(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.
Since the spoofed packets appear to be sent from the targetâs IP address, all responses to the spoofed packets will be sent to (and flood) the targetâs IP address. IP spoofing attacks can also be used to bypass IP address-based authentication. This process can be very difficult and is primarily used when trust relationships are in place between machines on a network and internal systems.
