you could filter for Application Firewall events by entering apfw:415* in the search field of the Event Logging table.

EventName Attributes for Syslog Events

Some syslog events will have the additional attribute "EventName". You will be able to filter the events table to find events using the EventName attribute by filtering by attribute:value pairs. For example, you could filter events for a "Denied IP packet" by entering EventName:"Denied IP Packet" in the search field of the Event Logging table.

Time Attributes in a Syslog Event

Understanding the purposes of the different time-stamps in the Event Logging page will help you filter and find the events that interest you.

Number

Label

Description

1

Date/Time

The time the Secure Event Connector (SEC) processed the event. This may not be the same as the time the firewall inspected that traffic. Same value as timestamp.

2

EventSecond

Equals with LastPacketSecond.

3

FirstPacketSecond

The time at which the connection opened. The firewall inspects the packet at this time.

The value of the FirstPacketSecond is calculated by subtracting the ConnectionDuration from the LastPacketSecond.

For connection events logged at the beginning of the connection, the value of FirstPacketSecond, LastPacketSecond, and EventSecond will all be the same.

4

LastPacketSecond

The time at which the connection closed. For connection events logged at the end of the connection, LastPacketSecond and EventSecond will be equal.

5

timestamp

The time the Secure Event Connector (SEC) processed the event. This may not be the same as the time the firewall inspected that traffic. Same value as Date/Time.

6

Syslog TimeStamp

Represents the syslog originated time if ‘logging timestamp’ is used. If the syslog does not have this info, the time the SEC received the event is reflected.

7

NetflowTimeStamp

The time at which the ASA finished gathering enough flow records/events to fill a NetFlow packet to then send them off to a flow collector.

Use Cisco Secure Cloud Analytics Portal

This chapter provides information about Cisco Secure Cloud Analytics portal.

Provision a Cisco Secure Cloud Analytics Portal

Required License: Logging Analytics and Detection or Total Network Analytics and Monitoring

If you purchase a Logging Analytics and Detection or Total Network Analytics and Monitoring license, after you deploy and configure the Secure Event Connector (SEC), you must associate a Secure Cloud Analytics portal with your Security Cloud Control portal to view Secure Cloud Analytics alerts. When you purchase the license, if you have an existing Secure Cloud Analytics portal, you can provide the Secure Cloud Analytics portal name and immediately link it to your Security Cloud Control portal.

Otherwise, you can request a new Secure Cloud Analytics portal from the Security Cloud Control UI. The first time you access Secure Cloud Analytics alerts, the system takes you to a page to request the Secure Cloud Analytics portal. The user that requests this portal is granted administrator permission in the portal.

Procedure

Step 1

In the left pane, click Analytics > Secure Cloud Analytics to open the Secure Cloud Analytics UI in a new window.

Step 2

Click Start Free Trial to provision a Secure Cloud Analytics portal and associate it with your Security Cloud Control portal.

Note

 

After you request the portal, the provisioning may take up to several hours.

Ensure that your portal is provisioned before moving on to the next step.

  1. In the left pane, click Analytics > Secure Cloud Analytics to open the Secure Cloud Analytis UI in a new window.

  2. You have the following options:

    • If you requested a Secure Cloud Analytics portal, and the system states it is still provisioning the portal, wait and try to access the alerts later.

    • If the Secure Cloud Analytics portal is provisioned, enter your Username and Password, then click Sign in.


Note

The administrator user can invite other users to create accounts within the Secure Cloud Analytis portal. See Viewing Cisco Secure Cloud Analytics Alerts from Security Cloud Control for more information.

Sensor Status

Required License: Logging Analytics and Detection or Total Network Analytics and Monitoring

In the Secure Cloud Analytis web UI, you can view your Security Cloud Control integration status and your configured sensors from the Sensor List page. The Security Cloud Control integration is the read-only connection-events sensor. Stelathwatch Cloud provides an overall health of your sensors in the main menu:

  • green cloud icon () - connectivity established with all sensors, and Security Cloud Control if configured

  • yellow cloud icon () - connectivity established with some sensors, or Security Cloud Control if configured, and one or more sensors is not configured properly

  • red cloud icon () - connectivity lost with all configured sensors, and Security Cloud Control if configured

Per sensor or Security Cloud Control integration, a green icon signifies connectivity established, and a red icon signifies connectivity lost.

