Implement network security
Network security is an important measure to ensure unauthorized users cannot reach the services that you are protecting. Limiting what users can see is always a great idea, since they can’t compromise what they can’t see.
Apply network access restrictions
By default, Azure AI Services are accessible from all networks. Some individual Azure AI Services resources (such as Text Analytics, Face, Computer Vision, and others) can be configured to restrict access to specific network addresses - either public Internet addresses or addresses on virtual networks.
With network restrictions enabled, a client trying to connect from an IP address that is not allowed will receive an Access Denied error.
Note
For more information about configuring network access for Azure AI Services, see the Azure AI Services documentation.
