Influence Analysis of Network Density on White-Hat Worm and Basic Strategy for Botnet Defense System

A cybersecurity system called Botnet Defense System (BDS) uses white-hat worms to defend IoT systems against malware like Mirai. This paper analyzes the influence that whitehat worms come under from network structure. The analysis is focused on network density. Using agent-oriented Petri nets, we expressed IoT systems having different network density. Through the simulation evaluation of the model, we revealed that if the network density is low, the white-hat worms become inefficient. In addition, based on the result we proposed a basic strategy for BDS: If a given IoT system has low network density, the BDS should launch as many worms as possible.
