Discussion

Without verification of the security functions, security functions may not operate correctly and the failure may go unnoticed. Security function is defined as the hardware, software, and/or firmware of the information system responsible for enforcing the system security policy and supporting the isolation of code and data on which the protection is based. Security functionality includes, but is not limited to, establishing system accounts, configuring access authorizations (i.e., permissions, privileges), setting events to be audited, and setting intrusion detection parameters.

This requirement applies to operating systems performing security function verification/testing and/or systems and environments that require this functionality.

Check

Verify "SELinux" is active and enforcing the targeted policy with the following command:

     > sudo sestatus
     SELinux status: enabled
     SELinuxfs mount: /sys/fs/selinux
     SELinux root directory: /etc/selinux
     Loaded policy name: targeted
     Current mode: enforcing
     Mode from config file: enforcing
     Policy MLS status: enabled
     Policy deny_unknown status: allowed
     Memory protection checking: actual (secure)
     Max kernel policy version: 33

If the "Loaded policy name" is not set to "targeted", this is a finding.

Fix

Configure SLEM 5 to verify correct operation of all security functions.

Add or modify the following line in the "/etc/selinux/config" file:

SELINUXTYPE=targeted

A reboot is required for the changes to take effect.
