Lynis is an open source security monitoring tool. Used by system administrators, security professionals, and penetration testers to evaluate the security defense of Linux and UNIX-based systems.
It runs on the host itself, so it performs more extensive security scans than vulnerability scanners.
Supported operating systems
Lynis runs on almost all UNIX-based systems and versions, including:
It even runs on Raspberry Pi or QNAP devices.
Lynis is lightweight and easy to use. The installation is optional: just copy it to a system and use the "./lynis audit system" command to start the security scan.
Performs hundreds of individual tests. Each test helps determine the security status of the system. What happens during a scan with Lynis:
- Identify the operating system
- Search for available tools and utilities
- Check for Lynis updates
- Perform tests with enabled plugins
- Perform safety tests by category
- Report the status of the security scan
In addition to the data displayed on the screen, all technical details about the scan are stored in a file καταγραφής. Τυχόν ευρήματα (προειδοποιήσεις, προτάσεις, data collection) are stored in a reference file.
