Zero-Trust Security Architecture for Enterprise Information Systems

Abstract

Zero-Trust Security Architecture (ZTSA) for enterprise information systems is a modern cybersecurity paradigm that eliminates implicit trust and enforces continuous verification of users, devices, and applications regardless of location; by integrating identity-centric access control, least-privilege principles, micro-segmentation, continuous monitoring, and adaptive risk assessment, Zero-Trust enhances protection against advanced persistent threats, insider attacks, and cloud-based vulnerabilities while improving security posture, compliance, and resilience in dynamic enterprise IT environments.
