    Abstract: A device includes: an input/output unit configured to receive input of the binary of the software to be monitored in which a tamper detection feature and tamper detection feature calling functions are embedded; a CFG generation unit configured to generate a CFG based on the binary; and an allowed list creation unit configured to determine the monitoring range for the tamper detection feature calling functions based on the CFG. The allowed list creation unit sequentially selects the tamper detection feature calling functions on the CFG, adds a node to the monitoring range for the selected tamper detection feature calling functions according to a predetermined rule, searches for the tamper detection feature calling function that may be executed next to the added node according to the predetermined rule, and adds the found tamper detection feature calling function to the monitoring range for the selected tamper detection feature calling functions.

    Abstract: When some failure occurs in the case where power interchange is performed among grids, an alternate route is searched at high speed in consideration of a deficiency/excess amount of power. A power network system has a plurality of power routers (1-7), power transmission lines (100-111) connecting the power routers, a controller (8), a communication network (10), and communication lines (11). The controller (8) obtains a reception electric energy and a transmission electric energy in the power routers (1-7), detects a failure due to a fault in, for example, the power router (4), and searches for an alternate route to solve deficiency/excess power caused by the failure occurrence. Concretely, an alternate route is searched while following a power router having excessive power as a root node by a breadth first search, and transmitting the deficiency/excess power and an allowable power transmission capacity in each of the power routers to an adjacent power router. A control instruction related to interchange power is output via the alternate route.

    Abstract: Provided is an analysis system that allows a security administrator to understand the impact of known vulnerabilities on the system to be diagnosed. The topology identification unit 14 identifies network topology of devices included in a system to be diagnosed. The analysis unit 6 generates an attack pattern that includes an attack condition, an attack result, an attack means that is vulnerability that is used by an attack, and a segment where the attack can occur in the system to be diagnosed. The display control unit 8 displays segments included in attack patterns superimposed on the network topology, on a display device. At this time, the display control unit 8 changes a display mode of the segment according to a type of the vulnerability that corresponds to the attack means included in the attack pattern including the segment.

    Abstract: A video collection system includes: a plurality of terminals; and a video collection server that requests at least one of the plurality of terminals to perform information provision. The video collection server includes a calculation part, a determination part, and a request part. The calculation part calculates, based on information acquired from a camera(s), a first area(s) imaged by the camera(s). The determination part determines a second area(s) as an information provision target(s) based on a location(s) of the first area(s). The request part selects, based on respective locations of the plurality of terminals and a location(s) of the second area(s), a terminal(s) to be requested to perform the information provision from the plurality of terminals and requests the selected terminal(s) to provide video data of the second area(s).
