Assertion (A): Audit logs should be written to a destination the audited account cannot modify.
Reason (R): An attacker with control of the account would otherwise delete the record of their activity.

  • A.Both A and R are true, but R is not the correct explanation of A
  • B.A is true but R is false
  • C.A is false but R is true
  • D.Both A and R are true, and R is the correct explanation of A

Answer: D

Correct answer: Both A and R are true, and R is the correct explanation of A

Both are true and the reason gives the threat. If the audited account can write to its own log destination, an attacker who takes it over can erase the record of the takeover, and the log is worth nothing at the moment it matters most. Writing to a separate account with append-only permissions and object locking preserves the evidence, which is why it is a standard requirement rather than a refinement.
