I think a thorough understanding of security should be required for anyone
wanting to learn Unix skills; there really isn't that much to setting up a
firewall (there are only two kinds; IP filter and application level), but
there's all kinds of stuff you can do to keep track of your system and
ensure that if it is hacked, at least you know about it. Much of the
security monitoring equipment will also tell you about the mechanics of the
system; what are the weak points, how inetd works, why the whole idea of
root isn't always a good one... that kind of thing. I'm still learning
myself, but it's a good confidence building activity.
