Stuart Jansen, instructor, author and chief bottle washer at Guru Labs, will
be presenting An Introduction to SELinux.

The traditional Unix security model is simple and beautiful. For decades it
has been good enough for most people. However, it is starting to show its age.
In the highest security settings, a more fine grained control system is
needed. In the past, this meant using expensive, complicated, special purpose
versions of Unix: trusted systems. (Trusted Solaris, Trusted AIX, Trusted
HP-UX)

SELinux, created by the NSA, is the most mature and complete response to the
need for Trusted Linux systems. Unfortunately, because of the difficulty
creating and maintaining trusted systems, their success has been limited. This
is no longer acceptable.

Today, even desktop systems and cell phones need high quality security.
Imagine being able to sandbox your Web browser and e-mail client. The
traditional Unix model makes this difficult and only partially possible.
SELinux, on the other hand, makes fine grained security available to everyone.

When it first appeared, SELinux was hard to learn and mysterious to
troubleshoot. As a result, many people fear it. However, SELinux and the tools
to manage it have come a long way. It's time to lay fear aside. Stuart will
teach what SELinux is, why it is great, basic troubleshooting and maintenance.
