Network security Mode analysis based on big data environment

In recent years, driven by the trend of big data and cloud computing, various complex security issues in the traditional security mode have gradually emerged. On the one hand, new, persistent, and advanced attack threats emerge in an endless stream. The use of ransomware, Oday vulnerabilities and even more threatening APT attacks cannot be detected and prevented by traditional security protection equipment. On the other hand, with the explosive growth of Internet traffic, the number of deployed security devices has gradually increased and the network environment has become increasingly complex, resulting in massive amounts of data that cannot be effectively analyzed and utilized. Therefore, how to effectively analyze the network security mode in the big data environment has become an important link facing the current network security problems.
