User Control with the Passive Identity Agent

The following topics discuss how to configure and use the passive identity agent.

The Passive Identity Agent Identity Source

The passive identity agent identity source sends session data from Microsoft Active Directory (AD) to the Cisco Security Cloud Control. All you need is a supported Microsoft AD setup as discussed in About Realms and Realm Sequences.


Note

You do not need to configure the Cisco Identity Services Engine (ISE) to use this identity source.

Passive identity agent roles

The passive identity agent supports the following roles:

  • Standalone: A passive identity agent that is not part of a redundant pair. A standalone agent can download users and groups from multiple Active Directory servers and domain controllers, provided the software is installed on all of them.

  • Primary: (Primary agent in a redundant pair.) Can be installed on a Microsoft AD domain controller, directory server, or any network client.

    Handles all communication with the Cloud-delivered Firewall Management Center unless it stops communicating, in which case communication is handled by secondary agents.

  • Secondary: (Secondary, or backup, agent in a redundant pair.) Can be installed on a Microsoft AD domain controller, directory server, or any network client.

    Monitors the health of the primary agent and takes over if the primary agent stops communicating with the Cloud-delivered Firewall Management Center.

Passive identity agent system requirements

The passive identity agent requires the following:

  • If you install it on a Windows Active Directory server, the server must run Windows Server 2008 or later.

  • If you install it on a Windows client attached to the domain, the client must run Windows 8 or later.

  • The system clock on all systems must be synchronized. We strongly recommend using the same NTP servers on all of them. This means:

    • The Security Cloud Control.

      For more information, see Configure NTP Server.

    • All Windows Active Directory servers and domain controllers.

    • The machine on which the passive identity agent is installed.

  • Security Cloud Control must run November 8, 2024 or later.

  • You must enable Snort 3 on the Secure Firewall Threat Defense devices.

Passive identity agent limitations

The passive identity agent the following limitations:

  • Up to 10 agents simultaneously

  • One passive identity agent identity source can monitor up to 50 AD directories

  • Up to 300,000 concurrent user sessions

  • IPv6 addresses are not supported

Deploy the passive identity agent

For information about deployment options, see Deploy the Passive Identity Agent.

Deploy the Passive Identity Agent

You can install the Passive Identity Agent software on any machine that is part of a Microsoft Active Directory (AD) domain you want to use for user awareness and control. In other words, you can install it on any of the following:

  • The Microsoft Active Directory server

  • A domain controller

  • A client connected to the network that is neither the directory server nor a domain controller

Any particular passive identity agent can monitor one or several Active Directory domain controllers in the same domain.

The machine on which the passive identity agent must communicate with the Cloud-delivered Firewall Management Center using the TLS/SSL protocol. For more information, see Internet Access Requirements for the Passive Identity Agent.

Types of agents

You can configure the following types of agents on the Microsoft AD directory server, domain controller, or on any client connected to the domain:

  • Standalone agent: One agent that can monitor one or several Active Directory domain controllers in the same domain.

  • Primary agent and secondary agent that can monitor one or several AD domain controllers in the same domain: To provide redundancy, you can install a primary and secondary agent on different machines. The primary is responsible for communicating with the Cloud-delivered Firewall Management Center but if communication fails, the secondary agent takes over.

See one of the following topics for more information.

Simple Passive Identity Agent Deployment

The following diagram shows the simplest passive identity agent deployment.

The simplest Passive Identity Agent is one standalone agent installed on the Active Directory domain controller. This agent sends user name and IP info to the firewall manager

In the preceding example, a standalone passive identity agent is installed on the AD domain controller. Users log in and out of the AD domain and the agent sends user name and IP address information to the Cloud-delivered Firewall Management Center. As users access the network, access control and identity policies deployed to the Secure Firewall Threat Defense determine whether or not, and how, access is allowed.

You can install a passive identity agent on the AD domain controller, directory server, or on any client connected to the domain you wish to monitor.

Single Passive Identity Agent Monitoring Multiple Domain Controllers

The following diagram shows a standalone passive identity agent that monitors several AD domain controllers.

One standalone passive identity agent can be installed on the Active Directory domain and send user IP address information to the firewall manager

In the preceding diagram, the standalone passive identity agent is installed on a client attached to the AD domain (or on the domain controller itself). Users log in to any domain controller and the agent sends user and IP address information to the Cloud-delivered Firewall Management Center. As users access the network, access control and identity policies deployed to the Secure Firewall Threat Defense determine whether or not, and how, access is allowed.

