Abstract: PROBLEM TO BE SOLVED: To search an unauthorized router 22 existing in the Intranet 10. SOLUTION: In the Intranet 10, a transmitting side router searcher 26 transmits an IP packet for inspection to a network connection apparatus being inspected. Source and destination of the IP packet for inspection have the IP address of a receiving side router searcher 28 and the network connection apparatus being inspected, respectively, and the data part is loaded with a TCP packet having specified ID information. The network connection apparatus being inspected generates a reply IP packet for a received IP packet for inspection. Since the source and destination of the reply IP packet are the source and the source of the IP packet for inspection, respectively, the reply IP packet is received by the receiving side router searcher 28 of the Internet 19 when the network connection apparatus being inspected is a router.

Abstract: PURPOSE: To execute a numerical plan problem in a system where the intention of a planner can reflect. CONSTITUTION: The variable of the numerical plan problem is graphically displayed on a display device 10. A graphics object is operated by a mouse 11 and an inductive restriction is added to the corresponding variable and the value of the corresponding variable is changed with an operation for the graphics object. The planner of the inductive restriction which is set for the graphics object can be recognized with color display. A new solution is obtained by the method 6 of operation research with a distance with the previous solution as a target function based on a restriction peculiar to the problem and the inductive restriction.

Abstract: PROBLEM TO BE SOLVED: To obtain a method for tracking an access chain which does not depend on the data contents of a packet and its system. SOLUTION: The log data of the packet coming in and going out a network are stored in a log box. In such a case, the data size and detection time of the packet are recorded. When illegal access is made to a target computer, an illegal access chain is tracked on the basis of the log information. The access chain tracking is performed as follows. The change of the packet data size at the time in a 1st connection and the change of the packet data size at the time in a 2nd connection are calculated from the log data. The shapes of graphs formed by these sequences are compared and when the shapes are similar, the connections are decided as being included in the same chain.
