Abstract
Rapid urbanisation of global populations requires novel approaches to improve the efficiency, sustainability and livability of our cities. In this paper, we present a survey of Artificial Intelligence (AI) in Cybersecurity for Digital Ecosystem and its Applications in Cloud Computing, IoT Devices, Blockchain Systems. This study combines AI, cybersecurity and software engineering to propose a framework for deploying scalable and adaptive security solutions. We analyze the effect of AI-driven cybersecurity using a combination of experimental testing and simulation to measure threat detection accuracy, time-to-response, and system resilience. The overall improvement in security metrics and user-trust demonstrates the power AI have to truly make a difference in digital ecosystems. It also contributes to a rapidly emerging new field of cybersecurity technologies and provides useful information for engineers and policymakers.
