Upgrade and Optimization of Virtual Network Security Management on Blockchain

In modern society, people are increasingly paying attention to network security management. However, with network virtualization, new errors would occur in the security environment of the network, which makes it difficult to maintain and execute problems effectively. From this point, it can be seen that the difficulty of network security management is becoming increasingly difficult, which brings great hidden dangers to enterprises and even their future development. This article organically combines blockchain technology with virtual network security management, aiming to create a stable network security environment. Virtualization technology can enable enterprise personnel to efficiently integrate multiple servers and effectively solve network security issues. In order to meet the current network security management needs, it is necessary to strengthen the monitoring of servers in the process of building a virtual management platform to improve network security. In the long run, strengthening the perception and protection of network data through the rational allocation of server resources is the key to ensuring the healthy and coordinated development of various network platforms. Finally, the experiment proved that the bit error rate of the system communication encryption designed in this article remains below 10% in different channel numbers, which performs better than other technologies.
