What is Zero Trust?
Zero Trust is a modern architectural approach to network security that rejects the concept of a "protected perimeter" in favor of the principle " Never Trust , Always Verify ". Unlike traditional perimeter-based security models (where internal systems are presumed safer), Zero Trust assumes threats can exist both inside and outside the network, requiring continuous verification of all resources and users regardless of location.
Zero Trust architecture requires continuous verification of every user, device, and application before granting resource access. This includes multi-factor authentication, device verification, network segmentation, and continuous monitoring. Zero Trust is particularly relevant for cloud environments, remote work, and hybrid infrastructures.
Standards and Frameworks:
Zero Trust is described in NIST Special Publication 800-207 "Zero Trust Architecture" and ISO/IEC 27001 standards. Frameworks from NIST, CISA, and other organizations also exist.
