mod_security rules for my server

there're (basically) two kinds of attacks:
- remote attacks
- local attacks

you won't have problems with local attack, but may have problems with remote attacks

if you don't secure your box my guess is that, if you get hacked, that's because a local+remote attack...
something like:
someone finds a vulnerability on vBulletin (or someother program your using) and get access to run commands as it's username... then using this privilege he makes a "local" attack
