Are traditional infosec assurance tools outdated? Many cloud customers think so. They see that technology changes quickly, and products are frequently evolving with continuous integration and deployment. Therefore, a certification obtained once a year after a third-party audit is not asufficient source of assurance anymore. It’s time to move from “point-in-time” assurance to continuous assurance. This change requires moving away from manual audits and instead building automated tools that continuously assess the effectiveness of an information system. In other words, it’s time to move to the world of security metrics.

There is no standard reference for the continuous auditing of cloud services that supports security metrics in a way that is comparable to what the CSA CCM or ISO/IEC 27002 does for security controls. To address this gap, CSA launched the Continuous Audit Metrics Working Group in early 2020 to build the first catalog of security metrics for the cloud. We have released the first version of this catalog that contains an initial set of 34 security metrics, each mapped to the CCM v4. These metrics aim to support internal CSP governance, risk, and compliance (GRC) activities and provide a helpful baseline for service-level agreement transparency. 

Topics covered: 

• Explanation of security metrics
• How to measure the effectiveness of an information system
• How to enable continuous auditing
• Catalog listing the 34 metrics
