We’ve all seen the recent news stories about companies whose data has been stolen by hackers. What was once a rare event has become all too common, and companies large and small are at risk. While it isn’t always possible to prevent intrusions, you can reduce the risk by encrypting your data. In this presentation, I’ll show you the four ways that SQL Server provides to encrypt data: hashes, cell-level encryption, database-level encryption (also known as transparent data encryption), and backup encryption. We’ll also discuss the keys required for each type of encryption and discuss how to protect the keys themselves.
