Overview of Zero Trust Architecture Trend and Advancement in Information Security

Abstract

Zero Trust Architecture (ZTA) has become a trending and revolutionary architecture in information security, transitioning from the conventional concept of perimeter security to a ‘never trust, always verify’ model. This study examines the concepts of ZTA, technological advancements and ZTA implementation in various sectors like finance, healthcare, and government. ZTA transformation technological innovation domains are 5G, the blockchain, and quantum computing, which define the future of ZTA adaptability.  Similarly, this study aims to establish the role of ZTA in mitigating insider threats, its position on compliance with regulatory frameworks, and its relevance as a cybersecurity standard among various industries. Principles such as least privilege, continuous verification, encryption, least privilege, and multi-factor authentication allow ZTA to validate each access request quickly, regardless of the location. The evolution from the traditional security model tackles the susceptibilities inherent in remote access, cloud computing and mobile workforce. The ZTA technique has mitigated insider risks, lateral movement attacks and advanced persistent threats by imposing stern access control and continuous monitoring. ZTA enhances security environments and improves organization’s tenacity since it enhances Least-Privilege access and real-time threat detection. This study seeks to establish how organizations can benefit from ZTA in safeguarding important assets in today’s dynamic technological environment.
