Hi @志村武信 / SHIMURA,TAKENOBU , to ensure that only authorized people can access the data or the model when training on the model or using the model, you can use Azure role-based access control (Azure RBAC). Did you get a chance to check how to configure Azure Open AI with managed identities: https://learn.microsoft.com/en-us/azure/cognitive-services/openai/how-to/managed-identity
Azure OpenAI does supports VNET's and Private Endpoints also: https://learn.microsoft.com/en-us/azure/cognitive-services/cognitive-services-virtual-networks?context=/azure/cognitive-services/openai/context/context
Is this something you are looking for?
I hope this helps. Let me know if you have any questions.
Regards,
Vasavi
