Abstract

As artificial intelligence (AI) becomes more deeply integrated into digital infrastructure, the landscape of cybersecurity is undergoing a fundamental transformation. While AI offers new tools to detect and prevent cyber threats, it also enables increasingly sophisticated attacks. This article explores the dual role of AI in cybersecurity-both as a defines mechanism and as a threat vector. It examines emerging cyber threats, such as deep fake-based fraud and automated hacking, and presents AI-driven solutions including anomaly detection, Behavioral analysis, and threat intelligence. The paper also discusses the ethical implications, regulatory challenges, and the urgent need for global cybersecurity resilience in an AI-dominated era.
