Lynis v2.4.0 Released

Lynis v2.4.0 Released

Lynis is a security auditing for UNIX derivatives like Linux, Mac OS X, BSD, and Solaris. It performs an in-depth security scan on the system itself, with the goal to detect issues and provide tips for further system hardening. It will also scan for general system information, vulnerable software packages, and possible configuration issues. Lynis is commonly used by people in the “blue team” to assess the security defenses of their systems.

Main goals:

  • Automated security auditing
  • Compliance testing (e.g. PCI-DSS, HIPAA)
  • Vulnerability detection

The software aims to also assist with:

  • Configuration management
  • Software patch management
  • System hardening
  • Penetration testing
  • Malware scanning
  • Intrusion detection
