What is the Cloud Security Alliance Cloud Controls Matrix (CCM)?

The Cloud Security Alliance Cloud Controls Matrix (CCM) is indeed an inventory of cloud service security controls that are organized into separate security domains. This framework is designed to help organizations assess the security posture of their cloud service providers and their services. By categorizing these controls into distinct domains, the CCM enables organizations to understand and implement security measures that address specific areas of concern, such as data security, identity and access management, and incident management.

This organization allows for a more structured approach to evaluating the security practices of cloud services, ensuring that users can systematically address diverse security requirements and compliance obligations. The clear delineation of controls into separate domains simplifies the task of aligning security practices with risk management frameworks and regulatory guidelines.

Other options, while related to cloud security, do not accurately represent the nature of the CCM. For instance, the idea of a set of software development life cycle requirements or regulatory requirements does not encompass the matrix's intent, which is focused specifically on security controls rather than development processes or compliance mandates. Additionally, the notion of a hierarchy suggests a structuring of controls in a ranked fashion, which is not the primary feature of the CCM. Instead, it emphasizes distinct security domains to facilitate a complete view of necessary security practices in cloud environments.
