Kerberos Threat Detection

Description

This bundle finds weak encryption algorithms in Kerberos connections, tracks usage of Kerberos services, and detects forged ticket-granting tickets (TGTs) that might allow attackers to escalate privileges or access Kerberos services.

Kerberos Threat Detection Dashboard

Note: The bundle might report false positives for forged tickets while the bundle initially caches tickets. By default, the trigger caches tickets for 24 hours, but this value can be changed to match your Kerberos ticket renewal time policy by modifying the renewal_time variable in the Kerberos Threat Detection trigger.
