<h2>NAME
<a name="NAME"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">netutils_selinux
− Security Enhanced Linux Policy for the netutils
processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the netutils processes via flexible mandatory
access control.</p>
<p style="margin-left:11%; margin-top: 1em">The netutils
processes execute with the netutils_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 netutils_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The netutils_t
SELinux type can be entered via the <b>netutils_exec_t</b>
file type.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the netutils_t domain are the
following:</p>
<p style="margin-left:11%; margin-top: 1em">/bin/arping,
/sbin/arping, /usr/bin/arping, /usr/sbin/arping,
/usr/sbin/tcpdump</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
netutils policy is very flexible allowing users to setup
their netutils processes in as secure a method as
possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for netutils:</p>
<p style="margin-left:11%; margin-top: 1em"><b>netutils_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a netutils_t</b> can be used to make
the process type netutils_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. netutils
policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run netutils with the
tightest access possible.</p>
<p style="margin-left:11%; margin-top: 1em">If you want to
deny all system processes and Linux users to use bluetooth
wireless technology, you must turn on the deny_bluetooth
boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
deny_bluetooth 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>MANAGED FILES
<a name="MANAGED FILES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The SELinux
process type netutils_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>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/DNS_25 <br>
/var/tmp/host_0 <br>
/var/tmp/imap_0 <br>
/var/tmp/HTTP_23 <br>
/var/tmp/HTTP_48 <br>
/var/tmp/ldap_55 <br>
/var/tmp/ldap_487 <br>
/var/tmp/ldapmap1_0</p>
<p style="margin-left:11%; margin-top: 1em"><b>netutils_tmp_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
netutils policy is very flexible allowing users to setup
their netutils 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 netutils, 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 netutils_tmp_t
’/srv/mynetutils_content(/.*)?’ <br>
restorecon -R -v /srv/mynetutils_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 netutils:</i></p>
<p style="margin-left:11%; margin-top: 1em"><b>netutils_exec_t</b></p>
<p style="margin-left:11%; margin-top: 1em">- Set files
with the netutils_exec_t type, if you want to transition an
executable to the netutils_t domain. <br>
Paths:</p>
<p style="margin-left:18%;">/bin/arping, /sbin/arping,
/usr/bin/arping, /usr/sbin/arping, /usr/sbin/tcpdump</p>
<p style="margin-left:11%; margin-top: 1em"><b>netutils_tmp_t</b></p>
<p style="margin-left:11%; margin-top: 1em">- Set files
with the netutils_tmp_t type, if you want to store netutils
temporary files in the /tmp directories.</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>
