Antispoofing

Primary definition

Antispoofing refers to techniques, technologies, and policies designed to detect and prevent attackers from masquerading as trusted entities to steal data, bypass security, or gain unauthorized access. In a spoofing attack, the source address of an incoming packet is changed to make it appear as if it is coming from a known, trusted source. Spoofed packets are commonly used to carry out denial-of-service (DoS) attacks, exploit network and system vulnerabilities, and gain unauthorized access to corporate networks and data.
