    About this skill

    Run a full Linux server security audit in seconds. This skill inspects your server across 12 security domains and delivers a severity-rated report with exact fix commands, no manual research needed.

    What gets checked:

    • Kernel CVEs — Copy Fail (CVE-2026-31431), Dirty Frag (CVE-2026-43284/43500), and Fragnesia (CVE-2026-46300), the three critical root escalation vulnerabilities from April–May 2026
    • SSH hardening — PermitRootLogin, PasswordAuthentication, MaxAuthTries, port
    • Firewall — UFW status, default rules, open ports
    • Users & root — UID 0 accounts, empty passwords, sudoers wildcards
    • Fail2ban — installed and active?
    • DNS & hostname — reachable nameservers, correct hostname
    • NTP sync — clock synchronized?
    • Kernel parameters — rp_filter, tcp_syncookies, randomize_va_space
    • Unnecessary services — telnet, rsh, FTP, and other legacy daemons
    • File permissions — world-writable files, unexpected SUID binaries
    • System patches — pending security updates

    WSL2 support included. The skill automatically detects WSL and skips incompatible checks (UFW, auditd, NTP) with a clear explanation of what was skipped and why.

    Output is a structured report with 🔴 Critical / 🟠 High / 🟡 Medium / 🟢 OK ratings and copy-paste fix commands for every finding.
