Today we see encryption growing at an accelerating rate in data centers, for a confluence of reasons. A trite way to summarize them is “compliance, cloud, and covert affairs”. Organizations need to keep auditors off their backs; keep control over data in the cloud; and stop the flood of data breaches, state-sponsored espionage, and government snooping (even by their own governments).

Thanks to increasing demand we have a growing range of options, as vendors and even free and Open Source tools address this opportunity. We have never had more choice, but with choice comes complexity – and outside your friendly local sales representative, guidance can be hard to come by.

For example, given a single application collecting an account number from each customer, you could encrypt it in any of several different places: the application, the database, or storage – or use tokenization instead. The data is encrypted (or substituted), but each place you might encrypt raises different concerns. What threats are you protecting against? What is the performance overhead? How are keys managed? Does it all meet compliance requirements?

This paper cuts through the confusion to help you pick the best encryption options for your projects. In case you couldn’t guess from the title, our focus is on encrypting in the data center: applications, servers, databases, and storage. Heck, we will even cover cloud computing (IaaS: Infrastructure as a Service), although we covered it in depth in another paper. We will also cover tokenization and discuss its relationship with encryption.

We would like to thank Vormetric for licensing this paper, which enables us to release it for free. As always, the content is completely independent and was created in a series of blog posts (and posted on GitHub) for public comment.
