I'm on the site because I like the community and am a texture modder.
It's called Punkbuster.
The last time I checked, Nexon won't use Punkbuster because they would rather rely on their Black Cipher hackshield and it's too "complicated" for them to incorporate it into Combat Arms. But who knows, maybe they will change their minds.
I don't know about permanent anti-hack, the CA hacks section would become kinda pointless :P Maybe they could do something like if you knife like 4 people in 1 sec they auto kick you, and if you do it again, you are at the mercy of some moderator? No the Elite Moderators, they are just shit. They will kick anyone who even dares to headshot them on pointblank range. I once spawned, and a super elite moderator emptied his kriss mag on me, I headshot him in a reflex swing, and he reported me ^_^
