Zero Trust is more than a security model. It is a rejection of implicit trust inside networks, systems, and applications. Identity-driven access control enforces boundaries through verified credentials, context checks, and continuous authentication. Every request is evaluated. Every session is reassessed. Nothing inside is inherently safe.
Identity Zero Trust Access Control places identity at the core. The system decides access rights based not only on who the user is, but on what they are doing, where they are connecting from, and how they are behaving. It treats user accounts, service accounts, and machine identities with equal scrutiny. Tokens expire. Roles adjust. Policy reacts in real time.
Strong identity verification means integrating multi-factor authentication, hardware-based security keys, and robust identity providers. Authorization is granular and adaptive, often using Role-Based Access Control (RBAC) or Attribute-Based Access Control (ABAC). Every resource has its own rules, enforced without exception.
