| Standards status: Trial-use | Computable Name: EndpointAccessControlMechanism | |||
Endpoint access control mechanisms protect and manage access to healthcare endpoints, ensuring secure data exchange between systems.
They standardize methods to secure endpoints, ensuring interoperability and security.
In certain use cases requiring system scalability and flexibility, different profiles may be utilized based on the chosen access control mechanism. For example,
the Unified Data Access Profile (UDAP) uses JWT access tokens.
