DEV-08 Logging of Changes

3 sub-criteria: 2 basic, 1 additional

Changed since C5:2020 · formerly DEV-07

Basic criterion

Linguistic adaptation without changes in content.

Additional criterion

Additional criterion newly included.

Wording in C5:2020

Basic criterion

System components and tools for source code management and software deployment that are used to make changes to system components of the cloud service in the production environment are subject to a role and rights concept according to IDM-01 and authorisation mechanisms. They must be configured in such a way that all changes are logged and can therefore be traced back to the individuals or system components executing them.

All changes since C5:2020

Basic criterion

DEV-08.01B

System components for version control and software deployment that are used to manage changes to system components of the cloud service in the production environment are subject to a role and rights framework according to IAM-01 and authorisation mechanisms.

DEV-08.02B

The configuration of these system components ensures that all changes performed by the cloud service provider to system components in the production environment are recorded and can be traced back to the individuals or system components contributing to their development, deployment or implementation.

Supplementary information

If the change has external contribution (e.g. use of third-party products, libraries), tracing back individual changes in the development is often not possible. In that case it is sufficient to record the external contribution in the software component list or Software Bill of Materials (SBOM, cf. DEV-13.01B). In addition to that, depending on the nature of the external contribution, the criterion for Outsourcing of the Development (cf. DEV-02) and the criteria for Control and Monitoring of Service Providers and Suppliers (SSO) may apply.

Additional criterion

DEV-08.01AC

Additional, complementing

The cloud service provider enforces the role and rights framework by monitoring the changes made to system components of the cloud service in the production environment. Timely and appropriate remediation measures address any deviations identified during monitoring.
