Abstract
The application provides a network security processing method and device for a single data stream. The method comprises: obtaining an association analysis expression; the association analysis expression comprises flow table information of a single data stream to be analyzed and an association expression; constructing an abstract syntax tree based on the flow table information and the association expression; traversing nodes in the abstract syntax tree, calling a target code generation process corresponding to the nodes, and generating target code corresponding to the nodes based on the target code generation process; storing the target code in a code file to obtain a target code file; and performing network security processing on the single data stream based on the target code file. The method provided by the application can compile and generate code based on the association analysis expression of the single data stream to realize association analysis of the single data stream, thereby improving the efficiency of network security analysis and processing of the single data stream.
