Research on Computer Network Information Security Problems and Prevention Based on Wireless Sensor Network

With the continuous improvement of China’s scientific and technological level, computer network has become an indispensable part of people’s daily life. It can not only effectively improve the efficiency of production and life, and shorten the distance between people, but also further promote the speed of China’s social and economic development, which has a positive impact on the realization of China’s modernization. Under the new information security demand environment at present, we should pay attention to the related information security work and formulate effective security measures and strategies. In order to effectively prevent these information security problems, people should actively adopt firewall technology, encryption technology, network access control technology and network virus prevention technology for effective protection. This paper analyzes the security problems in the application of wireless sensor networks and explores the mechanism of defending information security, hoping to strengthen the security and stability of wireless sensor networks through effective measures, so that people can better enjoy the convenience brought by the network age.
