Implementing Zero Trust Architecture in Modern Enterprise Networks

Abstract

Abstract With the way enterprise networks are changing with high cloud adoption rates, remote working populations and advanced forms of cyber threats, the traditional perimeter approach to security is no longer tenable. Zero Trust Architecture (ZTA) has become an innovative approach to cybersecurity that aims to overcome the weaknesses of the legacy systems due to the implementation of the set of principles of never trust, always verify. This paper will examine the theoretical backgrounds, essential elements, practical applications of ZTA in current business spheres. It offers a critical analysis of existing constructs, including NIST SP 800-207 and the Forrester ZTX framework as well as case studies in the industry, featuring Google BeyondCorp, the Zero Trust implementation at Microsoft, and the Zero Trust requirements at U.S federal government agencies. The comparative analysis used in the study provides both positive points, e.g. the improvement of access control, regulatory compliance, and threat mitigation, and negative ones, e.g. the need to integrate with the legacy infrastructure, the performance overhead, and organizational readiness. Lastly, the article suggests future directions and emerging trends such as the importance of artificial intelligence, blockchain-based identity, and deployment of Zero Trust in Internet of Things (IoT) as well as hybrid cloud ecosystem. Combining the learning of the scholarly world and the practices of organizations, this paper will provide an enterprise with a clear guide on how to implement Zero Trust without limits, vulnerability, and cognizance.
