Abstract:Aiming at the problem that the traditional campus network security defense means can no longer deal with the security threat of smart campus under the current big data background, a design scheme of smart campus security management and control platform based on big data technology is proposed. In this scheme, the smart campus system is layered and classified to design the security protection mechanism, which realizes the granular protection management of the smart campus security;The big data technology is used to build a smart security brain, which solves the problems of data confusion and data association in smart campus, and realizes data fusion storage in smart campus;Fully perceive the security situation of smart campus through the intelligent operation management platform, and realize the intelligent linkage of risk prediction, security early warning, security disposal and protection and reinforcement.Through simulated attack test and security risk assessment, after deploying the smart campus security platform, the security defense capability of the smart campus is significantly strengthened and the security risk level is significantly reduced. Through practical application analysis, the security alarm and self-treatment capability of the smart campus are also significantly improved. Key words: smart campus; intelligent and safe brain; data fusion; safety management and control platform; security situation
