PS.3.1: Securely archive the necessary files and supporting data (e.g., integrity verification information, provenance data) to be retained for each software release.
Example 1: Store the release files, associated images, etc. in repositories following the organization’s established policy. Allow read-only access to them by necessary personnel and no access by anyone else.
Example 2: Store and protect release integrity verification information and provenance data, such as by keeping it in a separate location from the release files or by signing the data.
