New Features and Functionality

This section of the release notes summarizes the new and updated features and functionality included in Version 6.0 of the Firepower System:

- New Features

- Changed Functionality

- Updated Terminology

- Updated Documentation

New Features

The following features are introduced in Version 6.0:

Expanded Threat Protection

URL and DNS-based Security Intelligence

New Security Intelligence feeds based on URLs and Domain Name System (DNS) servers are provided to enhance the existing IP-based Security Intelligence capability. Currently, IP-based intelligence is used to control access to known malware, phishing, command & control, and Bot sites. New attack methods designed to defeat IP-based intelligence (e.g., fast flux) abuse DNS load balancing features in an effort to hide the actual IP address of a malicious server. While the IP addresses associated with the attack are frequently swapped in and out, the domain name will rarely change. The URL-based intelligence will supplement the IP-based intelligence in addressing this kind of attack, and the DNS-based intelligence will help identify known DNS servers that are complicit in these kinds of attacks. Access control policies can be created using these new intelligence feeds and new dashboards provide visibility and analysis. In addition, both URL-based and DNS-based Security Intelligence events will also feed in to the Indications of Compromise (IoC) correlation feature. These new feeds are provided through regular updates from the Cisco Talos Security Intelligence and Research Group and, like the IP-based Security Intelligence feature, are part of the base product and do not require a separate license.

DNS Inspection and Sinkholes

The same way that attackers use the SSL protocol to hide their activity, attackers use the DNS protocol with the same intentions. For that reason, and as another way to address fast flux-type attacks, the Firepower system provides the ability to intercept DNS traffic requests and take appropriate action based on the policy setting. A DNS policy allows for requests to known command & control, spam, phishing, etc., sites to be blocked, to return a Domain Not Found message, or have the traffic directed to a pre-configured sinkhole. This last option routes the traffic directly through the Firepower managed device and gives information about the endpoint that could result in an IoC alert.

Enhanced Network Visibility and Control

SSL Decryption for Cisco ASA with FirePOWER Services Managed Via ASDM

Cisco’s next-generation firewall (NGFW), Cisco ASA with FirePOWER Services, now has the ability to locally manage SSL communications and decrypt the traffic before performing attack, application, and malware detection against it. This is the same capability we introduced in Version 5.4 for Cisco’s Firepower next-generation IPS (NGIPS) appliances. SSL decryption can be deployed in both passive and inline modes, and supports HTTPS and StartTLS-based applications (e.g., SMTPS, POP3S, FTPS, IMAPS, TelnetS). Decryption policies can be configured to exert granular control over encrypted traffic logging and handling, such as limiting decryption based on URL categories to enforce privacy concerns. It also provides the ability to block self-signed encrypted traffic, or on SSL version, specific Cipher Suites, and/or unapproved mobile devices.

Support for OpenAppID-Defined Applications

OpenAppID is Cisco’s open source, application-focused detection language that enables users to create, share and implement new application detection signatures for custom, localized, and cloud applications, without being dependent upon a NGFW vendor’s release cycle or roadmap. In Version 6.0, the Firepower application detection engine that identifies and controls access to over 3,000 applications has been enhanced to recognize OpenAppID-defined applications. In the same way that Snort was an effort to open source the intrusion detection game, OpenAppID is a way to open source the application detection game. Support for OpenAppId-defined applications demonstrates Cisco’s commitment to the open source initiatives and the flexibility that it provides to our customers.

Captive Portal and Active Authentication

In order to provide better visibility in mapping users to IP addresses and their associated network events, the Captive Portal and Active Authentication feature can be configured to require users to enter their credentials when prompted through a browser window. The mapping also allows policies to be based on a user or group of users. This feature supplements the existing Sourcefire User Agent (SUA) integration with Active Directory to address non-Windows environments, BYOD users, and guests.

Note: Cisco ASA with FirePOWER Services only supports the Captive Portal and Active Authentication feature when running ASA version 9.5(2) or later.

Integration with Cisco Identity Services Engine (ISE)

The integration with Cisco ISE enhances the user identity data available to the system to use in analysis and policy control. By subscribing to Cisco’s Platform Exchange Grid (PxGrid), the Firepower Management Center is able to download additional user data, device type data, device location data, and Security Group Tags (SGTs —a method used by ISE to provide network access control). Beyond the added visibility into the users on your network, this data is also actionable intelligence because it extends the control you can provide by creating policies based on SGTs, or on device type, or any of the other information provided by ISE.

Note: In Version 6.0, you cannot use ISE to automatically quarantine an infected endpoint. This functionality will be added in a later release.

Improved Threat Defense Against Advanced Persistent Threats

Local Malware Checks

This feature provides the ability to identify popular/common malware directly on the Firepower appliance, and reduces the need to send files for dynamic analysis (sandboxing), either in the cloud or on-prem (see Intergration with AMP Threat Grid). Using high-fidelity ClamAV signatures, files whose SHA-256 lookup return a disposition of Unknown will be analyzed locally on the Firepower appliance to identify common characteristics associated with malware, reducing the need for dynamic analysis.

