* Use PAM_DIRECTORY variable where appropriate * Skip checking FreeBSD/NetBSD pam.d/README as a PAM file FreeBSD and NetBSD install a README file in /etc/pam.d. Attempting to check this file as a PAM file just generates a lot of garbage exceptions in the log. * Handle 'include' as a PAM control-flag OpenPAM and some versions of Linux PAM can have a configuration where the control-flag is 'include'. Skip further processing as these files will be processed separately. * Add missing commonly seen specific PAMs Add some missing commonly seen specific PAMs from FreeBSD, NetBSD, and OS X/macOS. The OS X/macOS PAMs were taken from a 10.5 (Leopard) and 10.10 (Yosemite) system respectively. Both FreeBSD and NetBSD come with a pam_ssh PAM. Add a warning when found confitured as it presents a potential security risk (see pam_ssh(8) on FreeBSD/NetBSD).

Lynis - Security auditing and hardening tool, for UNIX-based systems.
Lynis is a security auditing for UNIX derivatives 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. Lynis was commonly used by people in the "blue team" to assess the security defenses of their systems. Nowadays, penetration testers also have Lynis in their toolkit.
We believe software should be simple, updated on a regular basis, and open. You should be able to trust, understand, and have the option to change the software. Many agree with us, as the software is being used by thousands every day to protect their systems.
Goals
The main goals are:
- Automated security auditing
- Compliance testing (e.g. ISO27001, PCI-DSS, HIPAA)
- Vulnerability detection
The software (also) assists with:
- Configuration management
- Software patch management
- System hardening
- Penetration testing
- Intrusion detection
Audience
Typical users of the software:
- System administrators
- Auditors
- Security officers
- Security professionals
Installation
Git
-
Clone or download the project files (no compilation nor installation is required) ;
git clone https://github.com/CISOfy/lynis -
Execute:
./lynis audit system
If you want to run the software as root, we suggest changing the ownership of the files. Use chown -R 0:0 to recursively alter the owner and group and set it to user ID 0 (root).
Package
Stable releases of Lynis are packaged and made available as RPM or DEB package. The CISOfy software repository can be used to install Lynis on systems running :
CentOS, Debian, Fedora, OEL, openSUSE, RHEL, Ubuntu, and others.
Enterprise version
This software component is also part of an enterprise solution. Same quality, yet with more functionality.
Focus areas include compliance (PCI DSS, HIPAA, ISO27001, and others). The Enterprise version comes with:
- a web interface and features a dashboard ;
- hardening snippets ;
- and an improvement plan.
