Azure Storage provides a secure way to store data in the cloud. Security strategies include using a shared access signature (SAS) to grant delegated access to data objects, and using Client-Side Encryption, HTTPS, or SMB 3.0 to secure data in transit between an application and Azure. Additionally, Azure Storage offers role-based access control, which allows administrators to assign specific roles and permissions to users. Finally, Azure Storage also provides encryption at rest, which ensures that data is encrypted while stored in the cloud. These strategies help to ensure that data is secure and protected from unauthorized access.
