IP Spoofing Law and Legal Definition

IP (Internet Protocol) spoofing is one of the most common forms of on-line camouflage. It is 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. To engage in IP spoofing, a hacker must find an IP address that is allowed, then modify the header information in the data packets from his or her own computer to include this IP address. Newer routers and firewall arrangements offer protection against IP spoofing.