File Property Analysis

Because certain file types support nested content that can be used to hide malware, this feature provides local analysis of files to determine the viability of malware hidden within. For example, a PDF file can contain different types of files nested inside the file. A file composition report is then run that identifies if nested data exists within the file, what file types those nested files represent, and how likely each nested file is to contain malware. Based on this information, you can choose whether or not to send the file on for dynamic analysis.

Integration with AMP Threat Grid

Cisco’s acquisition of ThreatGrid in June 2014 increased our abilities in helping our customers address advanced persistent threats, and that technology has now been fully integrated in Firepower v6.0. AMP Threat Grid now provides our sandboxing capabilities in the cloud when using our AMP for Firepower option. Files sent to the cloud for dynamic analysis are securely analyzed and correlated against hundreds of millions of other analyzed malware artifacts to provide a global view of malware attacks, campaigns, and their distribution. Detailed reports identify key behavioral indicators and determine threat scores for faster prioritization and recovery from advanced attacks.

In addition, we have greatly expanded the file types we support for automatic dynamic analysis from just executable files to include PDF and Office documents.

Expanded Management Functionality

Multiple Domain Management

To address the service provider market which must manage separate customer environments, as well as enterprises with acquisitions (resulting in overlapping IP addresses) or geographic business units that need to be managed separately, the Firepower Management Center now has the ability to create multiple management domains. These domains (up to 50) enable separate management environments and are administered using granular role-based access control (RBAC). Each domain provides separate event data, reporting, and network maps.

Policy Hierarchy and Inheritance

To support multiple domain management and make policy administration more efficient, Version 6.0 provides the ability to create a hierarchy of policies. Global policies (e.g., access control) can be established that will apply to all management environments. A policy hierarchy can then be constructed underneath the global policy level to represent different environments, different companies, different business units, or different parts of the organization. Each of these policy environments will inherit the policies of the hierarchy above it, allowing for more consistent and efficient policy management.

Expanded ASDM Management Availability

Cisco’s Adaptive Security Device Manager (ASDM) is the local management feature for Cisco ASA with FirePOWER Services. It was introduced as part of the Cisco ASA 5506-X, ASA 5508-X, and ASA 5516-X appliances. With Firepower v6.0, ASDM is now available on the remaining Cisco ASA with FirePOWER Services appliances (ASA 5512-X / ASA 5515-X / ASA 5525-X / ASA 5545-X / ASA 5555-X / ASA 5585-X).

Changed Functionality

- The default password for Firepower Management Center and Firepower Management Center virtual appliances changes from Sourcefire to Admin123 in Version 6.0 and later. For more information, see the Firepower Management Center Quick Start Guide.

- You cannot compare policies on the following pages: the NAT Policy page, the Platform Settings page, and the SSL Policy page.

- Version 6.0 does not support AMP for Firepower signature lookups with the private AMP cloud. In Version 6.0, the system automatically submits SHA-256 signatures to the public AMP cloud. If you have a private AMP cloud and are receiving events from endpoints, the Version 6.0 Firepower Management Center will continue to receive those events without any additional changes to your configuration.

- Syslog messages for connection events now populate information for the following fields: HTTP Referrer, User Agent, and Referenced Host.

- Version 6.0 does not support Discovery Event Health Monitoring.)

- You can now edit Automatic Application Bypass (AAB) settings on ASA modules running FirePOWER services.

Updated Terminology

The terminology used in Version 6.0 may differ from the terminology used in previous releases. For more information, see the Firepower Compatibility Guide.

Updated Documentation

To access the full documentation for the Firepower System, see the documentation roadmap at http://www.cisco.com/c/en/us/td/docs/security/firesight/roadmap/firesight-roadmap.html.

- The online help incorrectly states that the default intrusion policy instead of the currently deployed access control policy inspects traffic during policy deployment if you deploy your configuration changes with Inspect traffic during policy apply enabled and no specific configuration requires a snort restart.

content is updated more regularly than the online help.

Before You Begin: Important Update and Compatibility Notes

Before you begin the update process for Version 6.0, you should familiarize yourself with the behavior of the system during the update process, as well as with any compatibility issues or required pre- or post-update configuration changes.

.
recommends you perform the update in a maintenance window or at a time when the interruption will have the least impact on your deployment.

Configuration and Event Backup Guidelines

Before you begin the update, Cisco strongly recommends that you delete or move any backup files that reside on your appliance, then back up current event and configuration data to an external location.

Use the Firepower Management Center to back up event and configuration data for itself and the devices it manages. For more information on the backup and restore feature, see the Firepower Management Center Configuration Guide.

Version 6.0 does not support AMP for Firepower signature lookups with the private AMP cloud. In Version 6.0, the system automatically submits SHA-256 signatures to the public AMP cloud. If you have a private AMP cloud and are receiving events from endpoints, the Version 6.0 Firepower Management Center will continue to receive those events without any additional changes to your configuration.

Note: The Firepower Management Center purges locally stored backups from previous updates. To retain archived backups, store the backups externally.