You can install a passive identity agent on the AD domain controller, directory server, or on any client connected to the domain you wish to monitor.

Multiple Passive Identity Agents Monitoring Multiple Domain Controllers

The following figure shows standalone monitoring multiple AD domain controllers:

  • In AD domain 1, a standalone passive identity agent installed on a machine attached to AD domain controller 1 sends user and IP address mapping data to the Cloud-delivered Firewall Management Center.

  • In AD domain 2, standalone agents installed on AD domain controllers 1 and 2 send user and IP address mapping data to the Cloud-delivered Firewall Management Center.

You can deploy several standalone passive identity agents to monitor multiple Active Directory networks and send user IP information to the firewall manager

You can install a passive identity agent on the AD domain controller, directory server, or on any client connected to the domain you wish to monitor.

The preceding figure shows three passive identity agents, each configured as a standalone. To do this:

  1. Create two Microsoft AD realms: one for each AD domain.

    See Create an LDAP Realm or an Active Directory Realm and Realm Directory.

  2. For AD domain 2, create two directories, one for each domain controller.

  3. Install the Passive Identity Agent software on a client that can log in to the domain.

    Configure each passive identity agent individually to communicate with the Cloud-delivered Firewall Management Center on which you configure the passive identity agent source.

    See Install the Passive Identity Agent Software.

  4. Create the passive identity agent identity source.

    See Create a Primary or Secondary Passive Identity Agent Identity Source.

Passive Identity Agent Primary/Secondary Agent Deployments

To provide redundancy and to avoid a single point of failure, you can configure primary and secondary passive identity agents in any of the ways shown in this topic.

You can install a passive identity agent on the AD domain controller, directory server, or on any client connected to the domain you wish to monitor.

Single AD domain controller with primary and secondary agents

The following figure shows how to set up primary and secondary passive identity agents on one AD domain controller. If the primary agent fails, the secondary takes over.

The advantage of using primary and secondary passive identity agents is that if the primary agent does not communicate with the Cloud-delivered Firewall Management Center for any reason, the secondary takes over. You can use any of the other types of deployments (in other words, primary/secondary agents monitoring one AD domain or multiple domains

To set this up:

  1. Create a Microsoft AD realm that has one directory for the domain controller.

    See Create an LDAP Realm or an Active Directory Realm and Realm Directory.

  2. Install the passive identity agent software on any two network machines connected to the domain controller.

    Configure each passive identity agent individually to communicate with the Cloud-delivered Firewall Management Center on which you configure the passive identity agent source.

    See Install the Passive Identity Agent Software.

  3. Create the identity source.

    See Create a Primary or Secondary Passive Identity Agent Identity Source.

Multiple AD domain controllers, primary and secondary agents

An example of primary and secondary agents installed on different AD domain controllers, all sending user IP information to the firewall manager

The preceding figure shows how to configure primary and secondary agents to monitor three AD domain controllers. If the primary agent fails, the secondary agent takes over.

To set this up:

  1. Create a Microsoft AD realm that has one directory for the domain controller.

    See Create an LDAP Realm or an Active Directory Realm and Realm Directory.

  2. Install the passive identity agent software on any machine connected to the domain controller.

    Configure each passive identity agent individually to communicate with the Cloud-delivered Firewall Management Center on which you configure the passive identity agent source.

    See Install the Passive Identity Agent Software.

  3. Create the identity source.

    See Create a Primary or Secondary Passive Identity Agent Identity Source.

Security Requirements for the Passive Identity Agent

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

If the passive identity agent and the Security Cloud Control reside on the same network, you can connect the Security Cloud Control to the same protected internal network as the passive identity agent.

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 for the Passive Identity Agent

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

If your Cloud-delivered Firewall Management Center cannot communicate with the machine on which the passive identity agent is installed, you must use a proxy with the HTTPS protocol enabled.

The way you do this is up to you; for example, you might have a commercial proxy and use a Windows system proxy with HTTPS enabled to communicate with it.

The following information informs you of the ports the passive identity agent use to communicate with each other, with the Security Cloud Control, and with Microsoft Active Directory.

Table 1. Passive Identity Agent port requirements
