This invention belongs to the technical field of security auditing in computer data processing, and relates to a database auditing method and system based on intelligent translation and three-layer association. The method includes the following steps: synthesizing an authorization seed tag and writing it into the system kernel shared memory area; extracting network mapping instruction clusters and native control command byte sequences containing underlying communication source port parameters corresponding to random source port identifiers; stripping port information to generate a unique legitimate addressing index upon successful verification; extracting fine-grained instruction slice signals; constructing memory coordinate offset vectors indicating specific harmful action behavior characteristics; continuously mirroring and copying the corresponding human natural language bit phrase sequences; and encapsulating and outputting a high-aggregation semantic warning data packet. This invention addresses the vulnerabilities in the association between terminal identity and database operations, the insufficient intuitive readability of operational behaviors, and the need to improve the security of cross-layer information fusion in multi-layer architectures in traditional database auditing methods.
