Security And Privacy Issues In IoT Systems

Authors: Dipankar Chatterji

Abstract: The rapid expansion of Internet of Things (IoT) systems has introduced significant security and privacy challenges due to the massive interconnection of devices, sensors, and communication networks. IoT environments collect, transmit, and process large volumes of sensitive data, making them highly vulnerable to cyberattacks, unauthorized access, and data breaches. This study examines the major security and privacy issues in IoT systems, including weak authentication mechanisms, insecure communication protocols, device vulnerabilities, and data leakage risks. It also explores the architectural structure of IoT systems and identifies potential attack surfaces at device, network, and application layers. Furthermore, the study discusses modern security solutions such as encryption techniques, lightweight authentication protocols, blockchain integration, intrusion detection systems, and AI-based threat detection. Privacy concerns related to user data collection, tracking, and storage are also analyzed in detail. The findings highlight the need for robust, scalable, and energy-efficient security frameworks to protect IoT ecosystems. The study concludes that addressing security and privacy challenges is essential for ensuring trust, reliability, and safe adoption of IoT technologies.
