Malware Behavior Modeling with Colored Petri Nets

Part 9: Various Aspects of Computer SecurityInternational audienceWe propose a solution which provides a system operator with a mechanism that enables tracking and tracing of malware behavior which – in consequence – leads to its detection and neutralization. The detection is performed in two steps. Firstly single malicious activities are identified and filtered out. As they come from the identification module, they are compared with malware models constructed in the form of Colored Petri nets. In this article we present our approach to malware modeling. Proposed method was implemented and practically verified in laboratory environment with emulated malicious activity at the hosts level
