<h1>Switching to Targeted Reference Policy</h1>
|
|
<p>
|
|
The targeted policy is now available on Fedora Core 5 systems, as selinux-policy-targeted 2.*.
|
|
If you are using Rawhide, simply update your policy using yum.
|
|
This guide will walk you through switching to the targeted reference
|
|
policy on a Fedora system not using these repositories.
|
|
<p>
|
|
<h2>
|
|
Download and unpack the policy
|
|
</h2>
|
|
<p>
|
|
The policy is <a href="index.php?page=download">available</a>
|
|
from Sourceforge. Download the policy, and unpack it to a temporary
|
|
directory. Then use the install-src make target to install the policy
|
|
sources.
|
|
</p>
|
|
<div id="codeblock">
|
|
<pre>
|
|
# <b>tar -jxvf refpolicy-20050922.tar.bz2 -C /tmp</b>
|
|
# <b>cd /tmp/refpolicy</b>
|
|
# <b>make install-src</b>
|
|
</pre>
|
|
</div>
|
|
<h2>
|
|
Configure the policy
|
|
</h2>
|
|
<p>
|
|
The policy source is found in the
|
|
/etc/selinux/refpolicy/src/policy/ directory.
|
|
</p>
|
|
<div id="codeblock">
|
|
<pre>
|
|
# <b>cd /etc/selinux/refpolicy/src/policy</b>
|
|
</pre>
|
|
</div>
|
|
<p>
|
|
Edit the policy Makefile (/etc/selinux/refpolicy/src/policy/Makefile).
|
|
Near the top of the file, the policy has a few build options.
|
|
The TYPE needs to be set to targeted, the DISTRO option needs to be
|
|
uncommented and set to redhat, and DIRECT_INITRC should be set to y.
|
|

Install the policy

</h2>
|

<p>
|
|
Next, install the policy, application configuration files, and
|
|
file contexts.

</p>
|

<div id="codeblock">

<h2>
|
|
Change SELinux Configuration
|
|
</h2>
|
|
<p>
|
|
Modify the /etc/selinux/config file, and set SELINUXTYPE to refpolicy.
|
|
It should look similar to this:
|
|
</p>
|
|
<div id="codeblock">
|
|
<pre>
|
|
# This file controls the state of SELinux on the system.
|
|
# SELINUX= can take one of these three values:
|
|
# enforcing - SELinux security policy is enforced.
|
|
# permissive - SELinux prints warnings instead of enforcing.
|
|
# disabled - No SELinux policy is loaded.
|
|
SELINUX=enforcing
|
|
# SELINUXTYPE= can take one of these two values:
|
|
# targeted - Only targeted network daemons are protected.
|
|
# strict - Full SELinux protection.

</div>

<h2>
|
|
Restart and Relabel
|
|
</h2>
|
|
<p>
|
|
The system needs to be restarted with the new policy, and relabeled
|
|
on booting, to finalize the switch.
