An onboard computer () to which data is input from outside a vehicle via a communication interface (), the onboard computer () comprising: a risk evaluation unit () configured to evaluate, based on data information of the input data, a risk when an abnormality occurs due to the data; a security strength adjustment unit () configured to adjust a security strength for the data based on the risk evaluated by the risk evaluation unit (); and a security setting unit () configured to set security for the data with the security strength adjusted by the security strength adjustment unit ().

Onboard computer, computer program, computer-readable recording medium, and security setting method

A network apparatus includes: a plurality of network interfaces; a first communication unit configured to communicate with an input and output apparatus in a first network with which a first network interface of the plurality of network interfaces is coupled; a second communication unit configured to communicate with a first device in a second network with which a second network interface of the plurality of network interfaces is coupled; and a third communication unit configured to communicate with a second device in a third network with which a third network interface of the plurality of network interfaces is coupled. When the second communication unit receives data from the second network, the data is transmitted to the first network through the first communication unit without being transmitted to the third network. When the third communication unit receives data from the third network, the data is transmitted to the first network through the first communication unit without being transmitted to the second network.

Network apparatus, input and output apparatus, and program

A communication control apparatus for controlling communication between at least one communication apparatus and a network apparatus residing on one network among a plurality of networks includes multiple communication controllers respectively provided for the plurality of networks. Each communication controller includes a memory that stores operation determination information to be used for determining processing to be performed on transmission-and-reception information, the transmission-and-reception information to be transmitted or received by the communication controller with respect to other communication controller or the network apparatus on the network and circuitry that acquires the operation determination information in response to receiving the transmission-and-reception information, and performs operation corresponding to the acquired operation determination information on the transmission-and-reception information. Each of the multiple communication controllers controls communication between the communication apparatus and the network apparatus residing on the network by performing the operation corresponding to the acquired operation determination information.

Network communication system, communication control apparatus, and recording medium

An information processing system transmits, via a first network, connection information for a second network that is different from the first network to a plurality of terminal apparatuses; carries out communications with the terminal apparatuses via the second network based on the transmitted connection information; stores respective items of terminal identification information for the terminal apparatuses, with which the communications are carried out via the second network; determines whether the terminal apparatuses that are identified by the stored items of terminal identification information can carry out communications via the second network; and, when determining that the terminal apparatuses cannot carry out communications via the second network, carries out such control as to prevent the second network from being used to carry out communications.

Information processing system and information processing method

An image forming apparatus includes a UI application that configures functions supported in an energy saving mode and in a normal mode, an energy saving memory control service that manages settings of the configured functions supported in the energy saving mode, and a filtering service that filters external access to the image forming apparatus in the energy saving mode along with the settings. In the energy saving mode, the filtering service determines whether the image forming apparatus remains in the energy saving mode or returns to the normal mode in order to process the access using the settings.
