Chef Cookbook - SSH Configuration

This Chef cookbook will configure SSH on Linux servers to be compliant with Route 1337 security policies. There are a few versions of the configuration depending on the recipe that is chosen

SSH Config Recipes

1. standardssh.rb is the standard recipe suitable for use on internal LANs or where networks are trusted to be secured
2. hardenedssh.rb is a recipe for use in DMZs or other networks where sophisticated attacks are either expected, or where more stringent policies exist

Changes Performed

1. Configures OpenSSH server with custom security settings depending on recipe selected.
2. Ensures OpenSSH is installed, configured and enabled/running

Requirements

1. Chef (Tested on Chef 13.6.4)
2. Linux chef-clients (Tested on Ubuntu 14.04, Ubuntu 16.04, Ubuntu 18.04, and CentOS 7.2 but kitchen will let you test anything you want)
3. The openssh cookbook from Chef Supermarket

Installation Tips

1. We personally use Berks to install this into Chef servers, because it will grab the dependencies for you as well.
2. You must set the attribute ['r1337-sshconfig']['sshpolicy'] to hardened if you want something stronger than the default. For most people the default is fine.

Limitations

1. None so far :)

Known Issues

1. None so far :)

Use Cases
