starting from scratch

well... i need to protect my computer from anyone and anything that could possibly happen, i have some VERY VERY VERY important documents an things on my pc that have to be protected. I'm running a dual boot, fedora and windows xp (shudders at the thought of a microsoft product)
my pc is on a basic home network with 3 or 4 other pc's were running a basic wireless router.
what kind of software can i get for fedora or any linux os, and xp that will protect my home network from guys walking down the road with a laptop, or people tapping into the network?

That's a pretty big question there ...

Basically, Fedora comes with very good (some will say the very best) protection for what you want to do. The tools are there, as usual it is a matter of learning about them and configuring them.

Look at IPTables and SELinux for security issues.

All wireless traffic should be encrypted by default. That should just leave viruses and spyware to get rid of (like someone storing all your keypresses). There are many commercial apps to combat this. A nice one is Fisk Software's F-Prot - free for home users - which has both linux and windows versions.

XP should not connect to the internet or pass LAN traffic if you can help it.

Of course, if the files are very very important, consider using a secure machine - not connected to net or lan, so the only way info gets passed from one to the other is by swapping disks over.

Security issues are actually very simple and the basic dilemma is the old wallet problem: you want your money to be safe, so you keep it in a vault. But you want to be able to buy things, so you keep it in your wallet. The convenience is vulnerability.

Beyond that - how safe do you want? Encrypting all wireless traffic will stop most folk who just randomly cruise around with their portable whosit. A bit like having a padlock on an outside bolt. A proffessional will still be able to pick it without too much trouble - depending on how badly they want in. And there's always a crowbar. Anti spyware makes it hard to steal the key. I understand the SELinux is like adding armour plate!
