Microsoft improves security for Azure SQL Database

Microsoft is giving database administrators working with Azure SQL Database a new suite of security tools to check out.

A new Always Encrypted feature will be available as a public beta by the end of the month. It allows users to encrypt sensitive data within an application using their own keys without relinquishing those keys to the Azure SQL Database. It's a feature that lets companies maintain better control over critical applications they want to keep as secure as possible. 

Microsoft's Transparent Data Encryption feature, which allows the encryption of a database without altering the application itself, will be generally available by the end of October. The company will automatically rotate the encryption keys for a database using the feature every 90 days, without end users having to worry about it.
