Hey everyone! I'm on the Blue Team and currently managing a Windows Server environment that isn't very secure. I'm looking to properly configure the Domain Controller and GPO settings to enhance security. Can anyone recommend step-by-step guides or checklists for hardening Windows Server? I'm particularly interested in the best GPO settings for Domain Controllers, covering areas like password policies, audit settings, and user rights management. Additionally, if you have practical rules that can be applied through GPO or any scripts/templates that would help, I'd really appreciate it. I've gone through Microsoft and CIS documents, but they can be confusing and overwhelming when trying to apply the recommendations correctly. Suggestions for monitoring and log management would also be great! Thanks!

Check out the NIST and STIG standards for the US DoD. They're publicly available and provide comprehensive guidelines on every setting you need to adhere to for security—super valuable for any federal network compliance.
CIS Workbench and their Benchmarks will serve you well. If you already have a CIS membership, check out their build kits—they can help reduce frustration. Look for training videos on the CIS Workbench; they explain how to apply the guidelines without all the confusion.
The CIS benchmarks lay out exactly what you need to do, along with the reasons behind it. I suggest handling settings in batches—start with less impactful settings to avoid breaking things. Hit around 80% compliance gradually, documenting any issues as you go so you can revert changes when necessary.
It can definitely feel overwhelming, especially if you're new to hardening! Start with CIS policies for GPO as a bare minimum. I'd recommend checking out tools like Ping Castle and Purple Knight for hardening recommendations. Just try making 5 non-disruptive changes to start building momentum without breaking things. Also, grab the Policy Analyzer to load CIS CSC or Microsoft secure baseline—it'll help you a lot!
Totally agree! Just start with manageable changes, and you’ll build your way up. It's more about gradual improvements than diving in headfirst.
You might want to explore DISA STIG as well; it's pretty comprehensive. Just keep in mind that you’ll need to do a good bit of research and testing to really understand how those settings will play out in your environment.
Yes! The training videos were super helpful for me when I started using their resources. Don't hesitate to leverage them!
