Problems solved by technology

However, it sometimes takes time from virus detection to completion of the disinfection process
If it takes time, the range of damage will gradually expand, potentially causing significant damage to the network
[0005] In addition, viruses that access files over the network, lurking in other computers on the network, are difficult to detect until they are active
Even if the virus starts to act and the virus is detected, it will take time to investigate the computer where the virus is hidden and remove the virus, and there is a problem of damage expansion

Embodiment Construction

[0018] Hereinafter, the best mode for carrying out the invention will be described with an outline including its principle. Then, a detailed description will be given.

[0019] Set up a decoy that can be accessed through the network on the computer (monitoring computer) that monitors virus intrusion, accept access to the decoy through the network, obtain communication information, and detect the intrusion of the virus. When the virus invades the decoy, According to the correspondingly acquired communication information, the computer that is the source of the virus is detected, and the computer that is the source of the virus (infected computer) is subjected to a virus attack process to suppress the virus activity through the network. And, send a detection report to the administrator of the computer that is the source of the virus.

[0020] Here, a bait with lower safety is prepared to promote virus penetration. In order to reduce the security of the bait, it is achieved by making ...

Abstract

There is disclosed a system for detecting virus infection in a network and preventing the virus infection. Decoy means (13, 14, 15) accessible via the network (1) are arranged on a storage device (12). The system includes: communication information analysis means (16) for detecting virus intrusion into the decoy means (13, 14, 15) and upon detection of the virus intrusion, detecting a computer as a source of the virus from the communication information acquired upon the virus intrusion; and computer attack means (17) for performing virus attack process to the virus source computer for suppressing action of the virus via the network. Attack of the computer attack means (17) by a monitoring computer (10) is continued until a computer (5) infected with virus is identified and the virus is removed by an administrator.

Description

Technical field [0001] The present invention relates to a technology for identifying the source of infection when a computer connected to a network is infected with a virus, and preventing infection to other computers connected to the same network. Background technique [0002] Among computer viruses, there are viruses that invade the shared files of computers such as servers, access predetermined files and programs, destroy them, or rewrite them to cause erroneous actions. You can use a predetermined program to detect the presence of a virus. The program judges whether it is a virus based on the file name of the virus, the behavior of the virus, etc. When a virus is detected, the administrator of the computer implements necessary processing to remove the virus. Various techniques for detecting viruses and issuing vaccines have been introduced (refer to Patent Document 1: Japanese Patent Laid-Open No. 2002-259149). [0003] However, the above-mentioned conventional technology has...
