Description
Spoofing source addresses occurs when a malicious user outside the network has created packets with source address belonging to the private address space of the target network. This is done in an attempt to slip through perimeter as a member host to gain access to internal resources or to conceal identity to perform an attack. It is imperative that all inbound and outbound traffic with spoofed or invalid source addresses are blocked.
