Enable the selinuxuser_ping SELinux Boolean

An XCCDF Rule

Description

By default, the SELinux boolean selinuxuser_ping is enabled. If this setting is disabled, it should be enabled as it allows confined users to use ping and traceroute which is helpful for network troubleshooting. To enable the selinuxuser_ping SELinux boolean, run the following command:

$ sudo setsebool -P selinuxuser_ping on
