User-ID

Palo Alto Networks feature that maps IP addresses to usernames so firewall policies can be based on users and groups.

Definition

User-ID collects mappings from sources such as domain controller logs, GlobalProtect, captive portal, syslog, and Cloud Identity Engine. Policies can then reference users and groups instead of IPs. It supports visibility and least-privilege access by identity.

Example

Only members of the Engineering group can reach the build servers, regardless of which IP they receive.

Exam tip

User-ID enables identity-based policy; mappings must be accurate and timely.
