  • Patent number: 10051004
    Abstract: An evaluation system includes a network device, a gateway device, a policy evaluation device, and first and second control devices. The network device copies a packet received from the first control device and transmits to the gateway device and the policy evaluation device. The gateway device receives the copied packet, performs a first filtering based on the policy stored in a first policy storage unit, transmits the packet to the second control device while storing the result of the first filtering, and transmits the result of the stored first filtering to the policy evaluation device. The policy evaluation device receives the copied packet, performs a second filtering based on the policy stored in a second policy storage unit, stores the result of the second filtering, and evaluates the policy stored in the second policy storage unit based on the results of the two filterings.

  • Publication number: 20170331787
    Abstract: A detection apparatus 30 stores a determination list (A1601) for determining whether there is unauthorized communication, receives a communication packet (A1501) flowing in a control system, determines whether a valid data pattern in the determination list (A1601) and a data pattern relating to the communication packet (A1501) match each other. When the valid data pattern in the determination list (A1601) and the data pattern relating to the communication packet do not match each other, the detection apparatus 30 calculates a similarity degree between the valid data pattern in the determination list and the data pattern relating to the communication packet, and determines whether the similarity degree satisfies a predetermined condition. When the similarity degree is determined not to satisfy the predetermined condition, the detection apparatus 30 determines that the communication packet (A1501) is an unauthorized communication packet.
