windows-hardening (Chef Cookbook)
This cookbook provides recipes for ensuring that a Windows 2012 R2 system is compliant with the DevSec Windows Baseline.
- Windows Server 2012
- Windows Server 2012 R2
- Windows Server 2016
- Windows Server 2016 Nano Server
This cookbook aims to be the go-to-resource to implement hardening for Windows environments. In order to achieve that plan to cover the requirements of
- CIS Windows 2012R2
- CIS Windows 2016
- STIG Windows 2012R2
Any contributions to achieve that are welcome!
Use Chef resources wherever possible. Some Chef resources we use to manage Windows:
If no Chef resource is available, we prefer to use Powershell or Powershell DSC.
Testing the cookbook
This cookbooks ships with a test-kitchen setup to verify that the implementation follows the DevSec Windows Baseline:
Chef Server and Chef Compliance
If you use Chef Server, you can bootstrap a node and run a Chef Compliance against them it. It is recommended to use an EC2 instance in a Chef environment, made up of a Chef Server and a Compliance Server. The following command can be used for bootstrapping a node.
knife ec2 server create --node-name windows-test --flavor t2.medium --image ami-29eb7e5a --security-group-ids sg-238e5744 --user-data win-userdata.ps1 --winrm-user Administrator --winrm-password Ch4ng3m3 --ssh-key emea-sa-shared -r 'recipe[base-win2012-hardening::enable_winrm_access]'
Please note the following:
- To bootstrap a Windows node using Knife you need a predictable password. The
win-userdata.ps1file, in this repo, provides this.
- You need a security group that allows winrm access and RDP access.
- We set a run-list. The
enable_winrm_accessrecipe prepares the node for a manual Compliance scan.
Applying at scale
This cookbook is currently in development. It does not cover all requirements to provide a fully hardened Windows environment yet. Any contributions are welcome to improve the cookbook. If you wish to apply this at scale, use a role and add the cookbook to its runlist, there is no need to apply a specific recipe.
