Abstract

Web threats pose the most significant cyber threat. Websites have been developed or manipulated by attackers for use as attack tools. Existing malicious website detection techniques can be classified into the categories of static and dynamic detection approaches, which respectively aim to detect malicious websites by analyzing web contents, and analyzing run-time behaviors using honeypots. However, existing malicious website detection approaches have technical and computational limitations to detect sophisticated attacks and analyze massive collected data. The main objective of this research is to minimize the limitations of malicious website detection. This paper presents a novel cross-layer malicious website detection approach which analyzes network-layer traffic and application-layer website contents simultaneously. Detailed data collection and performance evaluation methods are also presented. Evaluation based on data collected during 37 days shows that the computing time of the cross-layer detection is 50 times faster than the dynamic approach while detection can be almost as effective as the dynamic approach. Experimental results indicate that the cross-layer detection outperforms existing malicious website detection techniques.
