I have several computers that the SDSC is kind enough to allow me to place directly
on the Internet. One of the policies they have is that if a system is broken
into,
it will be confiscated for investigation. In order to keep this from occurring,
I researched how to secure them. Since there were multiple systems (same operating
system), I documented what I had done, so that I could do it again. Tom Perrine,
SDSC's senior computer security expert at that time, saw what I had done, and
suggested
that
I give a presentation on it.
Instead of a presentation, I decided to create a paper. This web page is that
paper.
