Abstract :

Enterprises steadily emerging into the borderless digital ecosystem, traditional security paradigms are in a poor position to cope with the increasing complexity of modern cyber threats. Zero Trust Architecture (ZTA) has become a new direction to enterprise security whereby the defense paradigm has moved from the perimeter focus to an adaptive identity focused one. The Zero Trust model, in turn, runs on the principle of never trust, always verify any validation of the users, devices, and applications must be done continuously before letting users into the sensitive resources. In this paper we delve into the core concepts of Zero-Trust Architecture, dissecting the underpinnings microsegmentation, least privilege access and continuous monitoring. It examines how cutting-edge technologies including artificial intelligence (AI), machine learning (ML), and identity access management (IAM) play together to help build resilient ZeroTrust frameworks. This also discusses how integration of Zero Trust with both cloud native environments and remote work has been challenging due to scaling, operation complexity and user experience. It also shows real world case studies of when Zero Trust principles are implemented, and what practices should be avoided. Adopting a Zero-Trust model would give organizations more firepower to stop lateral movement, stem insider threats and evolve in an ever-changing threat landscape. This paper is a comprehensive guide for security professionals, IT leaders and decision-makers who want to harden their enterprise cyber resilience in a post perimeter world.
