What is Cloud Security Alliance (CSA) STAR Certification?
The Cloud Security Alliance (CSA) STAR Certification is a third-party independent assessment of a cloud service provider's (CSP) security posture. It leverages the requirements of the ISO/IEC 27001 management system standard and the CSA Cloud Controls Matrix (CCM) to evaluate and document security controls. This certification is designed to enhance transparency and build trust between CSPs and their customers by demonstrating compliance with industry-accepted security standards and best practices.
How Cloud Security Alliance (CSA) STAR Certification Works
The CSA STAR Certification involves a rigorous assessment process that includes:
Self-Assessment (Level 1): This is a complimentary offering where CSPs evaluate and document their security controls using the Consensus Assessments Initiative Questionnaire (CAIQ). The results are publicly available on the CSA STAR Registry.
Third-Party Assessment (Level 2): This involves independent third-party assessments such as CSA STAR Certification and CSA STAR Attestation. These assessments combine established industry standards with criteria specified in the CCM.
Evaluation Process: The assessment includes an evaluation of the CSP’s maturity level across each CCM security domain. Each domain is scored on a specific maturity against five management principles: Communication and Stakeholder Engagement, Policies, Plans and Procedures, Skills and Expertise, Ownership, Leadership, and Management, and Monitoring and Measuring. The maturity level for each domain is then averaged to result in an overall maturity score.
Certification and Reporting: Based on the overall maturity score, a CSP can achieve a bronze, silver, or gold award. The CSP can then register on the CSA STAR Registry as successfully achieving CSA STAR certification.
