</h2>
<p style="margin-left:11%; margin-top: 1em">zabbix_selinux
− Security Enhanced Linux Policy for the zabbix
processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the zabbix processes via flexible mandatory
access control.</p>
<p style="margin-left:11%; margin-top: 1em">The zabbix
processes execute with the zabbix_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 zabbix_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The zabbix_t
SELinux type can be entered via the <b>zabbix_exec_t</b>
file type.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the zabbix_t domain are the
following:</p>
<p style="margin-left:11%; margin-top: 1em">/usr/bin/zabbix_server,
/usr/sbin/zabbix_proxy, /usr/sbin/zabbix_server,
/usr/sbin/zabbix_proxy_mysql, /usr/sbin/zabbix_proxy_pgsql,
/usr/sbin/zabbix_server_mysql,
/usr/sbin/zabbix_server_pgsql,
/usr/sbin/zabbix_proxy_sqlite3,
/usr/sbin/zabbix_server_sqlite3</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 zabbix
policy is very flexible allowing users to setup their zabbix
processes in as secure a method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for zabbix:</p>
<p style="margin-left:11%; margin-top: 1em"><b>zabbix_t,
zabbix_agent_t, zabbix_script_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a zabbix_t</b> can be used to make
the process type zabbix_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. zabbix
policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run zabbix with the
tightest access possible.</p>
<p style="margin-left:11%; margin-top: 1em">If you want to
determine whether zabbix can connect to all TCP ports, you
must turn on the zabbix_can_network boolean. Disabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
zabbix_can_network 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow Zabbix to run su/sudo, you must turn on the
zabbix_run_sudo boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
zabbix_run_sudo 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
dontaudit all daemons scheduling requests (setsched,
sys_nice), you must turn on the daemons_dontaudit_scheduling
boolean. Enabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
daemons_dontaudit_scheduling 1</b></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 system to run with NIS, you must turn on the
nis_enabled boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
nis_enabled 1</b></p>
<h2>PORT TYPES
<a name="PORT TYPES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux defines
port types to represent TCP and UDP ports.</p>
<p style="margin-left:11%; margin-top: 1em">You can see the
types associated with a port by using the following
command:</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
port -l</b></p>
<p style="margin-left:11%; margin-top: 1em">Policy governs
the access confined processes have to these ports. SELinux
zabbix policy is very flexible allowing users to setup their
zabbix processes in as secure a method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
port types are defined for zabbix: <b><br>
zabbix_agent_port_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Default Defined
Ports:</p>
<p style="margin-left:26%;">tcp 10050</p>

<h2>MANAGED FILES

<p style="margin-left:11%; margin-top: 1em">The SELinux
process type zabbix_t can manage files labeled with the

<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

<b>ls</b></p>

<p style="margin-left:11%; margin-top: 1em"><b>EQUIVALENCE
DIRECTORIES</b></p>
<p style="margin-left:11%; margin-top: 1em">zabbix policy
stores data with multiple different file context types under
the /var/lib/zabbix directory. If you would like to store
the data in a different directory you can use the semanage
command to create an equivalence mapping. If you wanted to
store this data under the /srv directory you would execute
the following command:</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
fcontext -a -e /var/lib/zabbix /srv/zabbix <br>
restorecon -R -v /srv/zabbix</b></p>

FILE CONTEXT</b></p>
<p style="margin-left:11%; margin-top: 1em">SELinux defines
the file context types for the zabbix, if you wanted to
store files with these types in a different paths, you need
to execute the semanage command to specify alternate

disk.</p>
