Cognitive Services Accounts Should Restrict Network Access

Description:

Network access to Cognitive Services accounts should be restricted. Configure network rules so only applications from allowed networks can access the Cognitive Services account. To allow connections from specific internet or on-premises clients, access can be granted to traffic from specific Azure virtual networks or to public internet IP address ranges.

Solution/Reference: 

To restrict access for Cognitive Services from public networks:
1. In the Azure portal, open Cognitive Services,
2. Select an item from the list, and open the "Networking" page,
3. In "Firewalls and virtual networks" select "Selected Networks and Private Endpoints" or "Disabled".
