The firewall, which uses routers supplied by Cisco, works in part by inspecting Web traffic for certain keywords that the Chinese government wishes to censor, including political ideologies and groups it finds unacceptable.
The Cambridge research group tested the firewall by firing data packets containing the word “Falun” at it, a reference to the Falun Gong religious group, which is banned in China.
The researchers found that it was possible to circumvent the Chinese intrusion detection systems by ignoring the forged transmission control protocol resets injected by the Chinese routers, which would normally force the endpoints to abandon the connection.