Applying the Version 6.0 Pre-Installation Package

Apply the Version 6.0 Pre-Installation Package before updating to Version 6.0 if your appliances are running the following versions:

- Firepower Management Centers running Version 5.4.1.1, Version 5.4.1.2, Version 5.4.1.3, Version 5.4.1.4, or Version 5.4.1.5

- Series 3 devices running Version 5.4.0.2, Version 5.4.0.3, Version 5.4.0.4, Version 5.4.0.5, or Version 5.4.0.6

- ASA FirePOWER modules (ASA FirePOWER modules (ASA 5512-X, ASA 5515-X, ASA 5525-X, ASA 5545-X, ASA 5555-X, ASA 5585-X-SSP-10, ASA 5585-X-SSP-20, ASA 5585-X-SSP-40, and the ASA 5585-X-SSP-60) running Version 5.4.0.2, Version 5.4.0.3, Version 5.4.0.4, Version 5.4.0.5, or Version 5.4.0.6

- ASA FirePOWER modules (ASA 5506-X, ASA 5506W-X, ASA 5506H-X, ASA 5508-X, and ASA 5516-X) running Version 5.4.1.1, Version 5.4.1.2, Version 5.4.1.3, Version 5.4.1.4, or Version 5.4.1.

Applying the Version 6.0 Pre-Installation Package before updating to Version 6.0 is not required for appliances running the following versions, but we strongly recommend applying the Version 6.0 Pre-Installation Package as it optimizes updating Firepower Management Centers to Version 6.0.0 and decreases the time the update takes to complete:

- Firepower Management Centers running Version 5.4.1.6 or later (not required, but strongly recommended)

- Series 3 devices running Version 5.4.0.7 or later

- ASA FirePOWER modules (ASA FirePOWER modules (ASA 5512-X, ASA 5515-X, ASA 5525-X, ASA 5545-X, ASA 5555-X, ASA 5585-X-SSP-10, ASA 5585-X-SSP-20, ASA 5585-X-SSP-40, and the ASA 5585-X-SSP-60) running Version 5.4.0.7 or later

- ASA FirePOWER modules (ASA 5506-X, ASA 5506W-X, ASA 5506H-X, ASA 5508-X, and ASA 5516-X) running Version 5.4.1.6 or later

Break Firepower Management Center High Availability Prior to Upgrade

Version 6.0 does not support Firepower Management Centers in a high availability pair. In order to update Firepower Management Centers in a high availability environment, you must break the pair and update each Firepower Management Center individually. In order to update to Version 6.0, you must break the high availability pair.

Update Firepower Management Center Memory for MC750 and MC1500 and Management Centers Virtual

Version 6.0 of the Firepower requires more memory than the previous versions for some Firepower Management Center models (previously referred to as the FireSIGHT Management Center or the Defense Center). To be specific, MC750 requires two 4GB dual in-line memory modules (DIMM). Similarly, MC1500 with 6GB of memory also requires additional memory.

Because the increase in memory was driven by Cisco product requirements, Cisco is making memory upgrade kits available for customers with these models. These kits can be ordered at no cost by customers who are entitled to run Version 6.0 on a qualifying MC750 or MC1500 Firepower Management Center model.

For more information on ordering memory kits, see http://www.cisco.com/c/en/us/support/docs/field-notices/640/fn64077.html. For instructions on replacing the memory after you receive the kit, see “Memory Upgrade Instructions for Firepower Management Centers” in the Firepower Management Center Installation Guide.

In addition, Management Centers Virtual require a minimum of 8GB of memory to update to Version 6.0.

Update Management Center HTTPS Certificates to Version 6.0

Use of a certificate with an RSASSA-PSS signature algorithm on a Firepower Management Center is not currently supported in Version 6.0. If you update a Firepower Management Center using such a certificate to Version 6.0 or add such a certificate in Version 6.0, the system does not allow you to log into the Management Center web interface and generates an Unable to authorize access. If you continue to have difficulty accessing this device, please contact the system administrator error.

Prior to updating, generate and install an HTTPS certificate with either a sha1WithRSAEncryption or sha256WithRSAEncryption algorithm and restart the Firepower Management Center, or use the default Firepower Management Center certificate and restart the appliance.

Similarly, if the certificate used by the Firepower Management Center was generated using a public server key larger than 2048 bits, you will not be able to log into the Management Center web interface after updating to Version 6.0.

If you are unable to log into the Management Center web interface with a public server key with more than 2048 bits, replace certificates that were created with larger public keys by generating a server certificate request (CSR) and then applying a certificate generated using that request to the Firepower Management Center. After installing the new certificate, restart the appliance.

, Version 5.4.1.

If you lose access to the web interface after updating to Version 6.0 or after uploading a certificate, contact Support.

Traffic Flow and Inspection During the Update

When you update your sensing devices, traffic either drops throughout the update or traverses the network without inspection depending on how your devices are configured and deployed: routed or transparent, inline vs passive, bypass mode settings, and so on. We strongly recommend performing the update in a maintenance window or at a time when the interruptions will have the least impact on your deployment.

Note: When you update 8000 Series clusters or stack pairs, the system performs the update one device at a time to avoid traffic interruption. When you update clustered Cisco ASA with FirePOWER Services devices, apply the update one device at a time, allowing the update to complete before updating the second device.

This section discusses traffic behavior during the following update stages:

- The update itself, including related reboots

- Configuration deployments after the update

Traffic Behavior During the Update

The following table describes how updates, including related device reboots, affect traffic flow for different deployments. Note that appliances do not perform switching, routing, NAT, and VPN during the update process, regardless of how you configure any inline sets.

