name: security-network-hardening description: Audit and harden an OpenClaw host and its network exposure. Use for security checks, hardening, firewall setup, network exposure review, metrics endpoint restriction, OpenClaw gateway security fixes, or step-by-step remediation on a Linux host running OpenClaw.

Security + Network Hardening

Audit first, then harden with explicit approval. Keep this file short; read the references when needed.

Core rules

• Start read-only unless the user explicitly asks for fixes.
• Require confirmation before any state-changing action.
• Preserve current management access; do not break SSH/RDP/VNC.
• Prefer exact findings over generic advice.
• After workspace edits, commit them.

Read-only baseline

Run:

uname -a
cat /etc/os-release
id
ss -ltnup 2>/dev/null || ss -ltnp 2>/dev/null
openclaw security audit --deep
openclaw update status
openclaw status --deep

If firewall state matters, also run:

ufw status verbose || true
firewall-cmd --state 2>/dev/null || true
nft list ruleset 2>/dev/null || true

Priorities

Check for these first: 1. elevated wildcard access in tools.elevated.allowFrom.* 2. writable credentials directories 3. missing gateway auth rate limiting 4. broad or unclear listening ports 5. metrics endpoints exposed too widely 6. ineffective custom gateway.nodes.denyCommands 7. workspace skill symlink escapes

Fix patterns

Read these only when relevant: - UFW/firewall workflow: references/ufw-playbook.md - OpenClaw config fixes: references/openclaw-fix-patterns.md

Artifact generation

When the user wants generated files, create: - firewall-rules.md - apply-firewall.sh - scripts/rollback-firewall.sh - scripts/verify-firewall.sh

Safe firewall order

1. Confirm allowed source subnet/IPs.
2. Add SSH rule first if SSH is in use.
3. Apply LAN-only and single-host rules.
4. Verify from expected clients.
5. Re-check ufw status verbose and ss -ltnp.

Verification

After fixes, verify with:

openclaw security audit --deep
openclaw gateway status
python3 -m json.tool ~/.openclaw/openclaw.json >/dev/null
sudo ufw status verbose
ss -ltnp

Success means: - no critical audit findings - no warning audit findings when practical - gateway reachable - required ports reachable only from approved sources

质量较好。这个 Skill 把安全审计和防火墙加固的流程梳理得很清晰，核心规则设计合理，文档结构简洁易读，脚本工具也比较实用。不过缺少使用示例，对新手不太友好，遇到复杂问题可能不太好找到具体答案。整体来说是个靠谱的安全加固工具，适合有经验的用户使用。
