An analysis unitgenerates one or more pairs of a start point fact which is a fact representing possibility of the attack in a device that is a start point and an end point fact which is a fact representing possibility of the attack in the device that is an end point, analyzes, for each pair, whether or not it is possible to derive the end point fact from the start point fact, based on facts representing states of the devices generated based on information regarding the device that is the start point and information regarding the device that is the end point, the start point fact, and one or more analysis rules for analyzing the attack, and generates an attack scenario in a case where it is possible to derive the end point fact from the start point fact.

Analysis system, method, and program

A management apparatus, a management method, and a storage medium that can appropriately deny an application intended not to change a software configuration of a device are provided. The management apparatus includes: an acceptance unit that accepts, from an applicant, an application intended not to change a software configuration of a device; and a processing unit that denies the application based on the number of times of applications accepted by the acceptance unit.

Management apparatus, management method, and storage medium

An image monitoring system is provided with: a region forecast acquiring unit () for acquiring a region forecast which is predictive information about a predetermined item designated as a factor causing a change in a capture environment that is the environment of a capture region, wherein the predictive information serves as predictive information about the predetermined item at a future time in a predetermined region including the capture region where an image to be image-analyzed is captured; a change index specifying unit () for specifying, based on the acquired region forecast, a change index including at least a change timeslot that is a timeslot during which the change in the capture environment is brought about; and a detection sensitivity setting unit () for altering, based on the specified change index, a setup parameter that is a parameter for detecting an abnormality in the image analysis.

Image monitoring system, image monitoring method, and image monitoring program

Provided are a communications state determination device, etc., capable of improving the accuracy of network state specification. This communications state estimation device comprises: a setting means that, in accordance with given communications parameters, applies the communications parameters to a communications device that determines the occurrence of communications errors in communications with a communications destination device; a detection means that sends communications instructions to the communications device that performs communications, in accordance with received communications instructions, and detects the occurrence of communications errors that have been determined in the communications that are in accordance with the instructions; and an estimation means that estimates whether or not the communications device can perform the communications, on the basis of the communications parameters and the existence or otherwise of communications errors.

Communications state estimation device, communications state estimation method, and storage medium that stores communications state estimation program

A node device has a delivery predictability management part, a DTN communication part, and a user interface part. The delivery predictability management part stores, for each destination node, delivery predictabilities including a delivery predictability for the destination node calculated by a local node and a delivery predictability for the destination node calculated by a neighboring node. The DTN communication part refers to the delivery predictabilities for each destination node and selects a next hop node in transferring transfer data from the local node to the destination node. The user interface part allows selection of a destination node for DTN communication with the local node as a source node on a basis of the delivery predictabilities for each destination node.

Delay tolerant network (DTN) and ad-hoc node device

A data-storing-terminal counting unit counts the number of communication terminals in which each of a number of data are stored. Based on the results of the counts, a communication terminal count estimation unit estimates the number of communication terminals that will transmit data with the same timing. An adjustment reference value calculation unit computes an adjustment reference value for constraining the number of communication terminals estimated by the communication terminal count estimation unit to be less than or equal to a preset allowable number. On the basis of the adjustment reference value computed by the adjustment reference value calculation unit, a determination unit determines whether or not to permit transmission of data stored by a storing means. If the determination unit permits the transmission of said data, a data transmission unit transmits the data to a communication terminal in which said data is not stored.

Communication terminal, communication method, storage medium on which communication program is stored, and communication system

A selected node of a network of nodes determines a communication path through the network, by iteratively performing the following until a pipe diameter value (PDV) converges. An approximate pressure value (APV) of the selected node is determined by repeatingly acquiring an adjacent node's provisional pressure value (PPV), and updating a PPV of the selected node based on the PDV and a length of each of a number of links, the adjacent node's PPV, and the selected node's flux. After the selected node's APV is determined, an APV of the adjacent node is acquired, and a flux of each link is determined based on the PDV, the link's length, and the adjacent and selected nodes' APVs. The PDV is updated based on each link's flux that has been determined, the PDV, and a slime mold function, without acquiring and without using any PDV of the adjacent node.
