About the dynamic attributes connector

The dynamic attributes connector enables your access control and DNS policy to adapt in real time to the changes in public and private cloud workloads and business-critical software-as-a-service (SaaS) applications. It simplifies policy management by keeping rules up to date without tedious manual updates and policy deployment. Customers require policy rules to be defined based on non-network constructs such as VM name or security group, so that firewall policy is persistent even when the IP address or VLAN changes.

How it works

This topic discusses the architecture of the dynamic attributes connector.

The following figure shows how the system functions at a high level.

The system supports certain public cloud providers.

This topic discusses supported connectors (which are the connections to those providers).
The dynamic attributes connector is provided with Secure Firewall Management Center.

Network download mode

The dynamic attributes connector always operated in network download mode. In this mode, the images required to make it work are downloaded from the internet. If your security requirements are strict, you can use air gapped mode.

Architectural overview:

System requirements for the Dynamic Attributes Connector

The Dynamic Attributes Connector has the following memory requirements:


FMCv: Amount of RAM	Secure Firewall Management Center hardware model	Maximum number of (connectors + Azure AD realms)
At least 32 GB	Firepower 1000, Firepower 1600, vFMC	10
At least 64 GB	Firepower 2500, Firepower 2600,vFMC 300	20
At least 128 GB	Firepower 4500, Firepower 4600	30

The preceding limits apply to both virtual machines and physical machines.

The system prevents you from exceeding these limits to avoid deployment issues.

Enable the dynamic attributes connector

Enable the dynamic attributes connector to allow objects from cloud networking products to be used in Secure Firewall Management Center access controland DNS rules.

This task discusses how to enable the dynamic attributes connector in the Secure Firewall Management Center. The dynamic attributes connector is an integration that enables objects from cloud networking products to be used in Secure Firewall Management Center access controland DNS rules.

Procedure

Step 1	Log in to the Secure Firewall Management Center if you have not done so already.
Step 2	Click Integrations > Dynamic Attributes Connector.
Step 3	Slide to Enabled.
Step 4	Messages are displayed while the dynamic attributes connector is enabled. In the event of errors, try again. If errors persist, contact Cisco TAC.

What to do next

See Create a connector.

Configure networks and subnets for Docker containers

The Dynamic Attributes Connector uses Docker containers to retrieve connector data in the Secure Firewall Management Center. To avoid conflicts with the Secure Firewall Management Center management interface and other IP addresses used in your network, you can optionally use the command discussed in this section to change Docker IP addresses and ranges.

About Docker networks

The Docker daemon is used by the dynamic attributes connector requires the following networks:

docker0 which is used internally by the Docker daemon.
A series of IPv6 networks named vethnumber.

These are internal bridge networks used by the dynamic attributes connector.
Docker bridge networks used by dynamic attributes connector connectors named br-number.

Before you enable the dynamic attributes connector, there is only one Docker interface, named docker0, set to 172.18.0.1/16 (for a Secure Firewall Management Center Virtual; on-premises managers use different IP address ranges). The table in the Examples section provides details.

Change Docker networks and subnets

First enable the dynamic attributes connector as discussed in Enable the dynamic attributes connector.

To change Docker networks and subnets, run /usr/local/sf/bin/change_docker_subnet.sh -b CIDR-network -s address-pool-size as a user with root privileges where:

-b CIDR-network sets a network base address pool in CIDR notation.
-s address-pool-size sets a netmask for the network base address. You can use this option to limit the number of addresses in a base address range in the event the network range overlaps existing network ranges; in particular, we recommend certain -s values for Secure Firewall Management Center models to make sure you don't exceed the available RAM in the machine. (Docker containers are used by dynamic attributes connector connectors and those limits are shown in System requirements for the Dynamic Attributes Connector.)

Important

The networks you assign to Docker must be in an internal network range and must not conflict with networks used by the Secure Firewall Management Center or by other devices in your internal network.

Examples

The following table shows examples.


