<p style="margin-left:11%; margin-top: 1em">openshift_app_selinux
&minus; Security Enhanced Linux Policy for the openshift_app
processes</p>

<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>



<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the openshift_app processes via flexible
mandatory access control.</p>

<p style="margin-left:11%; margin-top: 1em">The
openshift_app processes execute with the openshift_app_t
SELinux type. You can check if you have these processes
running by executing the <b>ps</b> command with the
<b>&minus;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 openshift_app_t</b></p>

<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>


<p style="margin-left:11%; margin-top: 1em">The
openshift_app_t SELinux type can be entered via the
<b>crontab_exec_t, user_cron_spool_t</b> file types.</p>

<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the openshift_app_t domain are the
following:</p>


<p style="margin-left:11%; margin-top: 1em">/usr/bin/(f)?crontab,
/usr/bin/at, /usr/sbin/fcronsighup,
/usr/libexec/fcronsighup, /var/spool/at(/.*)?,
/var/spool/cron, /var/spool/cron/[^/]+</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>&minus;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
openshift_app policy is very flexible allowing users to
setup their openshift_app processes in as secure a method as
possible.</p>

<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for openshift_app:</p>


<p style="margin-left:11%; margin-top: 1em"><b>openshift_app_t</b></p>

<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a openshift_app_t</b> can be used to
make the process type openshift_app_t permissive. SELinux
does not deny access to permissive process types, but the
AVC (SELinux denials) messages are still generated.</p>

<h2>MCS Constrained
<a name="MCS Constrained"></a>
</h2>


<p style="margin-left:11%; margin-top: 1em">The SELinux
process type openshift_app_t is an MCS (Multi Category
Security) constrained type. Sometimes this separation is
referred to as sVirt. These types are usually used for
securing multi-tenant environments, such as virtualization,
containers or separation of users. The tools used to launch
MCS types, pick out a different MCS label for each process
group.</p>

<p style="margin-left:11%; margin-top: 1em">For example one
process might be launched with openshift_app_t:s0:c1,c2, and
another process launched with openshift_app_t:s0:c3,c4. The
SELinux kernel only allows these processes can only write to
content with a matching MCS label, or a MCS Label of s0. A
process running with the MCS level of s0:c1,c2 is not
allowed to write to content with the MCS label of
s0:c3,c4</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.
openshift_app policy is extremely flexible and has several
booleans that allow you to manipulate the policy and run
openshift_app with the tightest access possible.</p>

<p style="margin-left:11%; margin-top: 1em">If you want to
determine whether crond can execute jobs in the user domain
as opposed to the the generic cronjob domain, you must turn
on the cron_userdomain_transition boolean. Enabled by
default.</p>

<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
cron_userdomain_transition 1</b></p>

<p style="margin-left:11%; margin-top: 1em">If you want to
deny any process from ptracing or debugging any other
processes, you must turn on the deny_ptrace boolean.
Disabled by default.</p>

<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
deny_ptrace 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>MANAGED FILES
<a name="MANAGED FILES"></a>
</h2>


<p style="margin-left:11%; margin-top: 1em">The SELinux
process type openshift_app_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>
