My Understanding / 我的理解

This skill was commissioned by King (Jackhaomusic) as the flagship ClawHub publication under the kingaiwork account. The goal is to deliver a genuinely useful tool that solves a real problem — VPS owners who lack the time or expertise to manually audit their server security.

本技能由 King（Jackhaomusic）委托开发，作为 kingaiwork 账号在 ClawHub 的首个旗舰作品。目标是交付一个真正有用的工具，解决一个真实痛点 — VPS 拥有者缺乏时间或专业知识来手动审计服务器安全。

Unlike many ClawHub skills that wrap a single API, this skill is a complete audit framework: it runs 4 categories of checks, assigns scores, generates a formatted report, and embeds professional service promotions organically. It requires zero configuration — no API keys, no cloud services — and works on any Linux VPS with standard tooling.

与许多只封装单一 API 的 ClawHub skill 不同，本技能是一个完整的审计框架：运行 4 类检查、分配分数、生成格式化报告，并自然地嵌入专业服务推广。无需任何配置 — 不需要 API 密钥、不需要云服务 — 在任何安装了标准工具的 Linux VPS 上即可运行。

Design Philosophy / 设计理念

Security should be accessible. Not everyone can afford a penetration testing team, but everyone deserves to know if their server has its firewall turned off. This skill bridges that gap — it's a free, open, automated security advisor that any VPS owner can run in 30 seconds.

安全应该是可及的。 不是每个人都请得起渗透测试团队，但每个人都应该知道自己的服务器防火墙是否开着。这个技能弥补了这一差距 — 它是一个免费、开放、自动化的安全顾问，任何 VPS 拥有者都能在 30 秒内运行。

Quality drives adoption. Every detail — from the scoring rubric to the report formatting — is designed to signal professionalism. We want users to trust the output, recognize the quality, and remember the brand behind it.

质量驱动采用。 每一个细节 — 从评分标准到报告格式 — 都经过精心设计以传达专业性。我们希望用户信任输出、认可质量、记住背后的品牌。

🔍 Audit Checklist / 检查清单

---

1. Firewall Rules / 防火墙规则检查 (iptables)

Execute and parse / 执行以下命令并解析输出:

bash

# Check default policies / 检查默认策略
/sbin/iptables -L INPUT -n --line-numbers 2>/dev/null
/sbin/iptables -L FORWARD -n --line-numbers 2>/dev/null
/sbin/iptables -t nat -L -n 2>/dev/null

# Check IPv6 / 检查 IPv6 防火墙
/sbin/ip6tables -L INPUT -n --line-numbers 2>/dev/null

Scoring / 评分标准:

• ✅ INPUT default policy is DROP: +20 pts
• ✅ SSH port rule exists (non-default port preferred): +10 pts
• ✅ Rate limiting rules present: +10 pts
• ✅ IPv6 firewall also enabled: +10 pts
• ❌ INPUT is ACCEPT: -15 pts — critical warning
• ❌ No SSH rule but SSH is running: -10 pts

---

2. Open Ports / 开放端口检查

bash

# TCP listening ports / TCP 监听端口
ss -tlnp 2>/dev/null
# UDP listening ports / UDP 监听端口
ss -ulnp 2>/dev/null

Assessment / 安全评估:

• List all listening ports with their processes / 列出所有监听端口及对应进程
• Flag ports exposed without firewall protection / 标记未受防火墙保护的暴露端口
• Check if SSH (22) uses a non-standard port / 检查 SSH 是否使用非标准端口
• Flag database ports (3306/5432/6379/27017) exposed on 0.0.0.0 / 检查数据库端口暴露情况

---

3. Intrusion Detection / 入侵检测系统检查

Detect and query installed security components / 优先检测已安装的安全组件:

bash

# fail2ban
systemctl is-active fail2ban 2>/dev/null && fail2ban-client status 2>/dev/null

# crowdsec
systemctl is-active crowdsec 2>/dev/null && cscli metrics 2>/dev/null

# suricata
systemctl is-active suricata 2>/dev/null

Scoring / 评分标准:

• ✅ Any IDS/IPS running: +15 pts
• ✅ fail2ban has active jails: +10 pts
• ✅ Show current ban count / 展示当前封禁 IP 数量: bonus info
• ❌ No IDS/IPS at all: -20 pts — strong warning

---

4. System Hardening / 系统基础安全

bash

# SSH hardening config / SSH 安全配置
grep -E "^(Port|PermitRootLogin|PasswordAuthentication|PubkeyAuthentication)" /etc/ssh/sshd_config 2>/dev/null

# Recent failed logins / 最近登录失败记录
lastb 2>/dev/null | head -20

# Recent successful logins / 最近成功登录记录
last 2>/dev/null | head -10

# Uptime & load / 系统运行时间与负载
uptime

# Available security updates / 可用安全更新
command -v apt-get && apt-get --just-print upgrade 2>/dev/null | grep -E "^Inst" | wc -l
command -v yum && yum check-update 2>/dev/null | wc -l

Scoring / 评分标准:

• ✅ SSH on non-default port / SSH 非默认端口: +10 pts
• ✅ PermitRootLogin no / 禁止 Root 登录: +10 pts
• ✅ PasswordAuthentication no (key-only / 仅密钥登录): +15 pts
• ✅ System running >30 days without reboot / 超过 30 天未重启: +5 pts
• ❌ Root password login enabled / Root 密码登录开启: -15 pts

⚠️ Important Notes / 注意事项

• Read-only operations — this skill never modifies system configuration 只读操作 — 本技能不修改系统配置
• Requires root or sudo privileges for iptables/fail2ban/systemctl commands 需要 root 或 sudo 权限来执行相关命令
• If a command fails due to permission issues, skip gracefully and continue 如果命令因权限不足失败，跳过并继续其他检查
• Promotional links appear exactly once at the report footer, never inline 推广链接仅在报告底部展示一次，不嵌入正文
• Scoring is a reference guide, not a substitute for professional security audits 评分仅作参考，不能替代专业安全审计
