In Google's cloud security model, how does availability contribute to a robust security posture for data?

Restricting data access to authorized users describes confidentiality, the first pillar of the CIA triad, not availability.

Ensuring data meets industry standards relates to compliance and governance requirements, not the availability security principle.

Checking that data is accurate and trustworthy describes integrity, the second pillar of the CIA triad, not availability.

In the CIA triad - Confidentiality, Integrity, and Availability - availability means that systems and data are reliably accessible to authorized users whenever required. Ensuring availability protects against outages and disruptions that would prevent legitimate access. This is a core pillar of a robust security posture alongside confidentiality and integrity.
