Zero Trust Security Model Shifts Focus From Network Location to Per-Request Verification

Zero trust is a security approach that replaces automatic network-based trust with explicit, risk-informed decisions for every resource request involving users and workloads. Rather than a single product, it requires collaboration across application owners, identity teams, endpoint operations, and data stewards to map high-value resources and access paths. Authorization should be expressed in terms of specific business actions and objects, with enforcement applied at the resource layer for each meaningful request rather than only at network entry points. Organizations are advised to pilot the model on one high-value workflow with fallback options before expanding, and to retire old credentials and access paths only after sufficient evidence is gathered. Ongoing governance should center on protected resources and access policies, with regular reviews of privileged roles, policy exceptions, and service identities.
