Allowing source routed network traffic allows attackers to obscure their identity and location.
IP source routing is a mechanism that allows the sender to determine the IP route that a datagram should follow through the network.
Source routing allows a computer that sends a packet to specify the route that the packet takes. Attackers can use source routed packets to obscure their identity and location.
Configure the DisableIPSourceRouting entry to a value of 2.
If you configure this value to 2, all incoming source routed packets are dropped.
