The primary purpose of the Open Certification Framework (OCF) for the CSA STAR program is to provide global, accredited, and trusted certification of the cloud service provider. According to the CSA website1, the OCF is an industry initiative to allow global, trusted independent evaluation of cloud providers. It is a program for flexible, incremental and multi-layered cloud provider certification and/or attestation according to the Cloud Security Alliance’s industry leading security guidance and control framework. The OCF aims to address the gaps within the IT ecosystem that are inhibiting market adoption of secure and reliable cloud services. The OCF also integrates with popular third-party assessment and attestation statements developed within the public accounting community to avoid duplication of effort and cost. The OCF manages the foundation that runs and monitors the CSA STAR Certification program, which is an assurance framework that enables cloud service providers to embed cloud-specific security controls. The STAR Certification program has three levels of assurance, each based on a different type of audit or assessment: Level 1: Self-Assessment, Level 2: Third-Party Audit, and Level 3: Continuous Auditing. The OCF also oversees the CSA STAR Registry, which is a publicly accessible repository that documents the security controls provided by various cloud computing offerings2. The OCF helps consumers to evaluate and compare their providers’ resilience, data protection, privacy capabilities, and service portability. It also helps providers to demonstrate their compliance with industry standards and best practices.
