Hello Folks

I've been sneaking around on ao for some time. Mostly to download stuff, though I peeked in the forums once in a while. About time I make some constructive posts.

My interest in computer security springs from the following:

I work as a programmer at a financial newspaper in Denmark. My primary task is writing php/mysql code for the main site borsen.dk.
My secondary task concerns server maintainance and server security. All our servers, except one, run debian linux. In this environment I work with C++ code. For firewalling we use the standard ipchains.

So my main purpose in coming here is to learn about linux security. I've already annoyed my colleagues in other (more windoze oriented) departments by demonstrating weaknesses in MS servers of different kind. But linux is quite another thing to compromise
