Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Rotating logs daily
Why it's wrong here
Rotation helps manage size but does not prevent tampering.
- ✗
Encrypting logs with a symmetric key
Why it's wrong here
Encryption protects confidentiality, not integrity against tampering.
- ✗
Storing logs on the local system drive
Why it's wrong here
Local storage is vulnerable to tampering if the system is compromised.
