- Evidence the mechanism is protected from the domains it separates, including from privileged users within them · Identity provider / directory
- Test results demonstrating the separation and the handling of mechanism failure · Source control / CI pipeline

- Configuration showing the policy enforced between the domains · Policy repository / GRC workspace
First move
Common gaps auditors find
- Separation mechanism runs at the same privilege as the workloads, so a compromise of either defeats it
- Patching of the separation mechanism treated as routine, leaving known escape paths open
- Failure behaviour untested, so mechanism failure silently merges the domains
