ABSTRACT
With the rapid development of network technology, the spread speed and number of variants of malware have increased significantly, posing a serious threat to network security. Traditional detection methods based on feature codes have been unable to cope with the increasingly complex malware environment. Therefore, this study aims to explore the application potential of support vector machine (SVM) in malware detection. In order to provide an efficient and accurate detection scheme with generalization ability, SVM is adopted as the core classification algorithm in this study, and a multi-level feature selection mechanism is constructed by combining static analysis and dynamic behavior feature extraction techniques. By comparing the performance of different kernel functions, parameter optimization strategies are introduced to improve the classification accuracy of the model. The SVM-based malware detection method shows excellent classification ability when processing high-dimensional feature data, its detection accuracy is improved by about 15% compared with traditional methods, and it also has strong robustness and anti-interference ability. In addition, this research innovatively proposes a hybrid feature representation method that integrates static and dynamic features. It effectively solves the problem of insufficient spatial information of a single feature, thus further enhancing the detection effect of the model. In summary, support vector machine has significant advantages in the field of malware detection, and provides an important reference for the construction of intelligent network security protection system in the future.
