<a href="toolchain.html">toolchain</a> and
<a href="samhain.html">samhain</a> before running tests.</p>
<p>Mount some filesystems in read only</p>

$ sudo prt-get depinst checksec lynis

<p>Lynis gives a view of system overall configuration, without changing
default profile it runs irrelevant tests. Create a lynis profile by
coping default one and run lynis;</p>
<pre>
$ sudo cp /etc/lynis/default.prf /etc/lynis/custom.prf
$ sudo lynis configure settings color=yes
$ sudo lynis show settings
$ sudo lynis show profile
</pre>
<pre>
$ lynis audit system > lynis_report
$ mv /tmp/lynis.log .
$ mv /tmp/lynis-report.dat .
</pre>
<p>Add unnecessary tests to profile to have less noise.</p>
