Based on network security issues and the daily use of information platforms, it is very important to design and implement emergency response in line with network information security, which can help organizations respond to network security incidents in a timely and effective manner, and minimize losses. This paper adopts a more complex encryption algorithm and a stronger key management mechanism to provide higher security. From the perspective of business and service candidates, it focuses on the design of the system, as well as the problems existing in the use process and the improvement plan.
