Towards a Secure Internet of Things: A Comprehensive Study of Second Line Defense Mechanisms

摘要: The Internet of Things (IoT) exemplifies a large network sensing and actuating devices that have penetrated into the physical world enabling new applications like smart homes, intelligent transportation, healthcare cities. Through IoT, these consolidated in modern to generate, share, aggregate analyze amount security-critical privacy sensitive data. As this consolidation gets stronger, need for security IoT increases. With first line defense strategies cryptography being unsuited due resource constrained nature, second mechanisms are crucial ensure networks. This paper presents comprehensive study existing standardized protocols analyzes three aspects: Intrusion Detection Systems (IDS), Prevention (IPS) Response (IRS). We begin by providing an overview protocol stack, its layers defensive systems IoT. From there, we build our narrative presenting extended taxonomy IDS, IPS IRS classifying them on their techniques, deployment, attacks, datasets, evaluation metrics data pre-processing methods. then thoroughly review, compare research proposals context, considering unique characteristics involved systems. Based extensive analysis systems, also identifies open challenges directions effective design such networks, which could guide future area.
