(Ä«-pÄ spoofÂ´ing) (n.) A technique used to gain unauthorized access to computers, whereby the intruder sends messages to a computer with an IP address indicating that the message is coming from a trusted host.
The term spoofing is generally regarded as slang, but refers to the act of fooling -- that is, presenting a false truth in a credible way. There are several different types of spoofing that occur, but most relevant to networking is the IP spoof. Most types of spoofing have a common theme: a nefarious user transmits packets with an IP address, indicating that the packets are originating from another trusted machine. The first step in spoofing is determining the IP address of a host the intended target trusts.
