Safety detection model construction method and system based on fine-grained gating mechanism

The invention relates to the technical field of computer information security, in particular to a security detection model construction method and system based on a fine-grained gating mechanism, and the method comprises the following steps: creating a data set containing network traffic information; preprocessing the data set to obtain a fine-grained content feature sequence; constructing a safety monitoring model, inputting the fine-grained content feature sequence into an attention gating module of the safety monitoring model, and then inputting the output into a safety monitoring model judgment module to obtain a prediction label for judging whether the fine-grained content feature sequence is safety information or not; the two modules are trained and optimized to output an optimal value, the optimal value is brought back to the quantity module to obtain a final prediction label, and whether an alarm is given out or not is judged according to the final prediction label. According to the method, the fine-g
