Modern connected environments rely on secure Internet of Things (IoT) systems to ensure the integrity, confidentiality and availability of data. This unit introduces the fundamental principles and practices involved in securing IoT networks and infrastructures.

The unit begins by exploring IoT architectures, network design and secure-by-design principles, focusing on how security is integrated throughout the IoT lifecycle. It then examines key security mechanisms, including identity and access management, encryption techniques and threat mitigation strategies used to protect IoT systems.

Building on this foundation, the course introduces cloud-based IoT security and advanced approaches such as zero-trust models and privacy-preserving technologies. Learners will also gain insight into risk management and the challenges associated with securing distributed IoT environments.

Throughout the unit, learners will combine theoretical understanding with practical design concepts, developing the skills to design, implement and manage secure IoT network architectures.
