Free Isaca Cybersecurity Audit Certificate Actual Exam Questions - Question 11 Discussion

Option C, encryption secures data even if the device is physically compromised.

Maybe A is better since password-based access control can stop unauthorized users from even logging in, which seems like the first line of defense if the computer’s stolen. Encryption helps but only if the data’s encrypted properly and keys aren’t stored locally.

C imo, secret key encryption is the best here since it actually protects the data itself, not just access or verification. Passwords and digital signatures won’t stop someone who has the physical computer.
