A communication control method which performs route control in a communication system comprising: a specific network constituting the Internet; a first network configured to accommodate a specific device connected to the specific network; a second network provided between the specific network and the first network; and a processing device configured to perform predetermined processing on the basis of a packet transmitted between the specific network and the first network, the communication control method comprising: causing a path setting device in the communication system to execute a communication route-setting process comprised of, in accordance with first routing information defining a path leading from the first network to the specific network to be branched in the second network, controlling a path so that a first path of the branched path is set as a path via the processing device, and a second path of the branched path is set as a path leading to the specific network.

Communication control method, communication control device, and computer program

A communication controller performs route control in a communication system comprising a specific network, a first network configured to accommodate a specific device connected to the specific network, a second network provided between the specific network and the first network, and a filter configured to restrict communication according to a predetermined condition. The communication controller device includes: a route-setting device which controls the path such that a first path of the branched path is set as a path leading to a predetermined address space including an address of the specific device via the filter, and a second path of the branched path is set as a path leading to the first network in which the predetermined address space is excluded from an address space of the first network.

Communication path control method, communication path control device, and communication path control program that divide a path leading to a network that accommodates a specific device into a path that passes through a filter device and a path that does not pass through a filter device

A mitigation system comprises a plurality of types of mitigation devices which execute a defense function against an attack, and a control device which selects, if it is detected that an attack has been performed on a network to be monitored, one of the plurality of types of mitigation devices, which executes a defense function in accordance with the type of the attack.
