Abstract:
Zero Trust Architecture (ZTA) is widely regarded as a major change in cybersecurity frameworks. It aims to overcome the problems of perimeter-based security models that are less effective in the digital ecosystem, which is getting more and more interconnected. Due to the fast implementation of cloud computing, remote-working environment, mobile devices, and Internet of Things (IoT) technologies, conventional trust-assumed networks are not viable solutions to sophisticated cyber threats anymore. Zero Trust is based on the main idea of "never trust, always verify", thus it enforces continuous authentication, strict access controls, micro-segmentation, and real-time monitoring of all users, devices, and network resources.
This review paper traces in detail the transformation, the component parts, and the principles-of-operation of Zero Trust Architecture. It references the existing models like NIST SP 800-207 and determines the feasibility of ZTA in different organizational settings. The article also discusses the difficulties in switching to a Zero Trust model, such as the problem of integrating with legacy systems, performance overhead, and complexity of the implementation. Besides that, the paper looks at the latest breakthroughs and the future of ZTA, with new technologies and innovations like AI-driven access control, identity-centric security, and adaptive trust mechanisms to name a few. The review, in essence, demonstrates that ZTA is necessary as a contemporary cybersecurity paradigm to fight off advanced persistent threats, diminish attack surfaces, and reinforce organizational resilience.
