[wplug] Who benefits from SELinux?

[G.Pitman]

I use it at work for every server that I can, but we have govt. and
commercial contracts. One particular instance where it helped was a web
server where a bad php script allowed someone to upload a script to the
temp directory and try to execute it to likely get a privilege escalation.
Selinux sets contexts on files and directories specifying who can read or
write to them.