Secure Firewall Management Center model	Recommended -s value	Sample -b value	Dynamic Attributes Connector container addresses used
Firepower 1000, Firepower 1600, vFMC	27 (netmask 255.255.255.224)	172.19.0.0/16	30 IP addresses `docker0`: 172.19.0.1 Bridge networks `br-number` gateway `172.19.0.33` with subnet `172.19.0.32/27` Connectors created in networks like `172.19.0.38/27`, `172.19.0.39/27`, and so on
Firepower 2500, Firepower 2600, vFMC 300	26 (netmask 255.255.255.192)	192.168.0.0/16	62 IP addresses `docker0`: 192.168.1.1 Bridge networks `br-number` gateway `192.168.1.65`with subnet `192.168.1.64/26` Connectors created in networks like `192.168.1.71/26`, `192.168.1.72/26`, and so on
Firepower 4500, Firepower 4600	25 (netmask 255.255.255.128)	192.168.0.0/16	126 IP addresses `docker0`: 192.168.1.1 Bridge networks `br-number` gateway `192.168.1.129`with subnet `192.168.1.128/25` Connectors created in networks like `192.168.1.136/25`, `192.168.1.135/25`, and so on

For reference, the complete commands follow:

sudo /usr/local/sf/bin/change_docker_subnet.sh -b 172.19.0.0/16 -s 27

sudo /usr/local/sf/bin/change_docker_subnet.sh -b 192.168.0.0/16 -s 26

sudo /usr/local/sf/bin/change_docker_subnet.sh -b 192.168.0.0/16 -s 25

Verify the networks

To verify your network settings, enter sudo docker network inspect muster-net. The command results are displayed in JSON format.

Troubleshoot

Following are some solutions to common errors you might encounter using this command.

Error: Pull subnet value can not be greater than size

Solution: Change the value of -s so it is less than the CIDR network value.

For example,

INCORRECT: sudo /usr/local/sf/bin/change_docker_subnet.sh -b 172.19.0.0/16 -s 8

CORRECT: sudo /usr/local/sf/bin/change_docker_subnet.sh -b 172.19.0.0/16 -s 20

Error: After running the command, the Docker networks are wrong.

Solution: Restart the Docker daemon: sudo pmtool restartbyid docker

Error: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Solution: Restart Docker: pmtool restartbyid docker

Error: Input can't be empty

The -s parameter is required.

Error: Pull size - 32 - can not be greater than 32 or less than 0

Solution: Change the value of -s so it is greater than 0 and less than 32.

About dynamic objects in access control rules or DNS rules

A dynamic object is automatically pushed from the dynamic attributes connector to the Secure Firewall Manager after you create connectors and save a dynamic attributes filter on the connector.

You can use these dynamic objects on the access control rule's or DNS rule's Dynamic Attributes tab page. You can add dynamic objects as source or destination attributes; for example, in an access control block rule, you can add a Finance dynamic object as a destination attribute to block access to Finance servers by whatever objects match the other criteria in the rule.

Note

You cannot create dynamic attributes filters for Generic Text, Office 365, Azure Service Tags, Webex, or Zoom. These types of cloud objects provide their own IP addresses.

Create dynamic attributes filters

Create dynamic attributes filters to expose them as dynamic objects in Secure Firewall Management Center for use in access control policies.

Dynamic attributes filters that you define using the Dynamic Attributes Connector are exposed in the Secure Firewall Management Center as dynamic objects that can be used in access control policies. For example, restrict access to an AWS server for the Finance Department to only members of the Finance group defined in Microsoft Active Directory.

Note

You cannot create dynamic attributes filters for Generic Text, Office 365, Azure Service Tags, Webex, or Zoom. These types of cloud objects provide their own IP addresses.

For more information about access control or DNS rules, see Create access control rules or DNS rules using dynamic attributes filters.

Before you begin

Create a connector

Procedure

Step 1

Log in to the Secure Firewall Management Center.

Click Integrations > Dynamic Attributes Connector > Dynamic Attributes Filters.

Step 2

Do any of the following:

Add a new filter: click Add ().

