Internet Protocol Security. A developing standard for security at the network or packet processing layer of network communication.

A signal that informs the OS that something has occurred.

A security management system for computers and networks. An IDS gathers and analyzes information from various areas within a computer or a network to identify possible security breaches, which include both intrusions (attacks from outside the organization) and misuse (attacks from within the organization).

IP	Internet Protocol. The method or protocol by which data is sent from one computer to another on the
	Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely
	identifies it from all other computers on the Internet.
IP address	A computer's inter-network address that is assigned for use by the Internet Protocol and other
	protocols. An IP version 4 address is written as a series of four 8-bit numbers separated by periods.
IP flood	A denial of service attack that sends a host more echo request ("ping") packets than the protocol
	implementation can handle.
IP forwarding	An Operating System option that allows a host to act as a router. A system that has more than 1
	network interface card must have IP forwarding turned on in order for the system to be able to act as
	a router.
IP poofing	The technique of supplying a false IP address.
