<p style="margin-left:11%; margin-top: 1em">nagios_eventhandler_plugin_selinux
− Security Enhanced Linux Policy for the
nagios_eventhandler_plugin processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the nagios_eventhandler_plugin processes via
flexible mandatory access control.</p>
<p style="margin-left:11%; margin-top: 1em">The
nagios_eventhandler_plugin processes execute with the
nagios_eventhandler_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_eventhandler_plugin_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The
nagios_eventhandler_plugin_t SELinux type can be entered via
the <b>nagios_eventhandler_plugin_exec_t</b> file type.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the nagios_eventhandler_plugin_t domain
are the following:</p>
<p style="margin-left:11%; margin-top: 1em">/usr/lib/icinga/plugins/eventhandlers(/.*),
/usr/lib/nagios/plugins/eventhandlers(/.*)</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_eventhandler_plugin policy is very flexible allowing
users to setup their nagios_eventhandler_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_eventhandler_plugin:</p>
<p style="margin-left:11%; margin-top: 1em"><b>nagios_eventhandler_plugin_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a nagios_eventhandler_plugin_t</b>
can be used to make the process type
nagios_eventhandler_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_eventhandler_plugin policy is extremely flexible and
has several booleans that allow you to manipulate the policy
and run nagios_eventhandler_plugin with the tightest access
possible.</p>
<p style="margin-left:11%; margin-top: 1em">If you want to
deny user domains applications to map a memory region as
both executable and writable, this is dangerous and the
executable should be reported in bugzilla, you must turn on
the deny_execmem boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
deny_execmem 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
control the ability to mmap a low area of the address space,
as configured by /proc/sys/vm/mmap_min_addr, you must turn
on the mmap_low_allowed boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
mmap_low_allowed 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
disable kernel module loading, you must turn on the
secure_mode_insmod boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
secure_mode_insmod 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow unconfined executables to make their heap memory
executable. Doing this is a really bad idea. Probably
indicates a badly coded executable, but could indicate an
attack. This executable should be reported in bugzilla, you
must turn on the selinuxuser_execheap boolean. Disabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
selinuxuser_execheap 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow unconfined executables to make their stack executable.
This should never, ever be necessary. Probably indicates a
badly coded executable, but could indicate an attack. This
executable should be reported in bugzilla, you must turn on
the selinuxuser_execstack boolean. Enabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
selinuxuser_execstack 1</b></p>
<h2>MANAGED FILES
<a name="MANAGED FILES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The SELinux
process type nagios_eventhandler_plugin_t can manage files
labeled with the following file types. The paths listed are
the default paths for these file types. Note the processes
UID still need to have DAC permissions.</p>
<p style="margin-left:11%; margin-top: 1em"><b>file_type</b></p>
<p style="margin-left:11%; margin-top: 1em">all files on
the system</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_eventhandler_plugin policy is very flexible allowing
users to setup their nagios_eventhandler_plugin processes in
as secure a method as possible.</p>
<p style="margin-left:11%; margin-top: 1em"><b>STANDARD
FILE CONTEXT</b></p>
<p style="margin-left:11%; margin-top: 1em">SELinux defines
the file context types for the nagios_eventhandler_plugin,
if you wanted to store files with these types in a different
paths, you need to execute the semanage command to specify
alternate labeling and then use restorecon to put the labels
on disk.</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
fcontext -a -t nagios_eventhandler_plugin_tmp_t
’/srv/mynagios_eventhandler_plugin_content(/.*)?’
<br>
restorecon -R -v
/srv/mynagios_eventhandler_plugin_content</b></p>
<p style="margin-left:11%; margin-top: 1em">Note: SELinux
often uses regular expressions to specify labels that match
multiple files.</p>
<p style="margin-left:11%; margin-top: 1em"><i>The
following file types are defined for
nagios_eventhandler_plugin:</i></p>
<p style="margin-left:11%; margin-top: 1em"><b>nagios_eventhandler_plugin_exec_t</b></p>
<p style="margin-left:11%; margin-top: 1em">- Set files
with the nagios_eventhandler_plugin_exec_t type, if you want
to transition an executable to the
nagios_eventhandler_plugin_t domain. <br>
Paths:</p>
<p style="margin-left:18%;">/usr/lib/icinga/plugins/eventhandlers(/.*),
/usr/lib/nagios/plugins/eventhandlers(/.*)</p>
<p style="margin-left:11%; margin-top: 1em"><b>nagios_eventhandler_plugin_tmp_t</b></p>
<p style="margin-left:11%; margin-top: 1em">- Set files
with the nagios_eventhandler_plugin_tmp_t type, if you want
to store nagios eventhandler plugin temporary files in the
/tmp directories.</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>

settings.</p>
