Special Title: From Infection to Digital Immunity: Self-Healing Multi-Agent Architectures for Autonomous IoT Defense
Abstract: Rapid IoT expansion exposes resource-constrained devices to automated cyber threats such as Mirai botnets, rendering traditional manual defenses obsolete. To address this challenge, we present an innovative defense framework that repurposes threat propagation mechanisms into autonomous countermeasures. This talk introduces two agent-based architectures: the Botnet Defense System (BDS) and its evolution, the Immune-Based Botnet Defense System (iBDS). BDS employs autonomous white-hat worm agents to penetrate infected devices, terminate malicious processes, and harden device security. Formally modeled with Agent-Oriented Petri Nets (PN2) and verified using NuSMV, BDS guarantees mathematically proven safety and stability. Building on this foundation, iBDS integrates biological immune principles—combining innate immunity and acquired immunity. Empirically validated on Raspberry Pi Zero and OpenWrt testbeds, the system neutralizes persistent attacks within minutes without human intervention. By bridging multi-agent systems, formal verification, and bio-inspired computing, this research establishes a resilient, autonomous cybersecurity framework for future IoT ecosystems.