Procedure

Step 1

1. In the Secure Cloud Analytis portal UI, select Settings () > Sensors.

Step 2

Select Sensor List.

Cisco Secure Cloud Analytics Sensor Deployment for Total Network Analytics and Reporting

Secure Cloud Analytics Sensor Overview and Deployment

Required License: Total Network Analytics and Monitoring

If you obtain a Total Network Analytics and Monitoring license, after you provision a Secure Cloud Analytics portal, you can:

  • Deploy and configure a Secure Cloud Analytics sensor within your on-premises network to pass network flow data to the cloud for analysis.

  • Configure your cloud-based deployment to pass network flow log data to Secure Cloud Analytics for analysis.

Firewalls at your network perimeter gather information about traffic between your internal network and external networks, while Secure Cloud Analytics sensors gather information about traffic within your internal network.


Note

FDM-managedSecure Firewall Threat Defense devices may be configured to pass NetFlow data. When you deploy a sensor, do not configure it to pass NetFlow data from any of your FDM-managedSecure Firewall Threat Defense devices which you also configured to pass event information to Security Cloud Control.

See the Secure Cloud Analytics Sensor Installation Guide for sensor deployment instructions and recommendations.

See the Secure Cloud Analytics Public Cloud Monitoring Guides for cloud-based deployment configuration instructions and recommendations.


Note

You can also review instructions in the Secure Cloud Analytics portal UI to configure sensors and your cloud-based deployment.

See the Secure Cloud Analytics Free Trial Guide for more information about Secure Cloud Analytics.

Next Steps

Viewing Cisco Secure Cloud Analytics Alerts from Security Cloud Control

Required License: Logging Analytics and Detection or Total Network Analytics and Monitoring

While you can review your firewall events on the Events logging page, you cannot review Cisco Secure Cloud Analytics alerts from the Security Cloud Control portal UI. You can cross-launch from Security Cloud Control to the Secure Cloud Analytics portal using the Security Analytics menu option, and view alerts generated from firewall event data (and from network flow data if you enabled Total Network Analytics and Monitoring). The Security Analytics menu option displays a badge with the number of Secure Cloud Analytics alerts in an open workflow status, if 1 or more are open.

If you use a Security Analytics and Logging license to generate Secure Cloud Analytics alerts, and you provisioned a new Secure Cloud Analytics portal, log into Security Cloud Control, then cross-launch to Secure Cloud Analytics using Cisco Security Cloud Sign On. You can also directly access your Secure Cloud Analytics portal through its URL.

See Cisco Security Cloud Sign On for more information.

Inviting Users to Join Your Secure Cloud Analytics Portal

The initial user to request the Secure Cloud Analytics portal provision has administrator privileges in the Secure Cloud Analytics portal. That user can invite other users by email to join the portal. If these users do not have Cisco Security Cloud Sign On credentials, they can create them using the link in the invite email. Users can then use Cisco Security Cloud Sign On credentials to log in during the cross-launch from Security Cloud Control to Secure Cloud Analytics.

To invite other users to your Secure Cloud Analytics portal by email:

Procedure

Step 1

Log into your Secure Cloud Analytics portal as an administrator.

Step 2

Select Settings > Account Management > User Management.

Step 3

Enter an Email address.

Step 4

Click Invite.

Cross-Launching from Security Cloud Control to Secure Cloud Analytics

To view security alerts from Security Cloud Control:

Procedure

Step 1

Log into the Security Cloud Control portal.

Step 2

In the left pane, choose Analytics > Secure Cloud Analytics.

Step 3

In the Secure Cloud Analytics interface, select Monitor > Alerts.

