Criteria
- Start from upstream OpenSSH release notes and local distro policy.
- Separate authentication, authorization, network exposure, and audit logging.
- Prefer reversible configuration changes and documented rollback.
Limitations
This is operational guidance, not a vulnerability advisory or a replacement for distro security notices.