Network traffic is interrupted briefly at two points :

- At the beginning of the update process, as link goes down and up (flaps) and the network card switches into hardware bypass.

- After the update finishes as link flaps and the network card switches out of bypass. Inspection resumes after the endpoints reconnect and reestablish link with the device interfaces.

The hardware bypass option is not supported on nonbypass network modules on Cisco ASA with FirePOWER Services on 8000 Series devices, or SFP transceivers on 7000 Series.

Traffic Behavior During Configuration Deployment

During the upgrade process, you deploy configurations either twice (standalone devices) or three times (devices managed by the Firepower Management Center). When you deploy, resource demands may result in a small number of packets dropping without inspection. In most cases, the deployment immediately after the upgrade restarts the Snort process. During subsequent deployments, the Snort process restarts only if, before deploying, you modify specific policy or device configurations that always restart the process when deployed.

The following table describes how different devices handle traffic during Snort process restarts.

Audit Logging During the Update

When updating appliances that have a web interface, after the system completes its pre-update tasks and the streamlined update interface page appears, login attempts to the appliance are not reflected in the audit log until the update process is complete and the appliance reboots.

Time and Disk Space Requirements for Updating to Version 6.0

The table below provides disk space and time guidelines for the Version 6.0 update. Note that when you use the Firepower Management Center to update a managed device, the Firepower Management Center requires additional disk space on its /Volume partition.

restart the update or reboot your appliance at any time during the update process. Cisco provides time estimates as a guide, but actual update times vary depending on the appliance model, deployment, and configuration. Note that the system may appear inactive during the pre-checks portion of the update and after rebooting; this is expected behavior.

The reboot portion of the update includes a database check. If errors are found during the database check, the update requires additional time to complete. System daemons that interact with the database do not run during the database check and repair.

Note: The closer your appliance’s current version to the release version (Version 6.0), the less time the update takes.

For more information, see the Firepower System Compatibility Guide.

Installing the Update

Before you begin the update, you must thoroughly read and understand these release notes, especially Supported Platforms and Compatibility and Before You Begin: Important Update and Compatibility Notes.

.

For minimum Firepower System version requirements, see Firepower Version Requirements for Updating to Version 6.0. To update your appliances, see the guidelines and procedures outlined below:

- Updating Firepower Management Centers

- Updating Managed Devices and ASA FirePOWER Modules

reboot or shut down your appliances during the update until you see the login prompt. The system may appear inactive during the pre-checks portion of the update; this is expected behavior and does not require you to reboot or shut down your appliances.
.
When to Perform the Update

Because the update process may affect traffic inspection, traffic flow, and link state, Cisco strongly recommends you perform the update in a maintenance window or at a time when the interruption will have the least impact on your deployment.

Installation Method

You must install the FireSIGHT System Version 6.0.0 Pre-Installation package prior to updating the Version 6.0. For more information, see the FireSIGHT System Release Notes Version 6.0.0 Pre-Installation Package.

Use the Firepower Management Center’s web interface to perform the update. Update the Firepower Management Center first, then use it to update the devices it manages.

Order of Installation

Update your Firepower Management Centers before updating the devices they manage.

Caution: URL category determination can introduce up to two seconds of delay in packet delivery, depending on local network conditions. If such delay is not acceptable, URL retry should not be allowed. Note that without URL retry, URL filtering may not be effective until such time as URL category and reputation determination completes for each URL. Until that time, packets that would have been filtered based on the URL’s category or reputation will be filtered based on the Uncategorized category. For more information on preventing URL retry, see Preventing URL Cache Miss Lookup Retries.
Installing the Update on Paired Firepower Management Centers

Updating Firepower Management Center in a high availability pair is not supported in Version 6.0. In order to update Firepower Management Centers in a high availability environment, you must break the pair and update each Firepower Management Center individually.In order to update to Version 6.0, you must break the high availability pair.

Installing the Update on Clustered Devices

When you install an update on clustered devices (in Version 6.0, 7000 Series or 8000 Series devices or device stacks in a high-availability pair), the system performs the update on the devices one at a time. When the update starts, the system applies the update one device at a time.

Installing the Update on Stacked Devices

When you install an update on stacked devices, the system performs the updates simultaneously. Each device resumes normal operation when the update completes. Note that:

- If the primary device completes the update before all of the secondary devices, the stack operates in a limited, mixed-version state until all devices have completed the update.

- If the primary device completes the update after all of the secondary devices, the stack resumes normal operation when the update completes on the primary device.

After the Installation

After you perform the update on either the Firepower Management Center or managed devices, you must redeploy your configurations. Deployment may cause a short pause in traffic flow and processing, and may also cause a few packets to pass uninspected. For more information, see the Firepower Management Center Configuration Guide.

There are several additional post-update steps you should take to ensure that your appliances are performing properly. These include:

- verifying that the update succeeded

- making sure that all appliances in your deployment are communicating successfully

- updating to the latest patch for Version 6.0, if available, to take advantage of the latest enhancements and security fixes

- optionally, updating your intrusion rules and vulnerability database (VDB) and redeploying your configurations

- making any required configuration changes based on the information in New Features and Functionality

The next sections include detailed instructions not only on performing the update, but also on completing any post-update steps. Make sure you complete all of the listed tasks.

