If a new exploit is known to impact Apache Web servers, what type of port

scan should an administrator use to identify potentially vulnerable servers

on his network?

Using a transport layer sequence prediction tool such as Nmap, evaluate a

variety of network devices. In addition to operating systems such as Windows, Linux, and BSD, evaluate network routers, firewalls, VoIP, and

hand-held devices. Which devices have the most random sequence generators? Is there a reason why some classes of devices are more predictable?
