Abstract	The rapid integration of artificial intelligence into critical digital infrastructure is transforming conventional information systems into increasingly autonomous environments capable of monitoring, analysing, predicting and acting with limited human intervention. AI is now being incorporated into cloud platforms, industrial control systems, healthcare infrastructure, financial networks, transportation systems, energy grids and enterprise information systems. While this integration creates significant opportunities for operational efficiency, predictive decision-making and adaptive automation, it also introduces new cybersecurity risks. AI-integrated infrastructure expands the attack surface by combining conventional cyber vulnerabilities with threats targeting machine-learning models, training data, AI agents, application programming interfaces and autonomous decision-making processes. This paper examines emerging cybersecurity risks associated with autonomous digital systems and proposes a comprehensive security framework integrating conventional cybersecurity, AI-specific controls, continuous monitoring, human oversight and resilient system architecture. Particular attention is given to adversarial machine learning, data poisoning, prompt injection, model theft, supply-chain attacks, autonomous agent compromise, identity manipulation and cascading failures in interconnected infrastructure. The paper further examines the importance of zero-trust architecture, secure AI development, explainability, model validation, continuous red teaming and incident response. A conceptual framework is proposed for securing AI-integrated infrastructure across the lifecycle from data acquisition and model development to deployment, monitoring and recovery. The study argues that cybersecurity for autonomous digital systems must evolve from perimeter-based protection towards adaptive, intelligence-driven and resilience-oriented security models capable of addressing both traditional and AI-specific threats.
