CCSP Legal, Risk, and Compliance Practice Question
Which CSA STAR tier involves a third-party assessment against ISO 27001?
⚠ Common exam trap
ISC2 often tests the misconception that Tier 2 is the 'self-assessment' tier, confusing it with Tier 1, or that there is a Tier 4 for peer review, which does not exist in the CSA STAR framework.

Correct answer & explanation
✓
Tier 2 – Third-party assessment
The CSA STAR (Security, Trust, Assurance, and Risk) program has three tiers: Tier 1 (Self-Assessment), Tier 2 (Third-Party Assessment), and Tier 3 (Continuous Monitoring). Tier 2 specifically requires a third-party assessment against the ISO/IEC 27001 standard, where an accredited certification body audits the cloud service provider's Information Security Management System (ISMS) for compliance. This tier provides a higher level of assurance than self-assessment, as it involves independent validation of security controls.
