Introduction

Security is a major concern for organizations when migrating to the cloud, and so organizations are hesitant to do so. Microsoft provides strong security protection at the physical, logical, and data layers of Azure services. Microsoft data centers are among the most secure data centers in the world.

Azure SQL Database provides multiple layers of security to control access to databases using SQL Server or Active Directory (AD) authentication as well as firewall rules, which limits access to data through role-based permissions and row-level security.

Azure SQL Database provides proactive security using dynamic data masking, automated auditing, and threat detection.

It also provides transparent data encryption to encrypt data at rest, and Always Encrypted to encrypt data at rest or in motion.

This lesson covers all of these security mechanisms and how to implement and use them to secure an Azure SQL database.