Cisco Secure Cloud Analytics and Dynamic Entity Modeling

Required License: Logging Analytics and Detection or Total Network Analytics and Monitoring

Secure Cloud Analytics is a software as a service (SaaS) solution that monitors your on-premises and cloud-based network deployments. By gathering information about your network traffic from sources including firewall events and network flow data, it creates observations about the traffic and automatically identifies roles for network entities based on their traffic patterns. Using this information combined with other sources of threat intelligence, such as Talos, Secure Cloud Analytics generates alerts, which constitute a warning that there is behavior that may be malicious in nature. Along with the alerts, Secure Cloud Analytics provides network and host visibility, and contextual information it has gathered to provide you with a better basis to research the alert and locate sources of malicious behavior.

Dynamic Entity Modeling

Dynamic entity modeling tracks the state of your network by performing a behavioral analysis on firewall events and network flow data. In the context of Secure Cloud Analytics, an entity is something that can be tracked over time, such as a host or endpoint on your network. Dynamic entity modeling gathers information about entities based on the traffic they transmit and activities they take on your network. Secure Cloud Analytics, integrated with a Logging Analytics and Detection license, can draw from firewall events and other traffic information in order to determine the types of traffic the entity usually transmits. If you purchase a Total Network Analytics and Monitoring license, Secure Cloud Analytics can also include NetFlow and other traffic information in modeling entity traffic. Secure Cloud Analytics updates these models over time, as the entities continue to send traffic, and potentially send different traffic, to keep an up-to-date model of each entity. From this information, Secure Cloud Analytics identifies:

  • Roles for the entity, which are a descriptor of what the entity usually does. For example, if an entity sends traffic that is generally associated with email servers, Secure Cloud Analytics assigns the entity an Email Server role. The role/entity relationship can be many-to-one, as entities may perform multiple roles.

  • Observations for the entity, which are facts about the entity's behavior on the network, such as a heartbeat connection with an external IP address, or a remote access session established with another entity. If you integrate with Security Cloud Control, these facts can be obtained from firewall events. If you also purchase a Total Network Analytics and Monitoring, license, the system can also obtain facts from NetFlow, and generate observations from both firewall events and NetFlow. Observations on their own do not carry meaning beyond the fact of what they represent. A typical customer may have many thousands of observations and a few alerts.

Alerts and Analysis

Based on the combination of roles, observations, and other threat intelligence, Secure Cloud Analytics generates alerts, which are actionable items that represent possible malicious behavior as identified by the system. Note that one alert may represent multiple observations. If a firewall logs multiple connection events related to the same connection and entities, this may result in only one alert.

For example, a New Internal Device observation on its own does not constitute possible malicious behavior. However, over time, if the entity transmits traffic consistent with a Domain Controller, then the system assigns a Domain Controller role to the entity. If the entity subsequently establishes a connection to an external server that it has not established a connection with previously, using unusual ports, and transfers large amounts of data, the system would log a New Large Connection (External) observation and an Exceptional Domain Controller observation. If that external server is identified as on a Talos watchlist, then the combination of all this information would lead Secure Cloud Analytics to generate an alert for this entity's behavior, prompting you to take further action to research, and remediate malicious behavior.

When you open an alert in the Secure Cloud Analytics web portal UI, you can view the supporting observations that led the system to generate the alert. From these observations, you can also view additional context about the entities involved, including the traffic that they transmitted, and external threat intelligence if it is available. You can also see other observations and alerts that entities were involved with, and determine if this behavior is tied to other potentially malicious behavior.

Note that when you view and close alerts in Secure Cloud Analytics, you cannot allow or block traffic from the Secure Cloud Analytics UI. You must update your firewall access control rules to allow or block traffic, if you deployed your devices in active mode, or your firewall access control rules if your firewalls are deployed in passive mode.

Working with Alerts Based on Firewall Events

Required License: Logging Analytics and Detection or Total Network Analytics and Monitoring

Alerts Workflow

An alert's workflow is based around its status. When the system generates an alert, the default status is Open, and no user is assigned. When you view the Alerts summary, all open alerts are displayed by default, as these are of immediate concern.

