<h2>NAME

<p style="margin-left:11%; margin-top: 1em">nagios_mail_plugin_selinux
− Security Enhanced Linux Policy for the
nagios_mail_plugin processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the nagios_mail_plugin processes via flexible
mandatory access control.</p>
<p style="margin-left:11%; margin-top: 1em">The
nagios_mail_plugin processes execute with the
nagios_mail_plugin_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 nagios_mail_plugin_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The
nagios_mail_plugin_t SELinux type can be entered via the
<b>nagios_mail_plugin_exec_t</b> file type.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the nagios_mail_plugin_t domain are the
following:</p>
<p style="margin-left:11%; margin-top: 1em">/usr/lib/nagios/plugins/check_mailq</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
nagios_mail_plugin policy is very flexible allowing users to
setup their nagios_mail_plugin processes in as secure a
method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for nagios_mail_plugin:</p>
<p style="margin-left:11%; margin-top: 1em"><b>nagios_mail_plugin_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a nagios_mail_plugin_t</b> can be
used to make the process type nagios_mail_plugin_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
is customizable based on least access required.
nagios_mail_plugin policy is extremely flexible and has
several booleans that allow you to manipulate the policy and
run nagios_mail_plugin with the tightest access
possible.</p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow all domains to execute in fips_mode, you must turn on
the fips_mode boolean. Enabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
fips_mode 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow confined applications to use nscd shared memory, you
must turn on the nscd_use_shm boolean. Enabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
nscd_use_shm 1</b></p>
<h2>FILE CONTEXTS
<a name="FILE CONTEXTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux
requires files to have an extended attribute to define the
file type.</p>
<p style="margin-left:11%; margin-top: 1em">You can see the
context of a file using the <b>−Z</b> option to
<b>ls</b></p>
<p style="margin-left:11%; margin-top: 1em">Policy governs
the access confined processes have to these files. SELinux
nagios_mail_plugin policy is very flexible allowing users to
setup their nagios_mail_plugin processes in as secure a
method as possible.</p>
<p style="margin-left:11%; margin-top: 1em"><i>The
following file types are defined for
nagios_mail_plugin:</i></p>
<p style="margin-left:11%; margin-top: 1em"><b>nagios_mail_plugin_exec_t</b></p>
<p style="margin-left:11%; margin-top: 1em">- Set files
with the nagios_mail_plugin_exec_t type, if you want to
transition an executable to the nagios_mail_plugin_t
domain.</p>
<p style="margin-left:11%; margin-top: 1em">Note: File
context can be temporarily modified with the chcon command.
If you want to permanently change the file context you need
to use the <b>semanage fcontext</b> command. This will
modify the SELinux labeling database. You will need to use
<b>restorecon</b> to apply the labels.</p>
<h2>COMMANDS
<a name="COMMANDS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
fcontext</b> can also be used to manipulate default file
context mappings.</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
permissive</b> can also be used to manipulate whether or not
a process type is permissive.</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
module</b> can also be used to enable/disable/install/remove
policy modules.</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
boolean</b> can also be used to manipulate the booleans</p>
<p style="margin-left:11%; margin-top: 1em"><b>system-config-selinux</b>
is a GUI tool available to customize SELinux policy
settings.</p>
