About:
Lynis is a comprehensive security auditing tool for UNIX-based systems that performs hundreds of individual security checks. It scans for system configurations, software vulnerabilities, and compliance issues to identify security weaknesses and provide actionable hardening recommendations. The tool is non-intrusive and suitable for both automated security audits and manual system assessments.
Key Features:
  • Comprehensive security scanning with hundreds of tests
  • Detailed remediation guidance for discovered issues
  • Support for Linux, macOS, BSD, and Solaris systems
  • Low-impact, non-intrusive scanning methodology
  • Automated compliance checking and reporting
Use Cases:
  • System hardening and security baseline verification
  • Compliance auditing for security standards like CIS benchmarks
  • Automated security monitoring in CI/CD pipelines
  • Pre-deployment security assessments
Alternatives:
  • OpenSCAP – More compliance-focused with NIST-certified scanner, but Lynis is lighter and more user-friendly
  • rkhunter – Rootkit detection specialist, while Lynis provides broader system security auditing
  • chkrootkit – Focused on rootkit detection only, Lynis offers comprehensive security assessment
