Abstract

The invention provides a Web attack detection method based on an HTTP (Hyper Text Transport Protocol) request text and related equipment. The method comprises the following steps: collecting an HTTP request text in network traffic; the HTTP request text is preprocessed, so that a coding vector is generated; a pre-trained memory focus processing neural network (MFPNN) model is utilized to detect the coding vector to obtain a prediction vector, and the MFPNN model is constructed by combining a bidirectional long short-term memory (BiLSTM) neural network model with a multi-head attention mechanism; and performing calculation based on the prediction vector to obtain a classification result of the Web attack. According to the embodiment of the invention, the accuracy and true positive rate of Web attack detection can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of network security, in particular to a Web (World Wide Web) attack detection method and related equipment based on HTTP (Hyper Text Transfer Protocol, hypertext transfer protocol) request text. Background technique [0002] Severe network attacks often lead to catastrophic data leakage and loss. In order to block attacks on web applications, the first task is to be able to accurately detect web attacks. The information memory ability and focus processing ability of the traditional deep learning detection model are not strong, resulting in low detection accuracy and true positive rate; and URL (Uniform Resource Locator) data is usually used as input data, which may miss the attack payload. Affects the accuracy and true positive rate of the model. Contents of the invention [0003] In view of this, the purpose of this disclosure is to propose a method for detecting web attacks based on HTTP reques...
