An Effective Cloud-Based Active Defense System against Malicious Codes

Abstract : With the rapid development of cloud computing technique, network security has attracted more and more attention. Of all the network threats, malicious code is the major one. Due to the surge of number and species diversity of the malicious code, it is intractable for the existing antivirus techniques to defense all of the attacks. In this paper, we construct an effective cloud-based active defense system against malicious code. The constructed system utilizes the honey-pot subsystem to collect threaten data, and multiple behavior analysis engines work in parallel to generate a comprehensive program behavior analysis report. Furthermore, there are intelligent algorithms running on several computing servers to achieve automatic intelligent analysis on the reports. Associated with the multiple scan engines form a comprehensive, reinforced and more intelligent active defense system.
