Kerberos Domain Trust Discovery via TGT Request
This rule detects Kerberos Domain Trust Discovery attempts by monitoring for a high volume of Kerberos Ticket Granting Ticket (TGT) requests to port 88 (Kerberos) on the home network. A threshold of 20 requests from a single source IP within 10 seconds triggers the alert, indicating a potential network scan activity aimed at mapping domain trusts.