Name	Unique name to identify the dynamic filter (as a dynamic object) in a policy and in the Secure Firewall Management Center Object Manager (External Attributes > Dynamic Object).
Connector	From the list, click the name of a connector to use.
Query	Click Add .

Step 4

To add or edit a query, enter the following information.


Item	Description
Key	Click a key from the list. Keys are fetched from the connector.
Operation	Click one of the following: Equals to exactly match the key to the value. Contains to match the key to the value if any part of the value matches.
Values	Click either Any or All and click one or more values from the list. Click Add another value to add values to your query.

Step 5

Click Show Preview to display a list of networks or IP addresses returned by your query.

Step 6

When you're finished, click Save.

Step 7

(Optional.) Verify the dynamic object in the Secure Firewall Management Center.

Log in to the Secure Firewall Management Center as a user with the Network Admin role at minimum.
Click Objects > External Attributes > Dynamic Object.

The dynamic attribute query you created should be displayed as a dynamic object.

Dynamic attributes rule conditions

Dynamic attributes include:

(Source or destination.) Dynamic objects (such as from the dynamic attributes connector)

The dynamic attributes connector enables you to collect data (such as networks and IP addresses) from cloud providers and send it to the Secure Firewall Management Center so they can be used in access control rules.

For more information about the dynamic attributes connector, see About the dynamic attributes connector.
(Source only.) SGT objects contain tags either manually defined or defined in ISE. For more information, see Source and destination security group tag (SGT) matching and Security group tags.
(Source only.) Location IP objects, defined by Cisco ISE
(Source only.) Device type objects, defined by Cisco ISE (also referred to as endpoint profile objects)

Dynamic attributes can be used as source criteria and destination criteria in access control rules. Use the following guidelines:

Objects of different types are ANDd together
Objects of a similar type are ORd together

For example, if you choose source destination criteria SGT 1, SGT 2, and device type 1; the rule is matched if device type 1 is detected on either SGT 1 or SGT 2. As another example, if you select both a security group tag, and a dynamic object that lists IP addresses, the rule matches if traffic with the tag originates from (or is destined to) one of those IP addresses.

View dynamic objects in the Secure Firewall Management Center

(Optional.) The following task discusses how you can view Cisco APIC network objects in the Objects > External Attributes > Dynamic Object.

Before you begin

Complete all of the previous tasks related to integrating Cisco APIC with the Secure Firewall Management Center.

Procedure

Step 1

Dynamic firewall

These topics describe how to integrate user identity data (including Microsoft AD and ISE) with user trust data provided by Identity Intelligence to enhance your ability to detect identity-based exploits in your network.

About the dynamic firewall

Previously, the Secure Firewall Management Center collected information about users exclusively from the configured identity source, such as Microsoft Active Directory, the passive identity agent, Cisco Identity Services Engine (Cisco ISE), and so on. This information generally included user name, group, and IP address.

The dynamic firewall enables you to add user risk scores from Cisco Identity Intelligence to identity source-provided information so you can set policies based on always-current user posture and risk. We enable you to pair user identity with intelligence and use that information in reporting and access control policies.

To use the dynamic firewall, you must:

Have an Identity Intelligence tenant

See Duo Identity Security with Cisco Identity Intelligence.
Enable the Dynamic Attributes Connector
Set up an identity source:
- Cisco Identity Services Engine (Cisco ISE)
- pxGrid Cloud
  
  pxGrid Cloud combines identity and posture in the same feed
  
  More information: What is pxGrid?
In addition to providing authentication information, Cisco ISE and pxGrid Cloud can provide the following:
- SGT Exchange Protocol over TCP (SXP) binding and directory session information if desired. For more information, see the Cisco Identity Services Engine Administrator Guide
- Posture and mobile device management compliance. For more information, see Compliance.
Set up an identity realm:
- Create an LDAP realm or an Active Directory realm and realm directory
- Create a Microsoft Azure AD (SAML) realm for passive authentication

The identity source provides authentication information (login, logout) as well as posture. The identity source can also provide SXP binding and session directory information if desired.

