SSCP Access Controls Practice Question
A security analyst is investigating an account compromise. The organization uses Kerberos for single sign-on. Which TWO of the following would help in tracking the source of the compromise?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Authentication service (AS) logs with timestamps and IP addresses
Kerberos logs ticket requests and TGT usage, which can trace authentication events. TGT expiration and session key details are part of the protocol but less directly useful for source identification.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Password hash history
Why it's wrong here
Password hash history is not part of Kerberos logs; it's stored in the directory.
- ✗
Ticket-Granting Ticket (TGT) expiration time
Why it's wrong here
TGT expiration time doesn't indicate the source of compromise; it's just a validity period.
- ✓
Authentication service (AS) logs with timestamps and IP addresses
Why this is correct
AS logs show initial authentication attempts with source IPs.
- ✓
Logs from the Key Distribution Center (KDC) showing TGT requests
Why this is correct
KDC logs record which users requested TGTs and from which workstations.
- ✗
Service ticket session keys
Why it's wrong here
Session keys are encrypted and not typically logged; they don't aid in source identification.
