Understanding Zero Trust Network: A Comprehensive Guide

Understanding Zero Trust Network: A Comprehensive Guide What is Zero Trust Network? Zero Trust Network (ZTN) is a security model that requires every user, device, and application within a network to be authenticated and authorized before accessing any resource. The principle behind ZTN is to never trust anyone or anything by default, regardless of their location, and to always verify their identity and credentials before granting access. How does Zero Trust Network work? In a ZTN architecture, all resources are segmented into micro-perimeters, creating an isolation layer around each resource that is only accessible to authorized users or devices. The authentication process involves multiple factors, such as usernames, passwords, multi-factor authentication (MFA), device posture assessments, and contextual awareness, which includes the user’s behavior patterns, location, and time of access. The authorization process involves granular access control policies that determine what spe
