CIA Triad, Services & Mechanisms

Introduces confidentiality, integrity, and availability as the fundamental goals that drive every security decision.

Step 1 / 5

CIA Triad, Services & Mechanisms: the core idea

Introduces confidentiality, integrity, and availability as the fundamental goals that drive every security decision. The key thing to notice is: Confidentiality (data secrecy & need-to-know). A useful example is 2024 Change Healthcare ransomware: availability & confidentiality loss. Do not treat this as a vocabulary item; the point is to use it to reason about a new situation.