Note: If you have a Total Network Analytics and Monitoring license, your alerts can be based on observations generated from NetFlow, observations generated from firewall events, or observations from both data sources.

As you review the Alerts summary, you can assign, tag, and update status on alerts as an initial triage. You can use the filters and search functionality to locate specific alerts, or display alerts of different statuses, or associated with different tags or assignees. You can set an alert's status to Snoozed, in which case it does not reappear in the list of open alerts until the snooze period elapses. You can also remove Snoozed status from an alert, to display it as an open alert again. As you review alerts, you can assign them to yourself or another user in the system. Users can search for all alerts assigned to their username.

From the Alerts summary, you can view an alert detail page. This page allows you to review additional context about the supporting observations that resulted in this alert, and additional context about the entities involved in this alert. This information can help you pinpoint the actual issue, in order to further research the issue on your network, and potentially resolve malicious behavior.

As you research within the Secure Cloud Analytics web portal UI, in Security Cloud Control, and on your network, you can leave comments with the alert that describe your findings. This helps create a record for your research that you can reference in the future.

If you complete your analysis, you can update the status to Closed, and have it no longer appear by default as an open alert. You can also re-open a closed alert in the future if circumstances change.

The following presents general guidelines and suggestions for how to investigate a given alert. Because Secure Cloud Analytics provides additional context when it logs an alert, you can use this context to help guide your investigation.

These steps are meant to be neither comprehensive, nor all-inclusive. They merely offer a general framework with which to start investigating an alert.

In general, you can take the following steps when you review an alert:

  1. Triage open alerts

  2. Snooze alerts for later analysis

  3. Update the alert for further investigation

  4. Review the alert and start your investigation

  5. Examine the entity and users

  6. Remediate issues using Secure Cloud Analytics

  7. Update and close the alert

Triage open alerts

Triage the open alerts, especially if more than one have yet to be investigated:

Ask the following questions:

  • Have you configured this alert type as high priority?

  • Did you set a high sensitivity for the affected subnet?

  • Is this unusual behavior from a new entity on your network?

  • What is the entity's normal role, and how does the behavior in this alert fit that role?

  • Is this an exceptional deviation from normal behavior for this entity?

  • If a user is involved, is this expected behavior from the user, or exceptional?

  • Is protected or sensitive data at risk of being compromised?

  • How severe is the impact to your network if this behavior is allowed to continue?

  • If there is communication with external entities, have these entities established connections with other entities on your network in the past?

If this is a high priority alert, consider quarantining the entity from the internet, or otherwise closing its connections, before continuing your investigation.

Snooze alerts for later analysis

Snooze alerts when they are of lesser priority, as compared to other alerts. For example, if your organization is repurposing an email server as an FTP server, and the system generates an Emergent Profile alert (indicating that an entity's current traffic matches a behavior profile that it did not previously match), you can snooze this alert as it is intended behavior, and revisit it at a later date. A snoozed alert does not show up with the open alerts; you must specifically filter to review these snoozed alerts.

Snooze an alert:

Procedure

Step 1

Click Close Alert.

Step 2

In the Snooze this alert pane, select a snooze period from the drop-down.

Step 3

Click Save.

What to do next

When you are ready to review these alerts, you can unsnooze them. This sets the status to Open, and displays the alert alongside the other Open alerts.

Unsnooze a snoozed alert:

  • From a snoozed alert, click Unsnooze Alert.

Update the alert for further investigation

Open the alert detail:

Procedure

Step 1

Select Monitor > Alerts.

Step 2

Click an alert type name.
What to do next

Based on your initial triage and prioritization, assign the alert and tag it:

  1. Select a user from the Assignee drop-down to assign the alert, so a user can start investigating.

  2. Select one or more Tags from the drop-down to add tags to the alert, to better categorize your alert's for future identification, as well as to try and establish long-term patterns in your alerts.

