[+] Installation
-------------------------------
Lynis doesn't have to be installed, so it can be used directly from a
(removable) disk. If you want the program to be installed, use one of the
following methods:
- Create a custom directory (ie. /usr/local/lynis) and unpack the tarball
(tar xfvz lynis-version.tar.gz) into this directory.
- Create a RPM package by using the lynis.spec file (see web site)
run 'rpmbuild -ta lynis-version.tar.gz' (= build RPM package)
run 'rpm -ivh <filename>' (= install RPM package)
See online documentation for detailed instructions.
[+] Supported systems

Since the complexity of auditing different systems and platforms, Lynis is
developed on BSD and Linux.
This tool is tested or confirmed to work with at least:
AIX, Linux, FreeBSD, OpenBSD, macOS, Solaris. See the website for the full
list of tested operating systems.

Lynis to audit systems, but also provides malware scanning, intrusion detection
and has additional guidance. For all features, please see our website:
