Artificial Intelligence (AI) transforms the way modern systems are designed, operated, and maintained, enabling higher levels of intelligence, security, and sustainability. By leveraging machine learning, data analytics, and automated decision-making, AI-powered systems can optimize resource utilization, predict and prevent failures, and enhance operational efficiency across various domains, including smart cities, transportation, healthcare, energy, and industrial automation. AI also strengthens cybersecurity by detecting threats in real time, identifying vulnerabilities, and responding to attacks with minimal human intervention. Intelligent algorithms contribute to sustainability goals by reducing energy consumption, minimizing waste, and supporting environmentally responsible practices. As organizations adopt AI-driven technologies, the development of smart, secure, and sustainable systems may help address complex societal challenges and building a resilient future. AI for Smart, Secure, and Sustainable Systems explores how AI can be leveraged to develop intelligent systems that improve efficiency, automation, and decision-making while ensuring security and resilience against cyber threats. It examines the role of AI in promoting sustainability through optimized resource management, energy efficiency, and environmentally responsible solutions across various sectors. This book covers topics such as cloud platforms, security and privacy, and sustainable development, and is a useful resource for engineering, security professionals, academicians, researchers, and scientists.
