The Zero Trust Security Model and Its Application in Organizations
Keywords:
Zero Trust, cybersecurity, identity and access management, network segmentation, remote work securityAbstract
This article aims to examine the conceptual foundations, architectural components, and practical applications of the Zero Trust security model within diverse organizational contexts, highlighting both its strategic benefits and implementation challenges. A narrative review methodology with a descriptive analysis approach was used to synthesize recent academic and industry literature published between 2022 and 2025. Sources were selected based on relevance to Zero Trust principles, implementation strategies, technological components, and behavioral considerations. The review focuses on key themes including identity and access management, continuous authentication, policy enforcement, and user behavior within cybersecurity frameworks. The Zero Trust model redefines organizational security by eliminating implicit trust and requiring continuous verification for every access request. Key components such as identity verification, multi-factor authentication, micro-segmentation, and real-time monitoring work together to prevent lateral movement and minimize the attack surface. The model has been effectively applied in government, enterprise, and small-to-medium business environments and has proven particularly valuable in hybrid cloud and remote work settings. Benefits include improved security posture, regulatory compliance, and adaptability to evolving digital infrastructures. However, organizations face challenges related to technical complexity, implementation costs, workforce resistance, and skills shortages. Despite these obstacles, phased adoption and cultural alignment can facilitate successful deployment. Zero Trust represents a significant shift from perimeter-based security toward a dynamic, behavior-aware, and policy-driven model that addresses the demands of modern cybersecurity threats. Its comprehensive and flexible architecture provides organizations with the tools to build resilient and adaptive security environments, though successful implementation requires strategic planning, investment, and ongoing education.
