I recently came across the server 2012 Secuity guide apart of the “Secuirty Compliance Manager” which covers the Secuity Hardening of RDS 2012.
This document provides the best practices when securing server 2012 and RDS 2012.
Please see the link below:
Windows Server 2012 Security Baseline
Microsoft Security Compliance Manager
To access the Windows Server 2012 Security Guide, you will need to download the Security Compliance Manager.
Open the Security Compliance Manager , navigate to Guides \ Attachments and then open the “Windows Server 2012 Security Guide.docx
