A good firewall will defeat anything except a massive distributed DOS attack. Setting that up would require launching a trojan to infect unsuspecting internet users.
A Good Firewall is only an inconvenience. I have a public IP, and one night, I was up at 2 AM (I am a Programmer who was a Hacker long enough ago that the statutes have expired
) and my public Network lights up with activity that I am not causing, so I log on to the Server, some guy has gotten through the hardware firewall (not hard) and is port scanning my server, I fire up some software I have, back trace his IP through a couple of remote controlled computers, and find out his IP is from the old Soviet block. I started a scan of his home IP, and he shut down his computer faster than you can say OOPS!!! (then I blocked all the IP Addresses belonging to his ISP)
The point is, if these guys want to get caught, just attack where people will be watching
(Thats a Dare, go on Attack the GOP during their Convention, and you WILL be caught), So come on guys (and gals) show how sneaky you are attack a big heavily watched site, make a name for your selves, and help us get you off the (net) streets.
I was a smart Hacker, if there is such a thing, because: 1) I never damaged anything 2) I never bragged about where Id been, and 3) I decided on my own it was not a fun game without having to be caught.
Cheers
