Abstract
With the wide application of Web applications, its security threats are increasingly severe, and security vulnerability detection and protection have become the key link to ensure the security of information system. This paper proposes a hybrid vulnerability detection model and dynamic protection strategy based on deep learning in the current Web application security field, such as low detection efficiency, high false positive rate and lagging protection measures. Firstly, a multi-dimensional feature library including SQL injection and cross-site sc ript is constructed, and an improved LSTM-GRU neural network is used to perform feature extraction and pattern recognition, which effectively improves the accuracy of vulnerability detection. Secondly, a dynamic protection mechanism based on behavior analysis is designed to monitor user request and application response in real time, and combine with rule matching and machine learning algorithm. The experimental results show that the detection accuracy of the proposed method on the OWASP Benchmark test set reaches 96.8%, which is 15.3% higher compared with the traditional method, and the false positive rate is reduced to 2.1%. At the same time, the dynamic protection mechanism can effectively resist zero-day attacks, and the average response time is controlled within 50ms. The innovation point of this research is the combination of deep learning technology with the traditional rule engine, which realizes the integrated solution of vulnerability detection and protection, and provides a new technical path and practical guidance for Web application security. The research results have important theoretical value and practical significance for improving the security of Web application system.
