An organization wants to ensure that system logs are tamper-proof after generation. Which control should be implemented?
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
✓
Use a write-once read-many (WORM) storage device.
WORM storage prevents modification or deletion of logs, ensuring tamper-proofing after generation. Option A (compressing logs) does not prevent tampering. Option C (local hard drive) is not tamper-proof. Option D (encryption in transit) protects during transmission but not at rest on the storage device.

- ✗
Compress logs before archiving.
Why it's wrong here
Compression does not provide integrity protection.

Use a write-once read-many (WORM) storage device.
Why this is correct
WORM devices ensure data cannot be overwritten or deleted.
- ✗
Store logs on the local hard drive of each server.
Why it's wrong here
Local storage can be altered if the server is compromised.
