Project Summary
Lynis is an auditing tool for systems running Linux, BSD, or other Unix derivatives. It performs a security scan and determines the hardening state of the machine. Any detected security issues will be provided in the form of a suggestion or warning. Beside security related information it will also scan for general system information, installed packages, and possible configuration errors.
This software assists with automated auditing, compliance audits (PCI DSS, HIPAA, etc), system hardening, software patch management, vulnerability detection, and malware scanning. It can be run without prior installation.
Lynis is typically used by system administrators and security professionals.
