Collaborative device-level botnet detection for internet of things

Cyber attacks on the Internet of Things (IoT) have seen a significant increase in recent years. This is primarily due to widespread adoption and prevalence IoT within domestic critical national infrastructures, as well inherent security vulnerabilities endpoints. Therein, botnets emerged major threat IoT-based infrastructures targeting firmware such weak or default passwords assemble an army compromised devices which can serve lethal cyber-weapon against target systems, networks, services. In this paper, we present our efforts mitigate challenge through development intrusion detection system that resides device provide enhanced visibility thereby achieving hardening devices. The device-level presented here part research framework BTC_SIGBDS (Blockchain-powered, Trustworthy, Collaborative, Signature-based Botnet Detection System). We identify systematic review existing literature detailed design component framework. use signature-based scheme with trusted signature updates strengthen protection emerging attacks. evaluated suitability capability generation custom signatures two most famous IDS ISOT, IoT23, BoTIoT datasets assess effectiveness respect anomalous traffic typical resource-constrained network terms number alerts, rates, time peak CPU memory usage.
