How Is Ip Address Spoofing Detected?

Detecting IP spoofing can be difficult because it works by modifying the headers of IP packets. Network administrators can use a variety of techniques to detect IP spoofing such as Reverse Path Filtering, Source Address Validation, and Packet Filtering. Reverse Path Filtering checks if the source address of an incoming packet is valid for its outgoing interface. Source Address Validation checks the source address of an incoming packet against a whitelist or blacklist of valid source addresses. Finally, Packet Filtering inspects packets for suspicious source or destination addresses and flags those that do not match the criteria.
