Azure Cosmos Db Accounts Should Have Firewall Rules

Description:

Firewall rules should be defined on your Azure Cosmos DB accounts to prevent traffic from unauthorized sources. Accounts that have at least one IP rule defined with the virtual network filter enabled are deemed compliant. Accounts disabling public access are also deemed compliant.

Solution/Reference: 

To configure your Azure Cosmos DB firewall and add IP rules:
1. Go to the "Firewall and virtual networks" section of your Cosmos DB account.
2. Select "Selected networks".
3. Add the IP addresses or ranges you want to allow.
