This article provides a concise overview of Zero Trust Architecture, detailing the five core pillars—identity and access management, device and endpoint security, network segmentation and access policies, application workload protection, and data protection and governance—along with network-, application-, and data-centric models, practical implementation steps (MFA, just-in-time privileges, microsegmentation), and the role of behavioral analytics and threat intelligence; it is a guidance piece on improving security posture rather than a report of an incident.
