Protecting the data stored in your database may have been at the top of your priorities recently, especially with the changes that were introduced earlier this year with GDPR.

There are a number of ways to protect this data, which until not so long ago would have meant either using an encrypted filesystem (e.g. LUKS), or encrypting the data before it is stored in the database (e.g. AES_ENCRYPT or other abstraction within the application).

Application-level encryption, on the other hand, is the best: it is the most flexible method with almost no overhead, and it also solves data in-flight encryption. Unfortunately, it is not always possible …
