Security Considerations

TLS SHALL be used. This national extension enforces authentication and authorization of access to the Care Services Selective Supplier using the IUA profile with basic access token. Consequently, the Find Matching Care Services [ITI-90] request must authorize using the [ITI-72] transaction of the IUA profile.

The traceparent header is required, as described in Trace Context header.

Security Audit Considerations

Note that the same audit message is recorded by both Care Services Selective Supplier and Care Services Selective Consumer. The difference being the Audit Source element. Both sides record to show consistency between the message sent by the Consumer and the action taken at the Supplier.

The actors involved shall record audit events according to the Audit Event for Find Matching Care Services for Read by the Care Services Selective Supplier and Consumer or the Audit Event for Find Matching Care Services for Query by the Care Services Selective Supplier and Consumer.
