Cloud Control Matrix is the core component used in providing the cloud security compliance check.
CCM v3.0.1 was initially released 6 years ago. CSA determined that it is time to revise and provide the community with vendor-neutral security and privacy control framework.
More controls are added and more guidelines will be extended from the CCM v4.
CCM v4 can be downloaded from https://cloudsecurityalliance.org/research/cloud-controls-matrix/
CCM Implementation Guidelines will be published Q2, 2021
CCM Auditing Guidelines will be published Q3, 2021
