How does encryption contribute to system hardening? ()

Question

Options

• ABy managing user permissions and access controls
• BBy reducing the attack surface of the system
• CBy implementing strong password policies
• DBy protecting data at rest and in transit from unauthorized access

• B
  4% (1)
• D
  96% (23)

Explanation

Encryption converts data into an unreadable ciphertext, protecting it from unauthorized access whether it is stored on a disk (data at rest) or being transmitted across a network (data in transit). This directly hardens a system by ensuring that even if data is intercepted or stolen, it remains unreadable without the decryption key. Option A describes access control (IAM). Option B describes attack surface reduction (e.g., disabling unused services). Option C describes password policies - all valid hardening techniques, but not what encryption specifically does.
