Spoofing is the process by which a computer is misrepresented on the network as another computer. Spoofing can be done at the hardware level (e.g. MAC address spoofing) or at the TCP/IP level (e.g. IP address spoofing). The primary purpose of spoofing is to allow the unauthorized computer to gain access to a secure network wherein the security is provided by verification of a hardware or IP address. If a Wi-Fi node is locked down to only specific pre-approved MAC addressed, for example, a malicious user seeking to gain entry would need to spoof a valid MAC address to connect to the node.
