The best way to counter-act security vunerabilities is to watch the people using them. Monitor their little hacking communities & learn what they know, in order to protect yourself.
It's quite simple to infiltrate their community, just make yourself a geek name like "nitr0" or "bl1ng", start posting on their message boards & chatting in their chats.
Your learn more in one night in security like that, then you could in 10 years reading manuals & installing patch's.
Of course you could always hire a security "pro" to handle your problems
