    摘要: By synthesizing the map of an entire network, it provides a method for detecting OSI Reference Model layer-2 switches and evaluating the status of the inter-connection of the layer-2 switches. The NMT(102) which implements the SNMP manager queries the specified management IP-addresses and receives responses from the SNMP agents implemented on the layer-2 switches (103,104,105). From the management information in the responses, the existence of the layer-2 switches is confirmed and the MAC address and port information mapping table MvP table is constructed. Based on the MvP table the inter-connection information of the layer-2 switches is detected.

    摘要: A system for detecting and tracing a (D)DoS attack and identifying the attack source, which system simplifies the judgment reference to determine whether a (D)DoS attack is present. The number of source addresses of the packets transmitted via the Internet line is monitored. When the number of the source addresses has reached a predetermined number or a predetermined ratio within a predetermined time, it is judged that an unauthorized attack is present. Moreover, where the hop number of the packet is different from a hop number corresponding to the transmission source information, the packet is judged to be malicious.

    摘要: This invention aims to provide a technique that, in wireless network environments, enables the Manager to collect network management information (MIB data in the case of SNMP based network management), which the Agent has stored during periods of disconnection, after connectivity to the mobile nodes has recovered. In a wireless network environment, the Agent (201) has a unit for storing the management information related to network devices with appropriate label information, while the Manager (101) has a unit for sending the Agent a request for a label-specified data, and getting the data which the Agent has stored in Management Information Store 207. The above unit enables the Manager (101) to seamlessly collect the information pertaining to the period of disconnection, which the Agent (201) has stored in Management Information Store 207, after detecting recovery of the connectivity.

    摘要: A system detects the presence of illegal access attacks. The device for analyzing and diagnosing network traffic divides packets into k (k>0) types based on protocol type and port number, etc., a component observing the number of distinct values of one or more pre-specified fields in packet header for each packet type, for all packets that have transited the observation points in a network, an element observing the number of distinct values of one or more pre-specified fields in the packet payload for each packet type, for all packets that have transited the observation points in a network, and a diagnosis element determining whether the network is abnormal when the number of distinct values observed in fields of each packet type crosses a specified ratio-threshold within a predetermined interval. This enables detection of small-scale DoS attacks with little change in addresses number, improving illegal access detection accuracy.

    摘要: A network security monitoring apparatus and a network security monitoring system manages “permitted” or “not permitted” communication between nodes based on an access policy. A network security monitoring system includes nodes 31,32,33, application server 20, router 40, and network security monitoring apparatus 10 deployed in the network. The network security monitoring apparatus 10 judges whether the nodes are permitted to communicate with other nodes in the network or not based on the access policy, and repeatedly transmits data to block the communication between nodes judged as “not permitted” at fixed time intervals until the access policy is changed from “not permitted” to “permitted”. This invention enables to block communication between nodes defined as “not permitted” for communicating with other nodes in the access policy, and to allow communication between nodes defined as “permitted” for communicating with other nodes in the access policy.
