Research on Computer Network Information Security Based on Big Data Technology

Internet big data is related to our personal privacy and property security. In serious cases, it also affects the security of confidential information of related companies. Therefore, big data must be protected to prevent criminals from stealing our personal privacy, property information and corporate secrets. Based on this research background, the paper designs the design of computer network security defines system. After the system design is implemented, the system is tested accordingly. According to the test results, the computer network security defines system designed in this paper can actively detect and effectively prevent security threats in the network, thereby ensuring that the network can Normal and safe operation. The computing network security defines system can also provide effective ideas for future network security protection and achieve further expansion of security defines.
