摘要： A recording medium recording a network shutdown control program permitting suitable preventive measures to be taken. A detector monitors each network segment to be managed, and on detecting a communication fulfilling a predetermined condition, the detector generates a detection notification and sends the notification to a quarantine manager. On acquiring the detection notification generated by the detector of the local device or a detection notification generated by a remote network shutdown device, the quarantine manager generates a shutdown operation request in accordance with quarantine policy stored in a quarantine policy storage, and sends the request to a communication shutdown unit. In accordance with the shutdown operation request, the communication shutdown unit sets shutdown data identifying a target of shutdown and controls packets to be input to and output from the network segment so that the packets may be shut off or passed.

摘要： In a network relay device, unauthorized access from an internal computer to an external network is detected, an unauthorized destination service port used for the unauthorized access is specified, and a substitute port is allocated. A service relay unit and the internal computer are instructed to use the substitute port instead of the unauthorized destination service port, and an unauthorized access notification is sent. Mutual conversion of the unauthorized destination service port and a substitute service port is carried out, to relay a packet between an internal network and the external network.

摘要： A computer-readable recording medium recording a worm detection program which is preferably usable for a large-scale network and is capable of detecting worm communication with little information. A worm detection device which runs this program has a switching hub function, and comprises five physical ports that are network interfaces, a communication acquisition section, and a worm detector, for example. The communication acquisition section acquires ICMP type3 (destination unreachable message) packets going out of the physical ports. The worm detector determines whether the packet communication is worm communication, based on information on the ICMP type3 packets obtained for each source MAC address by the communication acquisition section and worm criteria set for determining whether communication is worm communication.

摘要： A computer-readable recording medium recording a worm detection parameter setting program for setting an appropriate worm detection parameter for target environments. When a log reader loads a communication log created within a prescribed time period, a log classifier classifies the entries of the communication log into categories based on communication contents. A frequency distribution creator analyzes the entries of a category, counts the number of appearance of each worm detection parameter value for each object of a preset network unit, and creates frequency distribution information. A threshold derivation unit analyzes the frequency distribution information and derives a threshold value that is used for determining whether a worm is propagating. An output unit outputs to an output device the threshold value for the worm detection parameter for the category, together with the frequency distribution information created by the frequency distribution creator, thereby providing a user with the information.

摘要： An unauthorized access detection device capable of detecting unauthorized accesses which are made through preparation, in real time. When a packet travels on a network, a key data extractor obtains the packet and obtains key data. Next an ongoing scenario detector searches an ongoing scenario storage unit for an ongoing scenario with the key data as search keys. A check unit determines whether the execution of the process indicated by the packet after the ongoing scenario detected by the ongoing scenario detector follows an unauthorized access scenario being stored in an unauthorized access scenario storage unit. Then a report output unit outputs an unauthorized access report depending on the check result of the check unit.

A monitoring information-collecting section collects monitoring information including the network events detected by the monitoring devices on networks. A malicious apparatus group-deriving section retrieves a corresponding piece of the event information from an event information storage device, and derives, based on the retrieved piece of the event information, apparatuses that are involved in relevant detected network events which belong to the predetermined type of network events and of which addresses of senders or recipients are same, as a malicious apparatus group involved in the predetermined type of malicious access. A storage section stores information on each derived malicious apparatus group. An output section outputs a list of the each derived malicious apparatus group.
