Enable the fips_mode SELinux Boolean

An XCCDF Rule

Description

By default, the SELinux boolean fips_mode is enabled. This allows all SELinux domains to execute in fips_mode. If this setting is disabled, it should be enabled. To enable the fips_mode SELinux boolean, run the following command:

$ sudo setsebool -P fips_mode on
