Kerberos Overview
We validate this area during scoped assessments, documenting impact and remediation guidance.
Why it matters
- Kerberos: A network authentication protocol using symmetric key cryptography to authenticate users and services in a distributed environment. - Client: The entity requesting authentication. - KDC (Key Distribution Center): Issues tickets for authentication, consisting of: - AS (Authentication Service): Issues the Ticket Granting Ticket (TGT). - TGS (Ticket Granting Service): Issues service tickets for accessing resources. - Service: The resource or application the client is trying to access.
