摘要： A computer system comprises an analysis module configured to execute dynamic analysis for a sample of a malicious program, and to output an analysis result including a coupling destination to and from which the malicious program communicates; a variation detection module configured to detect variation of the coupling destination based on results of cyclic observation of the coupling destination, and to output a result of the detection; and an information sharing module configured to store information output from the analysis module and information output from the variation detection module in a form that allows sharing among a plurality of external computers.

摘要： A response support technology for minimizing the impact on jobs as much as possible and enabling job continuity and prompt response can be realized. A response support device that supports a response executed according to a situation of an incident that has occurred in a monitoring target, includes an incident evaluation unit 103 that evaluates an impact of the incident on the monitoring target and an urgency level of the response against the incident; a response evaluation unit 104 that evaluates an impact level on jobs and an effectiveness level to the incident, for the response against the incident; a priority order determination unit 105 that determines a priority order of responses based on evaluation by the incident evaluation unit and evaluation by the response evaluation unit; and a display unit 106 that displays a screen including the priority order of responses determined by the priority order determination unit.

摘要： A program analysis system that analyzes a program while adjusting time elapse velocity in program execution environment sets analysis conditions such as time elapse velocity in the execution environment, program execution start time and execution termination time, adjusts the time elapse velocity and the program execution start time according to the determination of an analysis manager, executes the program till the execution termination time, monitors the execution environment, acquires an action record of the program, analyzes the action record, and clarifies the behavior of the program. Further, the program analysis system resets the analysis conditions based upon a result of analysis, re-analyzes, monitors communication between a sample and an external terminal, and varies the time elapse velocity set by the analysis manager to prevent time-out from occurring in communication.

摘要： A transaction mediation device stores transaction request information indicating estimates of profit and loss obtained by the first participant through the transaction; transaction provision information indicating estimates of profit and loss incurred based on a thing that the second participant obtains through the transaction; and behavior characteristic information indicating evaluation of behavior characteristics that affect the profit and loss of a transaction counterparty, and, for each of the one or more second participants, calculates, based on the transaction request information and the behavior characteristic information, a first expected profit that the first participant obtains through the transaction with the second participant and a second expected profit that the second participant obtains through the transaction with the first participant; and calculates and outputs a gross profit incurred from the transaction based on the first expected profit and the second expected profit.