Updating Firepower Management Centers

.

Use the procedure in this section to update your Firepower Management Centers, including virtual Firepower Management Centers. For the Version 6.0 update, Firepower Management Centers reboot.

Caution: Before you update the Firepower Management Center, redeploy your configurations to any managed devices. Otherwise, the managed device update may fail. reboot or shut down your appliances during the update until after you see the login prompt. The system may appear inactive during the pre-checks portion of the update; this is expected behavior and does not require you to reboot or shut down your appliances. Note: Updating a Firepower Management Center to Version 6.0 removes existing uninstallers from the appliance. in Version 6.0 and later. For more information, see the Firepower Management Center Quick Start Guide.
To update a Firepower Management Center:

Step 3 Upload the update to the Firepower Management Center by selecting System > Updates, then clicking Upload Update on the Product Updates tab. Browse to the update and click Upload.

The update is uploaded to the Firepower Management Center. The web interface shows the type of update you uploaded, its version number, and the date and time it was generated.

Step 4 Make sure that the appliances in your deployment are successfully communicating and that there are no issues reported by the health monitor.

Step 5 View the task queue (System > Monitoring > Task Status) to make sure that there are no tasks in progress.

You must wait until any long-running tasks are complete before you begin the update. After the system update completes, to reduce clutter, remove the messages for these tasks from the Message Center.

Step 6 Select System > Updates.

The Product Updates tab appears.

Step 7 Click the install icon next to the update you uploaded.

The Install Update page appears.

Step 8 Select the Firepower Management Center and click Install. Confirm that you want to install the update and reboot the Firepower Management Center.

The update process begins. You can begin monitoring the update's progress in the task queue (System > Monitoring > Task Status). However, after the Firepower Management Center completes its necessary pre-update checks, you are logged out. When you log back in, the Upgrade Status page appears. The Upgrade Status page displays a progress bar and provides details about the script currently running.

If the update fails for any reason, the page displays an error message indicating the time and date of the failure, which script was running when the update failed, and instructions on how to contact Support. Do not restart the update.
restart the update. Instead, contact Support.
When the update completes, the Firepower Management Center displays a success message and reboots.

Step 9 After the update finishes, clear your browser cache and force a reload of the browser. Otherwise, the user interface may exhibit unexpected behavior.

Step 10 Log into the Firepower Management Center.

Step 11 Review and accept the End User License Agreement (EULA). Note that you are logged out of the appliance if you do not accept the EULA.

Step 12 Select Help > About and confirm that the software version is listed correctly: Version 6.0. Also note the versions of the intrusion rule update and VDB on the Firepower Management Center; you will need this information later.

Step 13 Verify that the appliances in your deployment are successfully communicating and that there are no issues reported by the health monitor.

Step 14 If the rule update available on the Support site is newer than the rules on your Firepower Management Center, import the newer rules. Do not auto-apply the imported rules at this time.

For information on rule updates, see the Firepower Management Center Configuration Guide.

Step 15 If the VDB available on the Support site is newer than the VDB on your Firepower Management Center, install the latest VDB.

Installing a VDB update causes a short pause in traffic flow and processing, and may also cause a few packets to pass uninspected. For more information, see the Firepower Management Center Configuration Guide.

Step 16 Redeploy your configurations to all managed devices.

Deployment may cause a short pause in traffic flow and processing, and may also cause a few packets to pass uninspected. For more information, see the Firepower Management Center Configuration Guide.

Step 17 If a patch for Version 6.0 is available on the Support site, apply the latest patch as described in the for that version.
option in the Advanced Options section of the Access Control page to managed devices running Version 5.4.0.6, Version 5.4.1.5, or earlier prior to deploying configuration. For more information, see Preventing URL Cache Miss Lookup Retries.
You must update to the latest patch to take advantage of the latest enhancements and security fixes.

Preventing URL Cache Miss Lookup Retries

URL category determination can introduce up to two seconds of delay in packet delivery, depending on local network conditions. If such delay is not acceptable, URL retry should not be allowed.

When you allow URL retry, the system delays packets for URLs that have not been previously seen by the firewall while the URL category and reputation are determined so URL filtering rules can be resolved. Until the lookup of the URL category and reputation is completed, or the lookup request times out, in inline, routed, or transparent deployments the packet will be held at the firewall. If a two second time limit is reached without the category and reputation determination completing, the URL category Uncategorized is used with no reputation, and rule evaluation proceeds. Note that without URL retry, URL filtering may not be effective until such time as URL category and reputation determination completes for each URL. Until that time, packets that would have been filtered based on the URL’s category or reputation will be filtered based on the Uncategorized category.

To disable URL retry on managed devices, disable the Retry URL cache miss lookup option in the General advanced settings of the access control policy (Policies > Access Control > edit policy > Advanced >edit General Settings) and redeploy the access control policy to the device. Note that this option is enabled and URL retry is not allowed by default.

Updating Managed Devices and ASA FirePOWER Modules

After you update your Firepower Management Centers to Version 6.0, use them to update the devices they manage.

update managed devices to Version 5.4.0.6 or later prior to updating to Version 6.0.

