Abstract: The current surge in interconnected devices, which includes the Internet of Things (IoT) devices and the continually expanding cloud infrastructure, marks a new era of digital transformation and convenience. This transformative wave is reshaping industries, ushering in the age of smart cities, autonomous vehicles, and effortless remote collaboration. Yet, the growing complexity and reach of these technologies bring an accompanying increase in potential vulnerabilities and security risks. Thus, this study delves into the convergence of artificial intelligence (AI), cloud computing, and IoT security. It investigates how these state-of-the-art technologies can be leveraged to protect networks, data, and devices, presenting inventive solutions to address the ever-evolving threat landscape. Additionally, it sheds light on the challenges posed by AI-powered techniques and offers insights into future trends, making it a valuable resource for researchers, students, and cybersecurity professionals.
