Effective prevention of LAN virus intrusion

This article is from People's Network

Individual users can use stand-alone antivirus software to clear viruses. However, once a machine is infected with a virus in the enterprise network, it automatically copies, sends, and uses various means to repeatedly cross-infect other users in the LAN. Computer Virus forms and transmission channels are becoming increasingly diverse. Therefore, the anti-virus work of large enterprise network systems is no longer as simple as the detection and removal of a single computer virus, A multi-level and three-dimensional virus protection system is required, and a complete management system is required to set up and maintain protection policies for viruses.

An enterprise network anti-virus system is built on the anti-virus system of each LAN. According to the anti-virus requirements of each LAN, a local network anti-virus control system should be established to set up targeted anti-virus policies.

(1) Increase security awareness

Putting an end to viruses and subjective initiative play an important role. The spread of viruses is often due to the lack of knowledge of virus transmission methods by employees within the company. There are many channels for virus transmission, including networks and physical media. To scan and kill a virus, you must first know what the virus is, how it harms, the dangers of the virus, the security awareness, and the battle to eliminate the cancer have been half done. At ordinary times, enterprises should begin to strengthen their security awareness to increase their vigilance against the hidden viruses in their daily work. For example, they should install a public-recognized anti-virus software on the Internet and update the virus definitions on a regular basis, scan and kill unknown files before running, scan and kill viruses once a week, reduce the number of shared folders, and try to control permissions and add passwords when sharing files, can effectively prevent the spread of viruses in the network.

(2) Careful email

With the popularization of the Internet, email box has become an indispensable medium in people's work. It is convenient and quick, while improving people's work efficiency, and has no intention of becoming a virus culprit. According to some data, more than 90% of the viruses are spreading through emails.

Although the spread of these viruses is very simple, it is not just a technical problem, but also to educate users and enterprises to take appropriate measures. The virus can be rejected as long as you are always cautious and do not open suspicious emails.

(3) Select the online anti-virus software

Selecting a powerful online virus "killer" is crucial. In general, whether the detection and removal are complete, whether the interface is friendly and convenient, and whether or not centralized management is the three major factors that determine a network anti-virus software.
