This is your weekly summary of Compose news for those changes and updates which can make your life easier. In this edition, we talk about how to protect your own data, along with a look back at the week in Compose Articles.
We get mail at Noteworthy and one recent mail asked: "Apart from TLS, what other encryption does Compose support?". It's a good question, especially as the GDPR deadline approaches, so let's look at Compose and Encryption.
Protecting your data
Because of the nature of a managed system, it is theoretically possible for operators to be able to see data in the various databases. For that reason, we do advise that where you are storing sensitive personal information, you encrypt it before storing it in the database. How you do this will depend on your application's language, framework and the database capabilities you are prepared to give up or engineer around to ensure the system continues to work.
For example, in this article we looked at encrypting fields using Ruby and Mongoid to implement symmetrical encryption on particular fields in a document. As another example, PostgreSQL users may want to look at the pgcrypto extension which adds cryptographic functions to the database itself.
These are examples are different approaches to the same issue, encrypting a field, one doing the encryption in the application, the other allowing an application to ask the database to do the encryption for it using an extension.
Encryption at Rest
If you have Compose Enterprise then your disk storage is protected by volume level encryption at rest on the servers.
If you don't have Compose Enterprise, then currently and generally, we do not have volume level encryption at rest on those servers. We are moving towards enabling encryption at rest on everything and will have a Noteworthy update on that progress by May 15th.
In the past week of Compose Articles, we've looked at bulk uploading data into Elasticsearch and the latest news on database updates being released into the wild:
In Elasticsearch, Bulk Uploading and the High-Level Java REST Client - Part 1, we show how to use the high-level REST client for Elasticsearch and the Bulk API to load up your data efficiently, complete with a full Java example. There's more to come as we'll touch on some techniques to really boost the upload.
The past week saw the launch of Cockroach DB 2.0 and SailsJS 1.0, some interesting future PostgreSQL developments, Tensorflow in the browser and more. It's all in our Friday NewsBits Roundup at Compose where we like to keep you informed.
That's it for this week's Noteworthy at Compose. Onwards to next week!
