Application Design of Data Security Pool System Based on Network Security Data Link Technology

In this paper, a prototype system is established to support dynamic adjustment and optimized deployment of the security service chain based on security logs and simultaneously a management framework is design for such a security service chain. For dynamic adjustment of the security service chain, a security rule expert database is established to analyze the log information pushed by third-party security network elements, match such information with the triggering conditions in the security rule expert database, and promptly adjust the security service chain according to preset rules after security events are discovered. By modeling the optimized deployment process of the security service chain and calling the designed heuristic algorithm, the deployment of the service chain can be achieved and the designed intelligent service chain system can have its functionality and performance verified accordingly. As can be seen from the experimental results, this system can help construct a virtual real network security resource pool, detect security events (if any) in seconds and also adjust the security service chain automatically in minutes. Therefore, the current system design is a solution that can minimize the consumption of virtual resources under corresponding conditions.
