An OpenStack Security Guide epub was released this week, and among the contributors was our friend Andrew Hay.

Trying to find this info before was like locating a piece of hay in a haystack (not an Andrew Hay – he would be considerably easier to find in a haystack). We use OpenStack for the Cloud Security Alliance training labs, and I had to figure out a lot of this myself through painful reading of barely-legible documentation.

The book was created in a 5-day sprint so it’s a little rough. Some sections are pretty light but they intend to improve it over time. The sections on hardening the Keystone identity service, picking a hypervisor, hardening core services such as the message queue, and secure networking, are pretty decent. You can’t secure OpenStack just by reading this – you need to understand the platform first – but this guide will definitely point you in the right directions.
