SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Linux environments often run diverse configuration files across services (nginx, sshd, systemd, firewalls, etc.) that, if misconfigured, can expose security risks, degrade performance, or violate compliance requirements. This Skill helps you audit those files for security issues, misconfigurations, and performance gaps, providing actionable insights.

Core Features & Use Cases

  • Multi-file/config-type auditing: supports nginx, apache2, sshd_config, systemd units, iptables/nftables, firewalld, fail2ban, sudoers, /etc/security/limits.conf, sysctl.conf, pg_hba.conf, mysql/my.cnf, redis.conf, and more.
  • Structured findings with severity ratings, explanations, and ready-to-apply fixes.
  • Report generation and patch-ready configuration snippets for hardening and compliance.

Quick Start

Paste the Linux config content or specify the config type you want audited, and I will return a security-focused findings report.

Does the Linux config audit support systemd units and fail2ban configurations?▼

Yes, the Linux config audit supports systemd units and fail2ban configurations. It reviews these files alongside sudoers and apache2 configs to detect security vulnerabilities, performance gaps, and compliance violations.

How do I generate a patch-ready snippet to fix nginx security risks?▼

To generate a patch-ready snippet to fix nginx security risks, paste your configuration content for auditing. The process evaluates the file for misconfigurations and returns a structured report containing recommended fixes and the snippet.
