ATTACK PACKET DETOUR SYSTEM, METHOD, AND ROUTER WITH TUNNEL FUNCTION

摘要

PROBLEM TO BE SOLVED: To correctly transfer a normal packet to a destination without generating a loop.

SOLUTION: When a normal computer 2 starts the transmission of the normal packet to a server 3 to be attacked, a router 222 with a tunnel function transfers the packet to an attack packet detecting/addressing device 201 with the use of a tunnel 212 in order to allow a destination address to match the destination address of an access control list 2005. The device 201 analyzes the packet and returns the packet since the packet is the normal one in this case. A router 231 transfers the packet to the router 222 by IP routing. Since the line and destination address of the reception packet do not match those of the access control list 2005, the router 222 transfers the packet to the router 232 in response to a routing table 2006. The router 232 transfers the packet to the server 3 to be attacked by IP routing.
