Automate the .NET Framework STIG

Applying the .NET STIG is definitely not straightforward. For many administrators it can take hours to fully implement on a single system. This script applies the required registry changes and modifies the machine.config file to implement FIPS and other controls as required.

Notes:

This script can not and will not ever get the .NET stig to 100% compliance. Right now, as is, it stands to complete roughly 75% of the checks and does go back and complete the applicable checks on all previous .NET versions.

Manual intervention is required for any .NET application or IIS Site.

Requirements:

• Windows 7, Windows Server 2008 or newer
• Testing in your environment before running on production systems.

STIGS/SRGs Applied:

• Microsoft .Net Framework 4 V1R9

Sources:

• Add from one XML data to another existing XML file
• Caspol.exe (Code Access Security Policy Tool)
• Microsoft .NET Framework Documentation
• PowerShell $PSScriptRoot
• PowerShell: Run command from script's directory
• Powershell XML importnode from different file