  3. Enter a Comment on this alert, then click Comment to leave comments as necessary to track your initial findings, and assist the person assigned to the alert. The alert tracks both system comments and user comments.

Review the alert and start your investigation

If you are reviewing an assigned alert, review the alert detail to understand why Secure Cloud Analytics generated an alert. Review the supporting observations to understand what these observations mean for the source entity.

Note that if the alert was generated based on firewall events, the system does not note that your firewall deployment was the source of this alert.

View all of the supporting observations for this source entity to understand its general behavior and patterns, and see if this activity may be part of a longer trend:

Procedure

Step 1

From the alert detail, click the arrow icon () next to an observation type to view all logged observations of that type.

Step 2

Click the arrow icon () next to All Observations for Network to view all logged observations for this alert's source entity.

Download the supporting observations in a comma-separated value file, if you want to perform additional analysis on these observations:

  • From the alert detail, in the Supporting Observations pane, click CSV.

From the observations, determine if the source entity behavior is indicative of malicious behavior. If the source entity established connections with multiple external entities, determine if the external entities are somehow related, such as if they all have similar geolocation information, or their IP addresses are from the same subnet.

View additional context surrounding the source entity from a source entity IP address or hostname, including other alerts and observations it may be involved in, information about the device itself, and what type of session traffic it is transmitting:

  • Select Alerts from the IP address or hostname drop-down to view all alerts related to the entity.

  • Select Observations from the IP address or hostname drop-down to view all observations related to the entity.

  • Select Device from the IP address or hostname drop-down to view information about the device.

  • Select Session Traffic from the IP address or hostname drop-down to view session traffic related to this entity.

  • Select Copy from the IP address or hostname drop-down to copy the IP address or hostname.

Note that the source entity in Secure Cloud Analytics is always internal to your network. Contrast this with the Initiator IP in a firewall event, which indicates the entity that initiated a connection, and may be internal or external to your network.

From the observations, examine information about other external entities. Examine the geolocation information, and determine if any of the geolocation data or Umbrella data identifies a malicious entity. View the traffic generated by these entities. Check whether Talos, AbuseIPDB, or Google have any information on these entities. Find the IP address on multiple days and see what other types of connections the external entity established with entities on your network. If necessary, locate those internal entities and determine if there is any evidence of compromise or unintended behavior.

Review the context for an external entity IP address or hostname with which the source entity established a connection:

  • Select IP Traffic from the IP address or hostname drop-down to view recent traffic information for this entity.

  • Select Session Traffic from the IP address or hostname drop-down to view recent session traffic information for this entity.

  • Select AbuseIPDB from the IP address or hostname drop-down to view information about this entity on AbuseIPDB's website.

  • Select Cisco Umbrella from the IP address or hostname drop-down to view information about this entity on Cisco Umbrella's website.

  • Select Google Search from the IP address or hostname drop-down to search for this IP address on Google.

  • Select Talos Intelligence from the IP address or hostname drop-down to view information about this information on Talos's website.

  • Select Add IP to watchlist from the IP address or hostname drop-down to add this entity to the watchlist.

  • Select Find IP on multiple days from the IP address or hostname drop-down to search for this entity's traffic from the past month.

  • Select Copy from the IP address or hostname drop-down to copy the IP address or hostname.

Note that connected entities in Secure Cloud Analytics are always external to your network. Contrast this with the Responder IP in a firewall event, which indicates the entity that responded to a connection request, and may be internal or external to your network.

Leave comments as to your findings.

  • From the alert detail, enter a Comment on this alert, then click Comment.

Examine the entity and users

After you review the alert in the Secure Cloud Analytics portal UI, you can perform an additional examination on a source entity directly, any users that may have been involved with this alert, and other related entities.

  • Determine where the source entity is on your network, physically or in the cloud, and access it directly. Locate the log files for this entity. If it is a physical entity on your network, access the device to review the log information, and see if there is any information as to what caused this behavior. If it is a virtual entity, or stored in the cloud, access the logs and search for entries related to this entity. Examine the logs for further information on unauthorized logins, unapproved configuration changes, and the like.

