"Z" is your friend...

When I took over maintenance of the SELinux userspace I settled on to using "Z" as the universal option to show security context.

So "ps auxZ" will show you the security context of all processes. "ls -Z" will show you the security context of files. "id -Z" will show you the security context of your login shell.

So if you think an application might be SELinux aware try the -Z option...
