SQL Express Encryption

Data security is important when personal data is stored such as contact information, banking details, credit card information, and more. Encryption is used to protect from unauthorize access to this data. Here are some ways on how to protect your data:

Provide access to relevant persons only

Encrypt the folder containing all database files

Starting with the 2016 SP1 version of SQL Server Express, the Always Encrypted feature is built-in. Here is what it does.

Always Encrypted protects sensitive data by offering column-level encryption.

It relies on necessary keys to decrypt data to be stored on the client-side.

These keys are never available to the Database Engine which separates the owner of the data and those who manage it.
