Zoom Zoom V3 IP Spoof, Checking, Ping of Death, Land Attack, Reassembly, Synchronize, Flooding

IP Spoof	Inspects so-called “trusted” IP addresses to ensure
checking	legitimacy.
Ping of Death	Prevents oversized ping packet fragments (totaling
checking	more than 65,536 bytes) from getting through—
	which cause the computer to hang or crash.
Land Attack	Guards against attackers who mimic source and
checking	destination ports and IP addresses, causing infinite
	loops and system crashes.
Reassembly	Ensures correct reassembly of datagrams—
checking	prevents attackers from sending a continuous
	stream of identical, invalid datagram fragments that
	can cause system state problems.
SYN	Prevents attackers from flooding the system with
(synchronize)	incomplete synchronization connection requests,
Flooding	which can exhaust server resources and cause
checking	operating system crashes.
ICMP	Keeps route information hidden, ensuring that ICMP
Redirection	messages cannot be compromised, or forged, and
checking	redirected to the attacker’s destination of choice.
Source	Prevents attackers from illegally obtaining network
Routing	data by stipulating that data packets must follow
checking	strict source routing.
Winnuke	Only applicable to Windows 95, NT, and 3.11
checking	systems. Prevents OOB (out of band) data from
	reaching an IP address, which can cause lost
	connections and system crashes.
