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

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



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

<p style="margin-left:11%; margin-top: 1em">The
httpd_user_script processes execute with the
httpd_user_script_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 httpd_user_script_t</b></p>

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


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

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


<p style="margin-left:11%; margin-top: 1em">/home/[^/]+/((www)|(web)|(public_html))/cgi-bin(/.+)?</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
httpd_user_script policy is very flexible allowing users to
setup their httpd_user_script processes in as secure a
method as possible.</p>

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


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

<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a httpd_user_script_t</b> can be
used to make the process type httpd_user_script_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.
httpd_user_script policy is extremely flexible and has
several booleans that allow you to manipulate the policy and
run httpd_user_script 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 httpd cgi support, you must turn on the
httpd_enable_cgi boolean. Enabled by default.</p>

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

<p style="margin-left:11%; margin-top: 1em">If you want to
allow httpd to read home directories, you must turn on the
httpd_enable_homedirs boolean. Disabled by default.</p>

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

<p style="margin-left:11%; margin-top: 1em">If you want to
allow httpd to read user content, you must turn on the
httpd_read_user_content boolean. Disabled by default.</p>

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

<p style="margin-left:11%; margin-top: 1em">If you want to
unify HTTPD handling of all content files, you must turn on
the httpd_unified boolean. Disabled by default.</p>

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


<p style="margin-left:11%; margin-top: 1em"><b>krb5_host_rcache_t</b></p>


<p style="margin-left:11%; margin-top: 1em">/var/tmp/krb5_0.rcache2
<br>
/var/cache/krb5rcache(/.*)? <br>
/var/tmp/nfs_0 <br>
/var/tmp/DNS_25 <br>
/var/tmp/host_0 <br>
/var/tmp/imap_0 <br>

/var/tmp/ldapmap1_0</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>&minus;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
httpd_user_script policy is very flexible allowing users to
setup their httpd_user_script processes in as secure a
method as possible.</p>

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


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

<p style="margin-left:11%; margin-top: 1em">- Set files
with the httpd_user_script_exec_t type, if you want to
transition an executable to the httpd_user_script_t
domain.</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>
