security
 

I have a website. I have vBulletin on it. This site, h4ckinab0x has a website. And I accidently did a \ at the end. And it now blocked me.
So basically, it knew I was trying to bypass their security.
How do you get it like that? So LiteSpeed will know if someone is getting in?

I want someone to explain me some security information. I want to be able to top DoS so fast.

IF anyone can get me some tutorials on security.
Thnks
