A comprehensive catalogue of all transactions, dependencies, and services with associated IDs is a potential outcome of an effective ZT implementation because it helps to map the data flows and interactions among the assets and entities in the ZTA. This catalogue enables the ZTA to enforce granular and dynamic policies based on the context and attributes of the transactions, dependencies, and services. It also facilitates the monitoring and auditing of the ZTA activities and performance.

ZTA models in terms of access decisions are based on the principle of ''never trust, always verify'', which means that each access request is handled just-in-time by the policy decision points. The policy decision points are the components in a ZTA that evaluate the policies and the contextual data collected from various sources, such as the user identity, the device posture, the network location, the resource attributes, and the environmental factors, and then generate an access decision. The access decision is communicated to the policy enforcement points, which enforce the decision on the resource. This way, ZTA models apply a consistent access model throughout the environment for all assets, regardless of their location, type, or ownership.

In a ZTA, a policy decision point (PDP) is a logical component that evaluates the incoming signals from an entity requesting access to a resource against a set of access determination criteria, such as identity, context, device, location, and behavior1.A PDP then makes a decision to grant or deny access, or to request additional information or verification, based on the policies defined by the policy administrator1.A policy enforcement point (PEP) is a logical component that uses the incoming signals from the PDP to open or close a connection between the entity and the resource1.A PEP acts as a gateway or intermediary that enforces the decision made by the PDP and prevents unauthorized or risky access2.

To respond quickly to changes while implementing ZT Strategy, an organization requires a mindset and culture of continuous risk evaluation and policy adjustment. This means that the organization should constantly monitor the threat landscape, assess the security posture, and update the policies and controls accordingly to maintain a high level of protection and resilience. The organization should also embrace feedback, learning, and improvement as part of the ZT journey.