You must use a Firepower Management Center running Version 6.0 to update any managed device that does not have its own web interface. For ASA FirePOWER modules running on the ASA 5506-X, ASA 5506H-X, ASA 5506W-X, ASA 5508-X, or ASA 5516-X, you can update the module using the Firepower Management Center or connect to the ASA device and update the ASA FirePOWER module using local management via ASDM. For more information see the Cisco ASA with FirePOWER Services Local Management Release Notes.

Updating managed devices is a two-step process. First, download the update from the Support site and upload it to the managing Firepower Management Center. Next, install the software. You can update multiple devices at once, but only if they use the same update file.

For the Version 6.0 update, all devices reboot. 7000 Series and 8000 Series devices do not perform traffic inspection, switching, routing, NAT, VPN, or related functions during the update. Depending on how your devices are configured and deployed, the update process may also affect traffic flow and link state. For more information, see Traffic Flow and Inspection During the Update.

Caution: Before you update a managed device, use its managing Firepower Management Center to redeploy your configuration to the managed device. Otherwise, the managed device update may fail. reboot or shut down your appliances during the update until after you see the login prompt. The system may appear inactive during the pre-checks portion of the update; this is expected behavior and does not require you to reboot or shut down your appliances.
To update managed devices and ASA FirePOWER modules:

Step 1 Read these release notes and complete any required pre-update tasks.

For more information, see Before You Begin: Important Update and Compatibility Notes.
install the Version 6.0 Pre-Installation Package prior to updating to Version 6.0. For more information, see Applying the Version 6.0 Pre-Installation Package.

Known Issues

You can view known issues reported in this release using the Cisco Bug Search Tool (https://tools.cisco.com/bugsearch/). A Cisco account is required.

The following known issues are reported in Version 6.0:

- If you plan on updating the Firepower Management Center from Version 5.4.0.2 or later to Version 6.0, we strongly recommend installing the FireSIGHT System Version 6.0.0 Pre-Installation package prior to updating the Version 6.0. For more information, see the FireSIGHT System Release Notes Version 6.0.0 Pre-Installation Package .

- You may experience latency if you use Firefox version 38.0.1 to view your Firepower Management Center's interface. As a workaround, use Firefox 41 or later or use a different web browser. (CSCuv11830)

- In some cases, if you create an access control policy when registering a device on a subdomain, the system creates the access control policy in the global domain instead of the subdomain when it should not. (CSCut56951)

- In some cases, if you edit the default network access policy in the advanced tab of the Access Control page ( Policies > Access Control ), the system incorrectly displays the default network access policy as an intrusion policy on the deployment dialog window. (CSCuv48221)

- Online help does not open if you click the help icon on the Select Comparison page ( ASA FirePOWER Configuration > Policies > Files > Compare Policies ) of an ASA FirePOWER module managed via ASDM. (CSCuw21863)

- In some cases, if you view All Events (Not Dropped) in the Intrusion Events table view page of a Firepower 7000 Series or 8000 Series device and sort the table by a maximum of six fields including Review By and Count and then generate a report, report generation fails. As a workaround, exclude either the Review By and Count field values or, if you include both the Review By and Count fields, only nor more than three additional field values when generating a report from the intrusion events page. (CSCuw29993)

- You cannot name a device group with a name that includes the plus ( + ) character even though the system generates a This field contains invalid characters. Only alphanumerics, hyphen ( - ), underscore ( _ ), period ( . ), and plus ( + ) are allowed message. (CSCuw44373)

- In some cases, if you edit the browser and shell timeout threshold values on the Shell Timeout page ( System > Configuration > Shell Timeout ) and redeploy, the system logs out of inactive Firepower Management Centers up to one minute after the configured threshold values. (CSCuw48568)

- In some cases, editing a file list in a domain causes any file policy in that domain to be marked out-of-date. (CSCuw52764)

- The Device Management page ( Devices > Device Management ) does not display device override values in the tooltip for device objects. (CSCuw53371)

- External certificates from Version 5.4.x are not supported in Version 6.0: the only curves supported in Version 6.0 are prime192v1 , prime256v1 , secp384r1 and secp521r1 . You must update your system to Version 6.0 to obtain supported external certificates. (CSCuw54749)

- In some cases, if you create an access control policy referencing both a file policy containing a file rule configured to Detect Files and an SSL policy configured to Decrypt--Resign or Decrypt--known key on a system sending and receiving emails with Outlook 2013, the Connection Events page ( Analysis > Connections > Events ) does not include email file attachments in generated events. (CSCuw65152)

- In some cases, if you refresh the tabs in the Device Management page ( Devices > Device Management ) or the NAT page ( Devices > NAT ) or the VPN page ( Devices > VPN ), the system does not clear the cache on the page being refreshed and the Save button is un-operational. As a workaround, cancel any edits made to the page or tab and select the device you want to edit again. (CSCuw75367)

- In some cases, if you create an SSL policy containing a certificate with more than one status, such as expired or revoked, the Certificate Status column of the Connection Events page ( Analysis > Connections > Events ) does not display a status. (CSCuw76040)

- In rare cases, if you create or edit a device interface on the Device Management page ( Devices > Devices Management ), the system generates a No cache exists to discard and resume error and you cannot deploy. As a workaround, refresh the Device Management page and redeploy. (CSCuw77505)

