    Abstract: The present disclosure relates to a monitoring area determination apparatus that determines, for software to be monitored, a monitoring area of a tampering detection feature call function (hook) incorporated together with a tampering detection feature. The apparatus generates a CFG based on a binary of the software, temporarily determines, based on the CFG, a part of a source code of the software into which a hook is incorporated and temporarily determines, based on the CFG, in accordance with a predetermined rule, a monitoring area of the hook whose incorporated part is temporarily determined, sequentially selects the hook whose incorporated part has been temporarily determined, adds a node to the temporarily-determined monitoring area of the selected hook based on a predetermined allowable processing delay, and determines, as the monitoring area of the selected hook, a monitoring area after the node is added to the temporarily-determined monitoring area of the selected hook.

    IPC: G06F11/36

    CPC classification number: G06F11/3604

    Abstract: A program analysis apparatus includes a first code block extraction means for extracting a first code block having a specific property from codes included in a binary of a program, a second code block extraction means for extracting a second code block performing a predetermined sensitive operation from the codes included in the binary of the program, a relationship information acquisition means for acquiring relationship information indicating a relationship on a control flow between the first code block and the second code block, a backdoor score calculation means for calculating a backdoor score based on content of the predetermined sensitive operation in the first code block and performing addition and subtraction of the backdoor score with respect to the first code block based on the relationship information, and an output means for outputting the first code block and the backdoor score for the first code block.

    Abstract: Provided is an analysis system that can analyze the degree of impact of vulnerability on individual systems. An 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 a system to be diagnosed. A calculation unit 12 calculates an evaluation value, for each vulnerability, which indicates degree of impact of the vulnerability on the system to be diagnosed. Specifically, the calculation unit 12 calculates the evaluation value, for each vulnerability, based on the number of the attack patterns that include the vulnerability focused on as the attack means and the number of the segments indicated by each attack pattern that includes the vulnerability focused on as the attack means.

    Abstract: A communication terminal in an ad hoc network has a wireless communication part, a lower layer protocol part operating on a lower layer of the network, and an upper layer protocol part operating on an upper layer of the network. The lower layer protocol part has a routing table holding route information including a destination IP address and a next hop IP address associated with each other. The upper layer protocol part has: an information sharing management part transmitting and receiving a message including an IP address of the local communication terminal to and from a neighbor communication terminal through the wireless communication part by broadcast communication; and a route information registration part registering, into the routing table, the route information including the IP address included in the message received by broadcast communication as the destination IP address and as the next hop IP address.
