Which of the following most securely protects data at rest?

The correct answer is B. AES-256. AES with a 256-bit key is strong, standards-approved symmetric encryption specifically suited for protecting stored data. It renders the ciphertext unreadable without the key, meets common regulatory requirements (e.g., FIPS 140-2 validated implementations), and provides far stro

Explanation

AES with a 256-bit key is strong, standards-approved symmetric encryption specifically suited for protecting stored data. It renders the ciphertext unreadable without the key, meets common regulatory requirements (e.g., FIPS 140-2 validated implementations), and provides far stronger assurance for data at rest than transport protocols, masking, or password salting techniques that don’t actually encrypt the full dataset.
