Dynamic Attributes Connector

The following topics discuss how to configure and use the Dynamic Attributes Connector.

About the dynamic attributes connector

The dynamic attributes connector enables your access control 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 Cisco Secure Dynamic Attributes Connector queries cloud services such as VMware vCenter and provides information such as VLANs, networks, and tags to the secure management center to use as selection criteria in access control rules. This way, you don't have to constantly update network objects when IP address information (for example) in your cloud systems change"

  • 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.

Enable the dynamic attributes connector

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 control rules.

Procedure

Step 1

Log in to the Secure Firewall Management Center if you have not done so already.

Step 2

Click Integration > 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.

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.

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 Tag.

  • (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.

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 man-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.
