Lynis: Open-source security auditing tool
Lynis is a comprehensive open-source security auditing tool for UNIX-based systems, including Linux, macOS, and BSD.
Hardening with Lynis
Lynis conducts a thorough security examination of the system directly. Its main objective is to evaluate security measures and recommend enhancing system hardening. The tool also checks for general system details, identifies vulnerable software packages, and detects potential configuration problems.
Lynis is developed using shell script, a flexible scripting language compatible with all Linux systems or those operating on a UNIX-based OS. Most system administrators find it straightforward to develop custom tests for Lynis, a particularly beneficial feature for those interested in creating personalized tests or plugins.