The identity realm provides user, group, and IP address information.

How to configure the dynamic firewall

This topic helps you understand the concepts and options to configure the dynamic firewall discussed in About the dynamic firewall.

Summary

The dynamic firewall integrates an identity source (such as Cisco ISE) with Cisco Identity Intelligence, which provides user trust information to the Secure Firewall Management Center.

Configure Cisco Identity Intelligence to collect user trust information.
Configure a supported Secure Firewall Management Center identity source.
Configure a supported identity realm.
Enable the dynamic attributes connector.
Configure the dynamic firewall.

Workflow

The following procedure provides a high-level overview of how to configure the dynamic firewall.

As a Duo user with the Owner role, provision a Cisco Identity Intelligence tenant. You can provision a tenant from Duo Advantage as discussed in Provision Your Cisco Identity Intelligence Tenant.
In Cisco Identity Intelligence, create an API integration and use the information to set up the dynamic firewall. We use Cisco Identity Intelligence to find user and device risk information in your network. For more information about Cisco Identity Intelligence, see How-to Guides. For more information about this task, see Get required information for Identity Intelligence.
(Microsoft Azure AD realm only.) In Identity Intelligence, create a Microsoft Entra ID integration. For more information, see Microsoft Entra ID (Azure AD) Data Integration.
Create an identity source. (If you already have an identity source, continue with the next step.) You can do this in any of the following ways:
- The Configure Dynamic Firewall dialog box displays Configure links to start setting up your identity source.
- Click Integrations > Identity > Identity Sources.
For more information about creating identity sources, see:
Create an identity realm. We support the following realms:
- Create an LDAP realm or an Active Directory realm and realm directory Only Microsoft AD is supported; LDAP realms are not supported.
- Create a Microsoft Azure AD (SAML) realm for passive authentication
Enable the dynamic attributes connector. The dynamic attributes connector is required to use the dynamic firewall. It enables your identity source to integrate with Identity Intelligence to provide enhanced insights into user activity. See Enable the dynamic attributes connector.
Create the dynamic firewall instance. (If you already have a dynamic firewall instance, continue with the next step.) Click Integrations > Dynamic Attributes Connector and click Configure Dynamic Firewall. See Create a dynamic firewall instance.
Associate your identity source with Cisco Identity Intelligence. See Associate an identity source with Identity Intelligence.
View system-defined filters. We create dynamic attributes filters for the following:
- Untrusted device
- Trusted device
- Untrusted user
- Questionable user
You can edit or replace these dynamic attributes filters as discussed in Create dynamic attributes filters.
View system-defined access control rules. We create an access control policy named Dynamic Firewall Policy (or similar) with the following rules:
- Block an untrusted user from any source network to any destination network.
- Monitor a questionable user from any source network to any destination network.
- Block an untrusted device from any source network to any destination network.
You can edit or delete the access control policy and rules as discussed in View and edit the system-created access control policy.

Security requirements

To safeguard the dynamic attributes connector, you should install it on a protected internal network. Although the dynamic attributes connector is configured to have only the necessary services and ports available, you must make sure that attacks cannot reach it.

If the dynamic attributes connector and the Secure Firewall Management Center reside on the same network, you can connect the Secure Firewall Management Center to the same protected internal network as the dynamic attributes connector.

Regardless of how you deploy your appliances, inter-system communication is encrypted. However, you must still take steps to ensure that communications between appliances cannot be interrupted, blocked, or tampered with; for example, with a distributed denial of service (DDoS) or adversary-in-the-middle attack.

Internet access requirements

By default, the dynamic attributes connector is configured to communicate with the Firepower System over the internet using HTTPS on port 443/tcp (HTTPS). If you do not want the dynamic attributes connector to have direct access to the internet, you can configure a proxy server.

The following information informs you of the URLs the dynamic attributes connector use to communicate with the Secure Firewall Management Center and with external servers.

Table 5. Dynamic Attributes Connector access requirements
