Identity management, Authentication, and Access control in IoT

  Introduction The Internet of Things (IoT) connects billions of devices—from smart homes to industrial sensors—creating immense opportunities and challenges. Among the most critical challenges is security . Ensuring that devices and users are properly identified, authenticated, and granted the right access is essential to prevent unauthorized control, data breaches, and cyber-attacks. In this blog, we will explore the three pillars of IoT security: Identity Management , Authentication , and Access Control , and how they work together to secure IoT ecosystems. 1. Identity Management in IoT Identity management (IdM) is the process of uniquely identifying devices and users within an IoT network. Unlike traditional IT systems, IoT involves devices with limited computational power, dynamic networks, and sometimes intermittent connectivity. Key Components: Device Identity: Every IoT device must have a unique digital identity, often stored in secure hardware like TPMs (Trusted...
