CompTIA Security+ (SY0-701) — Question 447

A security administrator is implementing encryption on all hard drives in an organization. Which of the following security concepts is the administrator applying?

Answer options

• A. Integrity
• B. Authentication
• C. Zero Trust
• D. Confidentiality

Correct answer: D

Explanation

The correct answer is D, Confidentiality, as encryption is primarily used to protect data from unauthorized access, ensuring that only those with the proper decryption key can access the information. Options A (Integrity) and B (Authentication) are not directly related to encryption, while C (Zero Trust) refers to a security model rather than a specific technique like encryption.
