Lynis: Security auditing and hardening tool for UNIX-based systems
lynis
Lynis is a security auditing tool for systems based on UNIX like Linux, macOS, BSD, and others. It performs an in-depth security scan and runs on the system itself. The primary goal is to test security defenses and provide tips for further system hardening. It will also scan for general system information, vulnerable software packages, and possible configuration issues. System administrators and auditors commonly used Lynis to assess the security defenses of their systems. Besides the “blue team,” nowadays penetration testers also have Lynis in their toolkit.
