An effective way to prevent local area network virus intrusion

Individual users infected with the virus, the use of stand-alone anti-virus software can be cleared; However, in the enterprise's network, a machine once infected with the virus, it will automatically copy, send and use a variety of means to continuously cross infected local area network users. The forms of computer viruses and the way of transmission are increasingly diversified therefore, the antivirus work of large enterprise network system is no longer like a single computer virus detection and elimination as simple, but need to establish multi-level, three-dimensional virus protection system, but also have a sound management system to set up and maintain the virus protection strategy.

An anti-virus system of an enterprise network is built on each local area network antivirus system, should be based on each local area network anti-virus requirements, establish the LAN anti-virus control system, set up targeted anti-virus strategy.

(1) Increase safety awareness

Eliminate the virus, subjective initiative plays a very important role. The spread of the virus, often because of the internal staff of the virus is not enough to understand the spread of the virus transmission channels there are many kinds, through the network, physical media and so on. Kill the virus, first of all to know what the virus is, it's how the harm is, know the virus harm, improve the safety awareness, to eliminate the cancer of the battle has been half successful. At ordinary times, enterprises should start from the strengthening of security awareness, the daily work of hidden virus to increase alertness, such as the installation of a popular network version of anti-virus software, regular update virus definition, the file before the operation of dubious killing, weekly killing virus, reduce the number of shared folders, When file sharing, as far as possible to control the rights and add passwords, etc., can be very good to prevent the spread of the virus in the network.

(2) Beware of mail

With the popularization of the Internet, e-mail has become an indispensable medium in people's work. It is convenient and quick to improve the efficiency of people at the same time, but also inadvertently become the accomplice of the virus. Some data show that more than 90% of the virus is now transmitted by mail.

Although the spread of these viruses is very simple, but this is not just a technical problem, but also should educate users and businesses, let them take appropriate measures. As long as users are vigilant, do not open questionable mail, you can reject the virus.

(3) Select the network version of antivirus software

The choice of a sophisticated network version of the virus "killer" is vital. Generally speaking, whether the killing is thorough, the interface is friendly, convenient, whether centralized management is the decision of a network anti-virus software three major elements.
