The Effect of Virtual Network Technology in Computer Network Security

In the daily operation of computer network, data security problems such as theft, network instability and connection failure often occur, which pose a serious threat to data security. With the continuous expansion of the application scope of computer technology, the problem of network security has become more and more complex. The emergence of virtual network technology provides a new idea to solve the problem of network security. Through virtualization technology, computer networks can be effectively isolated management between different local area networks, to realize the security of data transmission, so as to improve the security of the network. Virtual network technology can ensure the safe flow of information in the virtual network, and improve the operation efficiency of the network through the flexible network architecture design. Therefore, exploring the effect of virtual network technology in computer network security has become an important topic to be studied urgently.
