The short of it is, you can set it up on your system if you really want to, but you should probably take a few minutes to RTM to realize what you’re getting yourself into.
SELinux can confine Linux users. A number of confined SELinux users exist in SELinux policy. Linux users can be mapped to confined SELinux users to take advantage of the security rules and mechanisms applied to them. For example, mapping a Linux user to the SELinux
user_uuser, results in a Linux user that is not able to run (unless configured otherwise) set user ID (setuid) applications, such assudoandsu, as well as preventing them from executing files and applications in their home directory. If configured, this prevents users from executing malicious files from their home directories.
