Encryption Options for Azure SQL

Overview:  With all IT storage, we are looking for encryption at rest and making sure the data is encrypted “over the wire” until it is stored storage.  For encryption in transit, Azure SQL supports TLS/SSL versions 1.0, 1.1,and 1.2.  If possible got for TLS 1.2.

Azure SQL Server Transparent Data Encryption (TDE) related to encryption at rest by encrypting the log and data files on the storage; Azure enforces TDE as the default on databases.  TDE can be turned off on your Azure SQL instance.

Backups should also be encrypted, and if TDS is enabled on Azure, your backups are also automatically encrypted.  Tip: Validate your restore of Azure Backups to another instance.

Column encryption is useful for encrypting a column within a table.  I prefer to use a Key Vault and use a SQL column to point to the database for things like tokens and secrets, but something like credit card numbers column encryption is ideal.

Always Encrypted allows for one or more columns to be encrypted within a database.  Client application shall decrypt and provides for separation where database owners/access cannot validate/view the encrypted column/columns.

Tree Testing and Heuristic Reviews - Ux for dummies

I was speaking to two Ux experts in a meeting and they referred to Tree Testing when discussing Information Architecture and the users working there way around a new SaaS product.  "Tree Testing" is not a term I had heard before so they showed me this site and it fantastic.

I'm more familiar with Heuristic Reviews - that I find useful for improving UI/UX using an iterative approach that suits Agile nicely.
