For the November meeting, I was honored to be invited to speak at the Minneapolis PASS user group here in the Twin Cities. I put together a bit of an unconventional session covering the basics of hashing and encryption, but as an introduction for DBAs. We focused on how those techniques work technically, where they appear in SQL Server, and what they protect against - or not - from a security point of view. There was also some good discussion about what issues you confront when recommending which of the many encryption features (TDE, column encryption, encrypted backup, Always Encryped, etc.) to implement in your organization and why.
I did not actually demo the features in SQL Server. Instead we looked at hashing and encryption of values at a lower level using a PowerShell demo.
Deck and demos are attached. Enjoy!
