Discussion

Setting the SELinux policy to "targeted" or a more specialized policy ensures the system will confine processes that are likely to be targeted for exploitation, such as network or system services. Note: During the development or debugging of SELinux modules, it is common to temporarily place nonproduction systems in "permissive" mode. In such temporary cases, SELinux policies should be developed, and once work is completed, the system should be reconfigured to "targeted".

Check Content

Verify the SELinux on AlmaLinux OS 9 is using the targeted policy with the following command:

$ sestatus | grep policy

Loaded policy name:             targeted

If the loaded policy name is not "targeted", this is a finding.

Fix Text

Configure AlmaLinux OS 9 to use the targeted SELINUX policy.

Edit the file "/etc/selinux/config" and add or modify the following line:

 SELINUXTYPE=targeted 

A reboot is required for the changes to take effect.
