Comprehensive Evaluation of Zero Trust Architecture and Its Implementation Challenges in Large-Scale Enterprise Cybersecurity Infrastructures
Keywords:
Zero Trust Architecture (ZTA), cybersecurity, enterprise security, access control, network security, cloud securityAbstract
Zero Trust Architecture (ZTA) has emerged as a critical cybersecurity model in response to evolving cyber threats, especially in large-scale enterprise infrastructures. Unlike traditional perimeter-based security approaches, ZTA operates on the principle of “never trust, always verify,” ensuring strict identity authentication and continuous monitoring. Despite its theoretical robustness, implementing ZTA in large enterprises poses significant challenges, including scalability, interoperability, policy management, and integration with legacy systems. This paper comprehensively evaluates ZTA by reviewing existing literature, analyzing practical deployment challenges, and identifying possible solutions for large-scale enterprise adoption. Key insights are drawn from previous studies to highlight the effectiveness, limitations, and future directions of ZTA.
