<h2>NAME
<a name="NAME"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">sandbox_min_client_selinux
− Security Enhanced Linux Policy for the
sandbox_min_client processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the sandbox_min_client processes via flexible
mandatory access control.</p>
<p style="margin-left:11%; margin-top: 1em">The
sandbox_min_client processes execute with the
sandbox_min_client_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 sandbox_min_client_t</b></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
sandbox_min_client policy is very flexible allowing users to
setup their sandbox_min_client processes in as secure a
method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for sandbox_min_client:</p>
<p style="margin-left:11%; margin-top: 1em"><b>sandbox_min_client_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a sandbox_min_client_t</b> can be
used to make the process type sandbox_min_client_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.
sandbox_min_client policy is extremely flexible and has
several booleans that allow you to manipulate the policy and
run sandbox_min_client 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>
<h2>MANAGED FILES
<a name="MANAGED FILES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The SELinux
process type sandbox_min_client_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>fusefs_t</b></p>
<p style="margin-left:11%; margin-top: 1em">/var/run/user/[0-9]+/gvfs</p>
<p style="margin-left:11%; margin-top: 1em"><b>mozilla_plugin_tmpfs_t</b></p>
<p style="margin-left:11%; margin-top: 1em"><b>sandbox_file_t</b></p>
<p style="margin-left:11%; margin-top: 1em"><b>sandbox_min_client_tmpfs_t</b></p>
<p style="margin-left:11%; margin-top: 1em"><b>security_t</b></p>
<p style="margin-left:11%; margin-top: 1em">/selinux</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>
