I did note that the debian pages on security are a bit dated.
I suppose I should lend a hand there if I can find the time. How about
you, do you have the time? You don't have to start out understanding
the whole list, you just have to be willing to look up the debian
packages, learn how their setup works, and write down what you
learned, discuss it on the appropriate lists, then write up some
summaries and submit them. If you do good work, you'll be invited to
assume responsibility for some of the wiki pages.

I suppose it's easier to get into an openbsd server than it is to fly
to the moon, but if you set up an openbsd server and keep it updated,
attackers will generally find it easier to try social engineering
instead of attacking the server directly.
Modulo the services you run, but that's true of any OS. If you are
running a hypertext protocol server and it has a hole, you have a hole
in your server.

Basically, you're supposed to buy the CDs from the project. CDs are a
bit harder to spoof than dns, and they come out every six months.

There is no operating system that is secure for people who aren't
willing to learn how to admin the thing.

That's why you don't surf the web as an admin user.
There are lots of things I left out, to avoid dropping an elephant on
the list. One is that you should avoid X11 user switching in general,
and especially when you are doing admin work..
Be careful where you see conspiracy.
Look first in your own heart.
