Securing the healthcare ecosystem: Zero trust architecture protecting patient data across multiple access points

Mohile, Kedar (2025) Securing the healthcare ecosystem: Zero trust architecture protecting patient data across multiple access points. World Journal of Advanced Engineering Technology and Sciences, 15 (3). pp. 371-378. ISSN 2582-8266

This article examines the implementation of Zero Trust Architecture (ZTA) in healthcare environments to address the growing cybersecurity challenges facing the industry. The article explores how healthcare organizations are adopting "never trust, always verify" principles to protect sensitive patient data across increasingly distributed systems. The article details core principles of Zero Trust in healthcare contexts, analyzes healthcare-specific security challenges, outlines key implementation components, and presents case studies of successful transformations. Through examination of identity and access management, micro segmentation strategies, endpoint security for medical devices, and AI-driven risk assessment, the article demonstrates how Zero Trust frameworks significantly improve security postures while maintaining clinical workflow efficiency. The findings reveal that healthcare organizations implementing comprehensive Zero Trust approaches experience substantial reductions in unauthorized access, improved breach containment, decreased security incidents, and enhanced compliance posture while achieving operational benefits.