- In some cases, if you incorrectly configure OSPFv3, RIP or Border Gateway Protocol on a device's virtual router page ( Devices > Devices Management > Virtual Router ) and leave the configuration page without saving changes, the system generates a To revert back the configuration pop-up; click Yes to clean the virtual router configuration page of any edits or click No causes the system to generate the To revert back the configuration pop-up multiple times before saving the virtual router configuration page without any edits. (CSCuw78916)

- If you deploy a network discovery policy to a clustered or stacked Firepower 7000 Series or 8000 Series devices (in Version 6.0 known as a high availability pair), the system incorrectly counts all devices in the cluster or stack rather than indicating one device for the cluster or stack. (CSCuw79241, CSCuw79243)

- After initial setup on a Firepower Management Center, Firepower 7000 Series, or 8000 Series device, if you are connecting to the appliance from behind a network address translator (NAT) device, the system provides a redirect URL containing the IP address for the IP address you configured for the appliance rather than the NAT IP you are connecting to, and the session times out. As a workaround, correct the URL to use the NAT IP used to connect via web. (CSCuw79967)

- If you uninstall Version 5.4.1.3 or later to an earlier 5.4.x version and then update the system to Version 6.0, the update to Version 6.0 fails. Update your system to the latest version prior to updating your system to Version 6.0. (CSCuw81780)

- In some cases, if you do not select the required licenses for a device prior to device registration, the system generates an Initial policy deployment not started due to validation errors. For details, redeploy manually message. For more information on the correct licenses to select for your device, see the Licensing the FireSIGHT System chapter of the Firepower Management Center Configuration Guide . (CSCuw85743)

- In some cases, if you deploy a NAT policy containing rules targeted to Firepower 7000 Series or 8000 Series managed devices' routed interfaces and then cluster the managed devices (known is Version 6.0 as a high-availability pair), some NAT rules continue to target a managed device's routed interface instead of changing to target a high availability interface when it should. As a workaround, edit the rule containing the individual interface, manually create a high availability interface, then redeploy. (CSCuw89223)

- The HTTP Listing page ( Device > Platform Settings > Firepower Threat Defense Platform Settings > HTTP ) lists Authentication Certificate as a configurable field when it is not. (CSCuw89605)

- In some cases, the system generates events for large amounts of HTTP traffic processed by a port that is not specified in the HTTP preprocessor rule. As a workaround, add the port to the HTTP preprocessor rule with GID 119 and SID 15 . (CSCuw90033)

- If you initiate deployment while backing up the Firepower Management Center, a message does not appear to indicate that the communication channel is blocked and the policy cannot deploy. Wait until backup process is complete and then deploy. (CSCuw90629)

- In some cases, if you create an access control policy that has an intrusion policy as the default action, the variable set icon next to the default action does not display properly. As a workaround, change the default action to use a different intrusion policy, which makes the icon show up, and then change your default action back to the previous intrusion policy. (CSCuw94067)

- In some cases, the Firepower Management Center's Deploy window displays an incorrect timestamp after you update the Firepower Management Center to Version 6.0 and deploy configuration changes. (CSCuw94083)

- In some cases, if you create an OSPFv3 router but do not configure a manual router-id in the Advanced Settings tab of the router page ( Devices > Device Management > Router ), the system does not use unnamed IPv4 IP addresses and generates an OPSFv3 router process will not start as no router ID has been configured. Neither router ID in OSPFv3 nor IPv4 address configured in Interfaces error message. (CSCuw95485)

- If you create a correlation rule configured to match a MAC Vendor is condition, the system generates a Warning: no vendors match this string warning and does not execute the correlation rule. As a workaround, update your vulnerability database (VDB). If the VDB update does not resolve the issue, use the MAC Vendor contains condition instead of the MAC Vendor is condition. (CSCuw96022)

- The link to the Cisco Smart Software Manager from the Firepower Management Center Smart Licensing user interface page ( System > Local > System Policy ) directs to an updated link, which also redirects. As a workaround, if the redirect does not occur quickly enough, connect to https://software.cisco.com/#module/SmartLicensing . (CSCuw96552)

- In some cases, deploy fails on a device running Version 5.4.0 that is registered to a Firepower Management Center running Version 6.0 if you deploy an access control policy that references a file policy configured for malware protection. (CSCuw97809)

- In some cases, if you enable sensitive data detection in the Advanced Settings on the Intrusion Policy page ( Policies > Intrusion > Intrusion Policy ), then switch to another domain before saving, the system does not reload the Intrusion Policy page in the destination domain when it should. As a workaround, save or manually reload the Intrusion Policy page. (CSCuw97864)

- In some cases, if the time configured on a device running Version 6.0 is set ahead of the time configured on a Firepower Management Center, registering the managed device to the Firepower Management Center causes issues restoring connectivity. As a workaround, execute the /etc/rc.d/init.d/pm restart CLI command. If you continue to experience connectivity issues, contact Support. (CSCuw97948)

- In some cases, if the time configured on a device running Version 6.0 is set ahead of the time configured on a Firepower Management Center, registering the managed device to the Firepower Management Center causes connectivity issues and the system may not be able to restore connectivity. As a workaround, execute the /etc/rc.d/init.d/pm restart CLI command. If you continue to experience connectivity issues, contact Support. (CSCuw97948)

