Data Encryption with SQL Server
Protecting the data with which you have been entrusted
Protecting data is a key challenge for every company. To make sure your company stays off the ever-growing list of data breaches, you’ll need to encrypt your data. But encryption is complex and hard to implement. How does encrypting data affect database performance? What data fields should you encrypt and why? And if you can’t encrypt all these fields, what else can you do to protect sensitive data?
Expert Tom Norman answers these questions and more. You’ll get a concise yet comprehensive overview of the major options to encrypt data within SQL Server—Transparent Data Encryption, cell-level encryption, and Always Encrypted—along with the appropriate situations where each method should be deployed and how each encryption method affects performance. You’ll also cover other data protection methods in SQL Server, from auditing to data classification. Join in to gain a deeper understanding of SQL Server encryption options and learn how to fully protect your data.
