Entra ID Introduces Linkable Token Identifiers for Audit Events

Linkable token identifiers is a new Entra ID feature that adds a GUID to all the audit events for a session. The new identifiers make it easier to track all user actions taken during a session, and should be of great advantage to security investigators who need to know if an account is performing suspicious actions, possibly due to an attacker compromise.
