Explanation
Encrypting hard drives protects data from being read by unauthorized parties, which is the definition of confidentiality - ensuring information is accessible only to those permitted to see it. Hard drive encryption specifically addresses the scenario where a device is lost or stolen, keeping the data unreadable without the correct key.
Why the distractors are wrong:
- A. Integrity - concerns ensuring data hasn't been altered or tampered with, not protecting it from unauthorized viewing.
- B. Authentication - is about verifying who someone is (passwords, biometrics, tokens), not protecting data at rest.
- C. Zero Trust - is a network security model ("never trust, always verify") focused on access control architecture, not encryption of stored data.
Memory tip: Think of the CIA triad - Confidentiality, Integrity, Availability. Encryption = Confidentiality because it keeps data secret ("confidential"). Whenever you see encryption protecting data from being seen, map it to Confidentiality.
