In networking, spoofing involves the deceptive manipulation of network communication to disguise the true origin or identity of a sender. A common form of this practice is IP address spoofing, where attackers forge the source address in network packets to appear as if they are coming from a trusted source. This deceitful technique is often exploited for malicious purposes, such as bypassing access controls or launching DoS attacks. By falsifying the source IP address, attackers can deceive recipients into trusting the legitimacy of the communication. To counteract spoofing, security measures like ingress and egress filtering are implemented, along with the use of cryptographic protocols and anti-spoofing techniques, to enhance the integrity and authenticity of network communication.
