<h2>NAME

</h2>
<p style="margin-left:11%; margin-top: 1em">postfix_postdrop_selinux
− Security Enhanced Linux Policy for the
postfix_postdrop processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the postfix_postdrop processes via flexible
mandatory access control.</p>
<p style="margin-left:11%; margin-top: 1em">The
postfix_postdrop processes execute with the
postfix_postdrop_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 postfix_postdrop_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The
postfix_postdrop_t SELinux type can be entered via the
<b>postfix_postdrop_exec_t</b> file type.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the postfix_postdrop_t domain are the
following:</p>
<p style="margin-left:11%; margin-top: 1em">/usr/sbin/postdrop</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
postfix_postdrop policy is very flexible allowing users to
setup their postfix_postdrop processes in as secure a method
as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for postfix_postdrop:</p>
<p style="margin-left:11%; margin-top: 1em"><b>postfix_postdrop_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a postfix_postdrop_t</b> can be used
to make the process type postfix_postdrop_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.
postfix_postdrop policy is extremely flexible and has
several booleans that allow you to manipulate the policy and
run postfix_postdrop 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 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 postfix_postdrop_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>arpwatch_tmp_t</b></p>
<p style="margin-left:11%; margin-top: 1em"><b>krb5_host_rcache_t</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
postfix_postdrop policy is very flexible allowing users to
setup their postfix_postdrop 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 postfix_postdrop, 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 postfix_postdrop_t
’/srv/mypostfix_postdrop_content(/.*)?’ <br>
restorecon -R -v /srv/mypostfix_postdrop_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
postfix_postdrop:</i></p>
<p style="margin-left:11%; margin-top: 1em"><b>postfix_postdrop_exec_t</b></p>
<p style="margin-left:11%; margin-top: 1em">- Set files
with the postfix_postdrop_exec_t type, if you want to
transition an executable to the postfix_postdrop_t
domain.</p>
<p style="margin-left:11%; margin-top: 1em"><b>postfix_postdrop_t</b></p>
<p style="margin-left:11%; margin-top: 1em">- Set files
with the postfix_postdrop_t type, if you want to treat the
files as postfix postdrop data.</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>
