# Server Security Audit

Use this skill for server security audits and reversible hardening plans across SSH, firewall, users, services, file permissions, and update posture.

## Routing

- Start here to confirm scope, safety boundaries, and the minimum workflow.
- Load `references/full-guide.md` before executing detailed commands, applying templates, or relying on examples from this skill.
- Keep the work limited to the user-requested target; do not add adjacent improvements unless the user asks.

## Quick Workflow

1. Confirm the target, available context, constraints, and done-when signal.
2. Read the relevant section of `references/full-guide.md` for task-specific details.
3. Execute the smallest reversible action that satisfies the request.
4. Verify with read-only evidence first, then document every applied change with rollback commands and post-change validation.
5. Report changed files, commands run, evidence collected, and any remaining risk.
