    Abstract: This security device comprises: a plurality of communication ports that can be connected to apparatuses; a switch unit that is able to communicate with a plurality of the apparatuses through the plurality of communication ports; and an authentication unit that acquires a connection command for at least any one of the apparatuses among the plurality of apparatuses, the connection command including authentication information, and that authenticates the connection command on the basis of the authentication information. When the authentication is successful, the authentication unit sets a communicable range, which is formed by the switch unit, of the at least any one of the apparatuses through the switch unit, in accordance with the connection command.

    Abstract: A security system includes an information transmission device, and a security device to which a target device is connectable. The information transmission device and the security device are connected to each other via a network. The information transmission device transmits, to the security device, generation information to be used for generating reference identification information. The security device generates the reference identification information by using the generation information received from the information transmission device via the network. The security device acquires identification information of the target device connected to the security device. The security device compares the acquired identification information with the generated reference identification information, and determines validity of the target device connected thereto, based on a result of comparison.

    IPC: H04L43/08

    Abstract: A detection device includes: a switch provided to a transmission path that connects a plurality of function units to each other; a measurement unit configured to measure a signal that passes the transmission path, at a first node on a first end side of the switch and at a second node on a second end side of the switch; and a detection unit configured to compare a measurement result at the first node and a measurement result at the second node, which are obtained by the measurement unit, with a reference measurement result which is a measurement result for reference, and detect abnormality regarding the transmission path, based on a result of the comparison.