- In some cases, if your user interface initiates a restore, the session will be disconnected and you must log in again to see the status of restore operation. (CSCuw98296)

- In some cases, if you create two subdomains on a Firepower Management Center running Version 6.0 and register a 7000 Series or 8000 Series device, create a network object override and deploy an access control policy, then move the device from one subdomain to another subdomain, the system deletes the override value from the Object page. (CSCuw98708)

- Version 6.0 does not support the Safari web browser on systems running the MAC OS. Use Firefox, Chrome, or Internet Explorer. (CSCuw98876)

- In some cases, if the system hosting a virtual device experiences a high amount of traffic, deploying to the virtual device may cause temporary network issues. (CSCux00380)

- In some cases, intrusion events do not display the correct source IP address or the correct destination IP address. As a workaround, view the Connection Events page ( Analysis > Connections > Events ) to view the correct source and destination IP addresses of an intrusion event. (CSCux00385)

- In some cases pinholes are not created for Real-time Transport Protocol (RTP) connections established by calls using the Session Initiation Protocol (SIP), which prevents the VOIP channel creation for the SIP call. (CSCux03758, CSCux09765)

- Although an application detector is available for the Skinny (SCCP) protocol, pinholes are not created for RTP connections established by SCCP packets. (CSCux05468)

- In some cases, when deploying policies to a large number of devices, policy deployment times out and fails when Snort fails to restart. (CSCux07861)

- If you deploy a NAT policy which resides in a subdomain to a Firepower 7000 Series or 8000 Series device and move the device to new domain, deploy fails. As a workaround, create a new NAT policy in a new domain and target the correct device, then redeploy. (CSCux10651)

- In some cases, if you create a VPN deployment on a registered device and move the device from one domain to another domain, then deploy, deploy fails and the system generates a Pre-deploy Global Configuration Generation. Cannot find policy information error message. As a workaround, remove the VPN configuration prior to moving the device to another domain. An alternative workaround is to unregister and then register the device to the Firepower Management Center, then create a VPN deployment and deploy. (CSCux10820)

- Use of a certificate with an RSASSA-PSS signature algorithm on a Firepower Management Centerr is not supported in Version 6.0. If you update a Firepower Management Center using such a certificate to Version 6.0 or add such a certificate in Version 6.0, the system does not allow you to log into the Management Center web interface and generates an Unable to authorize access. If you continue to have difficulty accessing this device, please contact the system administrator error. As a workaround, prior to update, generate and install an SSL certificate with either a sha1WithRSAEncryption or sha256WithRSAEncryption algorithm and restart the Firepower Management Center, or use the default Firepower Management Center certificate and restart the appliance. If you are unable to access the user interface on your Firepower Management Center, contact Support. (CSCux30610)

- In some cases, if you create an access control policy referencing an SSL policy that contains a network object with multiple entries on a managed Firepower appliance running Version 5.4 or later and you update the system to Version 6.0, deploying the policy fails on a Firepower Management Center running Version 6.0. As a workaround, edit the SSL policy after updating the system to Version 6.0 and remove the network object, then add the network object and redeploy. (CSCux31618)

- If the certificate used by your Firepower Management Center was generated using a public server key larger than 2048 bits, you will not be able to log into the Firepower Management Center web interface after updating to Version 6.0. As a workaround, replace certificates that were created with larger public keys by generating a server certificate request and then applying a certificate generated using that request to the Firepower Management Center. You can do the server certificate request and the certificate upload through the local configuration settings on the Firepower Management Center ( System > Local > Configuration > HTTPS Certificate ). If you generate a certificate without using a CSR from the Firepower Management Center, use a public key of 2048 bits or less. If you generate a certificate that contains more than 2048 bits and lose access to the Management Center web interface, contact Support. (CSCux35430)

- In some cases, if you deployed an access control policy that contains a custom URL, the CPU experienced high usage and the system experienced issues. (CSCux35554)

- If a device running Firepower Threat Defense is registered to a Firepower Management Center running Version 6.0 ten days or more, the system experiences the following issues: registering a new device the Firepower Management Center generates a CSM failed state: (2) CSM can not provide device state (2) error and device registration fails; updating the Firepower Management Center from 6.0.0 to a later version generates an Installation failed. Peer discovery incomplete. Please retry after few moments error and the update fails; backing up the Firepower Management Center generates a Registration or CSM state are blocking backup error and backup fails; attempting to create, update, or delete a domain on the Firepower Management Center generates an A sensor registration process is running. Please wait until process completes. error and the system does not successfully create, update, or delete the selected domain. As a workaround, download the install file for Version 6.0 through the Firepower Management Center and execute the /usr/local/sf/bin/install_update.pl /var/sf/updates/[UPGRADE_PKG_NAME].sh CLI command as the root user to update the Firepower Management Center to Version 6.0 instead of updating through the web interface. (CSCux89875)

- Environments with multiple user accounts with same email address scrambles/crashes SFDataCorrelator. (CSCvf56267)

- 256 low block count leads to traffic failures due to alloc to inspect snort. (CSCvg45236)
