I think that article is mostly FUD (note that its sponsored by MS) but
your question is still a good one. There are many articles on how to
secure a linux box. Start with apt-get'ing harden-doc. 

To determine that a system is not compromised, you have to start with
a system that's not compromised. Once you get that (try a live-cd as a
way to examine a previously installed system) go for packages like
tiger and tripwire. Read up on them, learn them and then use them
