CloudGuardian: Safeguarding the Internet of Things (IoT) - Navigating security frontiers in cloud-connected ecosystems

Kapitel i bok, 2024

In recent times, the proliferation of Internet of Things (IoT) devices and the seamless integration with cloud computing have revolutionized the technological landscape. This chapter delves into the critical aspects of understanding and securing cloud-connected IoT ecosystems. This chapter commences with an exploration of the convergence between IoT and cloud computing, emphasizing the architecture and functionality of cloud-enabled IoT systems. It sheds light on the transformative impact of cloud integration on IoT devices, highlighting the intricacies of their interconnectedness. A substantial portion of this chapter is dedicated to unveiling vulnerabilities and threats inherent in cloud-connected IoT ecosystems. Common vulnerabilities, such as insecure communication channels and lack of device authentication, are dissected. Simultaneously, this chapter elucidates on threats, including data tampering and denial-of-service attacks, underscoring the imperative need for robust security measures. Authenticating and authorizing interactions within cloud-integrated IoT environments is then discussed, emphasizing the importance of multifactor authentication and secure identity management. The exploration extends to authorization protocols, particularly role-based authorization, fortifying the security framework. Safeguarding data takes center stage in the subsequent section, addressing encryption strategies for IoT data in the cloud and privacy considerations. This chapter navigates through end-to-end encryption, securing data at rest, user consent, and compliance with data privacy regulations. Furthermore, this chapter outlines comprehensive strategies for ensuring the security of the entire lifecycle of IoT devices in the cloud. From secure provisioning and onboarding to real-time monitoring and over-the-air updates, each facet is meticulously examined. This chapter concludes by exploring future trends and challenges in cloud-based IoT security. It anticipates the impact of emerging technologies, such as edge computing, and underscores the challenges related to scalability and interoperability, providing a holistic view of the evolving landscape of cloud-connected IoT security.
