Connecting External System with SAP ABAP Server using SNC

Hi Esxperts,

We have our SAP servers configured with SNC. And we want to connect external GRC tool with SAP server.

Please let me know how to configure external GRC application to use with SNC connection to the SAP server.

We have enable SNC with sap sso security product in SAP ABAP system.

What are the required configuration from External system side?

Thanks,