  • Examine the entity. Determine if you can identify malware or a vulnerability on the entity itself. See if there has been some malicious change, including if there are physical changes to a device, such as a USB stick that is not approved by your organization.

  • Determine if a user on your network, or from outside your network, was involved. Ask the user what they were doing if possible. If the user is unavailable, determine if they were supposed to have access, and if a situation occurred that prompted this behavior, such as a terminated employee uploading files to an external server before leaving the company.

Leave comments as to your findings:

  • From the alert detail, enter a Comment on this alert, then click Comment.

Remediate issues using Secure Cloud Analytics

If malicious behavior caused the alert, remediate the malicious behavior. For example:

  • If a malicious entity or user attempted to log in from outside your network, update your firewall rules and firewall configuration to prevent the entity or user from accessing your network.

  • If an entity attempted to access an unauthorized or malicious domain, examine the affected entity to determine if malware is the cause. If there are malicious DNS redirects, determine if other entities on your network are affected, or part of a botnet. If this is intended by a user, determine if there is a legitimate reason for this, such as testing firewall settings. Update your firewall rules and firewall configuration to prevent further access to the domain.

  • If an entity is exhibiting behavior that is different from the historical entity model behavior, determine if the behavior change is intended. If it is unintended, examine whether an otherwise authorized user on your network is responsible for the change. Update your firewall rules and firewall configuration to address unintended behavior if it involves connections with entities that are external to your network.

  • If you identify a vulnerability or exploit, update or patch the affected entity to remove the vulnerability, or update your firewall configuration to prevent unauthorized access. Determine if other entities on your network may similarly be affected, and apply the same update or patch to those entities. If the vulnerability or exploit currently does not have a fix, contact the appropriate vendor to let them know.

  • If you identify malware, quarantine the entity and remove the malware. Review the firewall file and malware events to determine if other entities on your network are at risk, and quarantine and update the entities to prevent this malware from spreading. Update your security intelligence with information about this malware, or the entities that caused this malware. Update your firewall access control and file and malware rules to prevent this malware from infecting your network in the future. Alert vendors as necessary.

  • If malicious behavior resulted in data exfiltration, determine the nature of the data sent to an unauthorized source. Follow your organization's protocols for unauthorized data exfiltration. Update your firewall configuration to prevent future data exfiltration attempts by this source.

Update and close the alert

Add additional tags based on your findings:

Procedure

Step 1

In the Secure Cloud Analytics portal UI, select Monitor > Alerts.

Step 2

Select one or more Tags from the drop-down.

Add final comments describing the results of your investigation, and any remediation steps taken:

  • From an alert's detail, enter a Comment on this alert, then click Comment.

Close the alert, and mark it as helpful or not helpful:

  1. From an alert's detail, click Close Alert.

  2. Select Yes if the alert was helpful, or No if the alert was unhelpful. Note that this does not necessarily mean that the alert resulted from malicious behavior, just that the alert was helpful to your organization.

  3. Click Save.

What to do next

Reopen a closed alert

If you discover additional information related to a closed alert, or want to add more comments related to that alert, you can reopen it, changing the status to Open. You can then make changes as necessary to the alert, then close it again when your additional investigation is complete.

Reopen a closed alert:

  • From a closed alert's detail, click Reopen Alert.

Modifying Alert Priorities

Required License: Logging Analytics and Detection or Total Network Analytics and Monitoring

Alert types come with default priorities, which affect how sensitive the system is to generating alerts of this type. Alerts default to low or normal priority, based on Cisco intelligence and other factors. Based on your network environment, you may want to reprioritize alert types, to emphasize certain alerts that you are concerned with. You can configure any alert type to be low, normal, or high priority.

  • Select Monitor > Alerts.

  • Click the settings drop-down icon (), then select Alert Types and Priorities.

  • Click the edit icon () next to an alert type and select low, medium, or high to change the priority.
