Abstract
This paper reviews the challenges of DGA (domain name generation algorithm) domain name and its traditional detection methods, pointing out the shortcomings of these methods in terms of real-time performance, accuracy and efficiency. With the continuous evolution of network attack means, DGA domain name has become an important means for attackers to escape security detection.
Therefore, it is crucial to develop efficient and real-time DGA domain name detection methods. In recent years, deep learning has made remarkable progress in the field of natural language processing, providing new solutions for DGA domain name detection. This paper details the method of DGA domain detection using LSTM model and Attention mechanism. By converting domain name strings into word vectors, the LSTM model is able to capture long-term dependencies in the sequence, while the Attention mechanism helps the model to focus on critical information more accurately.
The experimental results show that deep learning-based DGA domain name detection methods outperform conventional methods in terms of accuracy, real-time performance, and efficiency. This method can not only effectively identify the DGA domain name, but also reduce the false alarm rate and omission rate, which provides a strong guarantee for network security.
The contribution of this paper is to provide a new perspective and thinking for DGA domain name detection, and promote the development and progress of related technologies. In the future, we will continue to explore more effective DGA domain name detection methods to meet the changing network security challenges and protect user data security.
