Abstract

Abstract : Currently, the Android platform is the most popular mobile platform in the world and holds a dominant share in the mobile device market. With the popularization of the Android platform, large numbers of Android malware programs have begun to emerge on the Internet, and the sophistication of these programs is developing rapidly. While many studies have already investigated Android malware detection through machine learning and have achieved good results, most of these are based on static data sources and fail to consider the concept drift problem resulting from the rapid growth in the number of Android malware programs and normal Android applications, as well as rapid technological advancement in the Android environment. To address this problem, this work proposes a solution based on an ensemble classifier. This ensemble classifier is based on a streaming data-based Naive Bayes classifier. Android malware has identifiable feature utilization tendencies. On this basis, feature selection algorithm is introduced into the ensemble classifier, and a sliding window is maintained inside the ensemble classifier. Based on the performance of the subclassifiers inside the sliding window, the ensemble classifier makes dynamic adjustments to address the concept drift problem in Android malware detection. The experimental results from the proposed method demonstrate that it can effectively address the concept drift problem in Android malware detection in a streaming data environment.
