I do that, so I'm secure (Loooong, mixed character password on WEP);
Now that I am secure, I can't let anyone else 'share' my public files or my internet connection without giving them access to my personal files and helping them hack my system..(As I understand it anyway.)
I have OSX and a wireless AP -BTW. So if I turn off WEP people can log onto my network, but they would still have to log in as a User or Administrator to check out my desktop/system. As I'm running multi-user, my system should be as safe as the User's password, right? I've heard passwords can be broken, but I really have a hard time believing anyone would invest that much trouble with my little network.
-Sorry it's so long.-^- I guess I'm asking: "How much of a security risk is a 'Wardriver' with access to the Network if said 'Wardriver' has no login priveleges? And if they have no login priveleges, can they share the connection?" (Assuming I enabled the proper prefences.) As you can tell, I have no fucking idea...
BTW-As it is, my laptop shares the connection via the AP, and a login is still required to access my desktop machine via the network.
