HSCN technical guidance

Summary

Guidance, policy and best practice documents covering all technical aspects of HSCN. Documents on this page will be regularly reviewed and updated by NHS Digital as required.

Forms

HSCN ANM firewall change requests

Any end-user organisation requiring a firewall change to the HSCN ANM service to access non-standard ports/protocols for business-critical reasons must complete the HSCN ANM firewall change request form.

Once completed, this must be submitted to the NHS Digital Data Security Centre for assessment. The impact of the change will be assessed and a decision will be made to approve or not. Any successful requests will be forwarded to the ANM supplier for action.

The NHS Digital National Service Desk will feedback all resolutions via the local service desk support route.

The completed form should be sent to the NHS Digital National Service Desk via the end user organisation's local service desk route rather than via the CN-SP.

To request a change to a QoS configuration, download the change request form.

On the form, provide as much detail as you can, including: full contact details; information about the application and the reason for the configuration change; and the QoS class, IP address, and port/protocol (if applicable).

Email the completed change request form to the NHS Digital National Service Desk (NSD).

For further details and guidance see HSCN QoS - change requests and end-to-end configuration.
