Research on Network Information Security Perception Technology Based on Big Data

The network is easily interfered by various attacks, and these attacks are extremely rich, so the risk factors faced by network security are diversified. Network security perception is generally divided into three stages: situation element extraction, situation understanding and situation prediction. In order to better protect the sense of use and information security of individuals and countries, this paper studies the perception system based on the perception element extraction system of SDN honeynet from the perspective of big data. It is hoped that it can make a greater contribution to the development of network security and give full play to the practical application of this system.
