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