In this post I’ll describe how we used CFEngine to apply fixes to apache and nginx to defuse the infamous poodle bug. The post is a bit rushed, in the hope it may still be useful to someone. The policies use bundles and bodies from either the standard library or from our own. The libraries are not shown here but the names speak for themselves… hopefully 🙂
As you’ll probably know, the “trick” on the server side is not to allow secure (erm…) connections to use anything older than TLSv1. In order to do that, we decided to
- deploy a conf.d snippet to set the appropriate protocol versions as a default;
- disable the same directive in existing configuration files to avoid weaker directives take priority;
- restart the server if/when the configuration gets fixed.
