− Security Enhanced Linux Policy for the openvpn
processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the openvpn processes via flexible mandatory
access control.</p>
<p style="margin-left:11%; margin-top: 1em">The openvpn
processes execute with the openvpn_t SELinux type. You can
check if you have these processes running by executing the
<b>ps</b> command with the <b>−Z</b> qualifier.</p>
<p style="margin-left:11%; margin-top: 1em">For
example:</p>
<p style="margin-left:11%; margin-top: 1em"><b>ps -eZ |
grep openvpn_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The openvpn_t
SELinux type can be entered via the <b>openvpn_exec_t</b>
file type.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the openvpn_t domain are the
following:</p>
<p style="margin-left:11%; margin-top: 1em">/usr/sbin/openvpn</p>
<h2>PROCESS TYPES
<a name="PROCESS TYPES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux defines
process types (domains) for each process running on the
system</p>
<p style="margin-left:11%; margin-top: 1em">You can see the
context of a process using the <b>−Z</b> option to
<b>ps</b></p>
<p style="margin-left:11%; margin-top: 1em">Policy governs
the access confined processes have to files. SELinux openvpn
policy is very flexible allowing users to setup their
openvpn processes in as secure a method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for openvpn:</p>
<p style="margin-left:11%; margin-top: 1em"><b>openvpn_t,
openvpn_unconfined_script_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a openvpn_t</b> can be used to make
the process type openvpn_t permissive. SELinux does not deny
access to permissive process types, but the AVC (SELinux
denials) messages are still generated.</p>
<h2>BOOLEANS
<a name="BOOLEANS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux policy
