Abstract: The rapid expansion of digital transformation has introduced unprecedented challenges to cybersecurity. Traditional perimeter-based defense systems are no longer sufficient to protect against sophisticated cyberattacks. Zero Trust Architecture (ZTA), a model rooted in the principle "never trust, always verify," is revolutionizing cybersecurity in the internet era. This paper explores the evolution, principles, implementation strategies, and challenges of ZTA. The study provides a comprehensive framework for adopting ZTA in diverse organizational settings, reinforced by case studies, tables, and figures to elucidate its components and practical applications.
