Trust Services Criteria — the AICPA criteria (Security, Availability, Processing Integrity, Confidentiality, Privacy) that a SOC 2 report is evaluated against.
The Trust Services Criteria are published by the AICPA. Security is required for every SOC 2 report; the other four categories (Availability, Processing Integrity, Confidentiality, Privacy) are optional and chosen based on what's relevant to the service being audited. Each category breaks down into Common Criteria and points of focus.
