Recipes

apache-hardening::hardening (default)

This recipe is an overlay recipe for the apache2 cookbook and applies apache-hardening::hardening

Add the following to your runlist and customize security option attributes

"recipe[apache-hardening]"

This hardening recipe installs the hardening but expects an existing installation of Apache2.

Tests

For local testing you can use vagrant or docker to run tests locally. You will have to install Virtualbox and Vagrant or docker on your system. See Vagrant Downloads for a vagrant or Docker Downloads package suitable for your system. For all our tests we use test-kitchen. If you are not familiar with test-kitchen please have a look at their guide.
