Research on Network Information Security and Protection System Based on Computer Big Data

The traditional network information security protection system has poor network security protection performance, and a large number of data are attacked when attacked. Therefore, it is very necessary to design a network information security protection system based on the game model of attack and defense. This paper proposes an active anti-leakage security mechanism and a comprehensive information security protection technical scheme that adopts comprehensive identity authentication access control, real-time monitoring of file operations and data security storage. This paper designs an active anti-leakage information security protection system. This paper systematically describes the design criteria, technical principle and implementation scheme of the enterprise network information security protection system, and proposes the prospect of the system. The system implements eKey-based network identity authentication and secure login, real-time monitoring of file operations based on a two-layer monitoring mechanism, and network-based file encryption. The system effectively improves the security protection ability to prevent internal active leaks and external technology theft.
