Zone based firewalls

I am new to the world of firewalls... and going over the ZBFWs. I am not sure what is the motive for creating such a FW, I see am example where the INSIDE and outside are grouped as int zones and the traffic is inspected with policy maps, all within a router. Well, all this could be done with prev int based ACL rules. What is something that is pushing for the need to have ZBFWs.

thanks,

I've not used ZBFWs in a production environment, but "supposedly" a ZBF is more robust than simply controlling access.

It allows you to inspect traffic and block any traffic with potentially malicious code. By creating the zones, you can set additional rules based on your group/zones

Good logic, but everything is still within a router, how does it prevent any attacks...
