Firewall
Microsoft Azure allows you to create database-level firewall rules to help protect your data and prevent all access to your database. The Firewall grants access and control of your azure database based on IP addresses. You can specify which IP address can access your database. You can have a maximum of 128 firewall rules for your database.
Please note: By default your database will have an OPEN firewall rule which will accept all connections. It is highly recommended you change this rule.
In this section, you will learn how to manage your database firewall settings:
