Security is one of the deciding factors for an organization when opting to put their data in the cloud. Microsoft provides the best security by not only securing the Azure SQL Database, but by also securing the data centers.

To connect to an Azure SQL Database, the machines or the client IP address should exist in the firewall settings. If not, the connection request is denied.

Azure SQL Database allows SQL and Windows Authentication as well. An organization can sync their domain with Azure, thereby allowing users to connect from domain accounts instead of SQL logins. Organizations can also create Active Directory Groups and give access to the group instead of giving access to individual user domain accounts.

In addition to this, you can use Row-Level security and dynamic data masking to further secure the data by allowing users to only see the data they need in order to do their work.

Azure SQL Database also provides proactive monitoring to detect threats such as SQL injection as and when they happen.
