Which term describes the set that contains Confidentiality, Integrity, and Availability?

• A. CIA Triad
• B. Threat Actor
• C. Attack Vector
• D. Modular Arithmetic

Answer: (A)

Understanding security goals starts with the three core aims: confidentiality, integrity, and availability. Confidentiality keeps information from being disclosed to unauthorized people. Integrity protects information from being altered or corrupted, ensuring it remains accurate and trustworthy. Availability makes sure authorized users can access the information and systems when needed. When you bundle these three goals into a single concept used to guide security design and evaluation, you get the CIA Triad. The other terms refer to different ideas: a threat actor is someone who carries out an attack, an attack vector is the path or method used to breach a system, and modular arithmetic is a mathematical tool often used in cryptography but not a framework for security objectives.
