Design of Security Audit and Early Warning Mechanism Based on Cloud Platform

In order to understand the design of security audit and warning mechanisms for cloud platforms, a research on the design of security audit and warning mechanisms based on cloud platforms has been proposed. The security audit system proposed in this paper consists of three functional modules: audit information recording, audit information signing, and audit information management. It adopts key technologies such as Web Services and digital signatures to achieve functions such as obtaining, analyzing, and storing user information in the database. Secondly, based on the implementation of network security auditing, the system ensures the security and trustworthiness of data by combining tuple and shard signatures on database table entry information. Compared with the existing security audit system implementation schemes on cloud platforms, this scheme has high security and practicality, and has good portability.
