The CSA STAR Certification is based on criteria outlined in the Cloud Security Alliance (CSA) Cloud Controls Matrix (CCM) in addition to ISO/IEC 27001 implementation. The CCM is a cybersecurity control framework for cloud computing that covers 17 domains and 197 control objectives that address all key aspects of cloud technology. ISO/IEC 27001 is a standard for information security management systems that specifies the requirements for establishing, implementing, maintaining, and continually improving an information security management system within the context of the organization. The CSA STAR Certification demonstrates that a cloud service provider conforms to the applicable requirements of ISO/IEC 27001, has addressed issues critical to cloud security as outlined in the CCM, and has been assessed against the STAR Capability Maturity Model for the management of activities in CCM control areas1. The CSA STAR Certification is a third-party independent assessment of the security of a cloud service provider and provides a high level of assurance and trust to customers2.
