This control specification aligns with the concept of independent audits, which are crucial for verifying that an organization adheres to its established policies, standards, procedures, and compliance obligations. The requirement for these reviews and assessments to be performed at least annually ensures ongoing compliance and the ability to address any areas of nonconformity. Independent audits provide an objective assessment and are essential for maintaining transparency and trust in the cloud services provided.
References = The Cloud Controls Matrix (CCM) specifically mentions the need for independent assessments to be conducted annually as part of the Audit Assurance and Compliance domain, which is detailed in the CCM's guidelines and related documents provided by the Cloud Security Alliance (CSA)12.
