Study questions for network security:

1. what is a buffer overflow attack?  why can't we stop them?
	what measures if any exist to stop them?

2. describe (characterize) the following attacks:

	winnuke

	teardrop

	land

	ILOVEYOU

	smurf

	DDOS (at least the tribal flood variant)

	ping of death

	cgi-bin phonebook script attack

3. describe how the following firewall mechanisms can "deal with"
	(or cannot deal with) the above attacks

	plain old router-based packet filter

	application proxy (one smart server/process per
		application protocol that *understands* the protocol)

	circuit-proxy (doesn't understand the protocol)

4. contrast the impact on a per attack-basis (attacks in 2) between
	trying to use a 
		deny all, accept a few policy 
	vs. a 
		access all, deny a few (bad things) 
	policy assuming your only firewall tool is a Cisco router.

5. any attacks we did NOT deal with.  How for example, could
	the ILOVEYOU attack have been dealt with by the manufacturer
	of the software?
