Chapter 5. The sepolicy Suite
Chapter 5. The sepolicy Suite The sepolicy utility provides a suite of features to query the installed SELinux policy. These features are either new or were previously provided by separate utilities, such as sepolgen or setrans . The suite allows you to generate transition reports, man pages, or even new policy modules, thus giving users easier access and better understanding of the SELinux policy. The policycoreutils-devel package provides sepolicy . Enter the following command as the root user to install sepolicy : The sepolicy suite provides the following features that are invoked as command-line parameters: Table 5.1.

The sepolicy Python Bindings In versions of Red Hat Enterprise Linux, the setools package included the sesearch and seinfo utilities. The sesearch utility is used for searching rules in a SELinux policy while the seinfo utility allows you to query various other components in the policy. In Red Hat Enterprise Linux 7, Python bindings for sesearch and seinfo have been added so that you can use the functionality of these utilities through the sepolicy suite. See the example below:
~]# yum install policycoreutils-devel > python >>> import sepolicy >>> sepolicy.info(sepolicy.ATTRIBUTE) Returns a dictionary of all information about SELinux Attributes >>>sepolicy.search([sepolicy.ALLOW]) Returns a dictionary of all allow rules in the policy.
