What is one technique that can reduce attack vectors from IP, TCP, and

UDP?

Collect a set of network devices, such as home firewalls, network-enabled

phones, PDAs, palmtops, and music players. Use nmap to scan for open

network services, and ethereal (or similar analysis tool) to evaluate TCP

packets. Do the devices have unique TCP profiles? How do the devices respond to invalid TCP checksums or LAND attacks?
