- The process of deception by which an unauthorized person causes a transmission or message to appear to come from an authorized user in order to gain privileged access to computer or network resources.

- The process of deception by which a system alters its identity or creates additional identities, to impersonate another device in a communications session or transaction. Spoofing may be desirable, as when a router spoofs a fax protocol to ensure delivery over a connection with high latency. See also fax spoofing.
The cyberspace appropriation of an authentic user’s identity by nonauthentic users, causing fraud or attempted fraud, in some cases, and causing critical infrastructure breakdowns in other cases. Spoofing can also target nonuser-based entities. For instance, an IP address can be spoofed to appropriate the identity of a server and not a human (user).
