Identity Terminology

This topic discusses common terminology for user identity and user control.

User awareness

Identifying users on your network using identity sources (such as or TS Agent). User awareness enables you to identify users from both authoritative (such as Active Directory) and non-authoritative (application-based) sources. To use Active Directory as an identity source, you must configure a realm and directory. For more information, see About User Identity Sources.

User control

Configuring an identity policy that you associate with an access control policy. (The identity policy is then referred to as an access control subpolicy.) The identity policy specifies the identity source and, optionally, users and groups belonging to that source.

By associating the identity policy with an access control policy, you determine whether to monitor, trust, block, or allow users or user activity in traffic on your network. For more information, see Access Control Policies.

Authoritative identity sources

A trusted server validated the user login (for example, Active Directory). You can use the data obtained from authoritative logins to perform user awareness and user control. Authoritative user logins are obtained from passive and active authentications:

• Passive authentications occur when a user authenticates through an external repository. ISE/ISE-PIC, the TS Agent, Microsoft Active Directory, and Microsoft Azure Active Directory are passive authentication user repositories supported by the system.

  Passive authentications occur when a user authenticates with Cisco ISE.

• Active authentications occur when a user authenticates through preconfigured managed devices. Captive portal is another name for active authentication. Active authentication generally uses the same user repositories as passive authentication (the exceptions being ISE/ISE-PIC, and TS Agent, which are passive only).

Non-authoritative identity sources

An unknown or untrusted server validated the user login. Traffic-based detection is the only non-authoritative identity source supported by the system. You can use the data obtained from non-authoritative logins to perform user awareness.
