This test was previously measuring the number of bytes (wc -c) in the exported JSON which is likely not what was intended and will lead to false positives anytime the number of bytes exceeds 16. The export feature is poorly documented and requires the jansson package on the target system to export as JSON - which may not always be the case. Lastly, 16 is an arbitrary and uncessarily high number. A simple workstation firewall can have only 3 rules and be effective. This commit makes use of 'nft list ruleset' instead of the export command, strips out blank lines as well as table & chain headers before measuring the number of lines in the output. Any result with more than 3 rules is now considered non-empty. This is more consistent with the equivalent iptables test case. |

Lynis - Security auditing and hardening tool, for UNIX-based systems.
Lynis is a security auditing for system 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. Lynis was commonly used by system administrators and auditors to assess the security defenses of their systems. Besides the "blue team", 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 and asset management
- Software patch management
- System hardening
- Penetration testing (privilege escalation)
- Intrusion detection
Audience
Typical users of the software:
- System administrators
- Auditors
- Security officers
- Penetration testers
- Security professionals
Installation
Git
-
Clone or download the project files (no compilation nor installation is required) ;
git clone https://github.com/CISOfy/lynis
-
Execute:
cd lynis; ./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.
