Abstract: An information processing system includes a storage unit that stores association information that is obtained by associating identifying information of a plurality of second communication networks that are interconnected via a first communication network with identifying information of a virtual device that exists in the second communication network; a first specifying unit that specifies according to the association information a second communication network in which a target virtual device exists, in a case in which the first specifying unit acquires a request for a setting change to the target virtual device; a second specifying unit that specifies a physical server on which the target virtual device runs from among physical servers that exist in the specified second communication network; and a setting unit that performs the setting change to the target virtual device that runs on the specified physical server.

Abstract: A communication control device includes a storage that stores management information in which an first address of a network interface of a first information processing device for which first communication with the communication control device has been allowed, first identification information corresponding to the first address, and first port information corresponding to a first port of the communication control device for which the first communication has been allowed are associated with one another, and a determination processor that determines whether or not to allow second communication with a second information processing device on a basis of the first identification information and a second identification information, which has been received from the second information processing device performing the second communication.
