Zero Trust Security Architecture: Principles and Early Adoption

Abstract

The rising complexity of cyber threats and the shortcomings of the old paradigm of security models in the form of perimeter security has compelled organizations to look into other security paradigms. Zero Trust Security Architecture (ZTSA) is one solution that can be viewed as a proactive solution, focusing on rigid identity checking, least privilege access, and constant patrol, instead of trusting things within network boundaries. This study will look at the core concepts of Zero Trust such as micro-segmentation, identity and access management, and device security, and its initial implementation history within the enterprise setting. The analysis of implementation strategies, challenges, and case studies help the study to identify practical considerations that organizations need to realize when implementing Zero Trust frameworks. The results indicate that technical integration and organizational preparedness are problematic, but early adoption shows great potential of reducing security risks and resiliency. The article offers a theoretical background to organizations that are interested in adopting Zero Trust that can be added to the growing debate on the topic of contemporary cybersecurity strategies.
