Cybersecurity Property

Also known as: CIA triad, Security property

Definition

Cybersecurity Property: Confidentiality, integrity, availability, authenticity (or extensions) protected on each asset. A cybersecurity property is the security attribute that must hold for an asset.

Where this matters: ISO/SAE 21434 Consulting

The CIA triad (confidentiality, integrity, availability) is the baseline; ISO/SAE 21434 adds authenticity, non-repudiation, and authorisation where the analysis warrants. The asset–property pair is the unit a damage scenario then references.
