Design And Implementation Of A Virus Defense System For Enterprise Networks

As rapid development and extensive popularization of computer and Internet technology, different business activities of enterprise management have to be based on Internet/Intranet environments. However, the Internet is open and free with flexibility in the applications, at the same time it has the higher security requirements. Once the network security has been seriously threatened, even in a state of paralysis, it will generate tremendous economic losses to enterprises, society, and the whole country. How to prevent the information network system from hackers and computer virus invasion has become one of the important tasks to be considered for enterprise information construction.At present, the computer virus can do harm to many enterprises such as in hardware damage, data loss or abnormal use, which result in great losses every years. As a result, the computer virus defense has got more and more attention in enterprises. Different from traditional virus, new type of virus has a variety of channels, more rapid and more covert, with boarder spreading scale and greater harm.Large enterprises have continuously developed their networks while also continuing to expand the scale. Due to their business needs, they have branches and subsidiaries in different areas. Therefore, the huge local Intranet and the Intranets in different areas are linked together and formed a huger Internet network. How to get the internal corporate network virus-related information, to carry out a comprehensive, intuitive and accurate monitoring, and to make effective clearance, is a new problem that enterprise IT personnel must face with.The paper focuses on the current computer virus defense and control work in enterprises, with the actual situation and needs, design a set of enterprise network anti-virus system. The system can provide a more comprehensive, convenient, intuitional and accurate virus monitoring platform, reduce the damage and risk, which virus is bringing to network and application constantly, and provide security to the enterprise information construction.The paper covers the following main tasks:1. Collecting and analyzing the virus types in interior enterprises and confirming the used types of anti-virus product.2. Knowing the real situation about virus defense of the company headquarters and branch network architecture, network applications.3. Making technical analysis of virus in order to provide technical reference for the design of virus defense system.4. Planning the virus defense system management platform and designing a suitable system model.5. Executing and testing the whole system.
