NIST Cybersecurity Framework: Tools and References from Microsoft - Protect Function

Sergey Tsygalnitsky

The National Institute of Standards and Technology (NIST) Cybersecurity Framework provides voluntary guidance – a set of industry standards and best practices – for reducing cybersecurity risks to critical infrastructure. Organizations that want to utilize the framework may find the task daunting at first, but it is helpful to remember that many of the subcategories in the framework can be accomplished with products and technologies they are already using.

Countless organizations around the globe rely on Microsoft technology to achieve their objectives. Understanding how Microsoft products and technologies relate to the NIST Cybersecurity Framework can help customers make significant progress in implementing it. After having several customers and partners ask me about utilizing the NIST Cybersecurity Framework, I’ve begun mapping Microsoft products and architectural references to subcategories of the Framework.

This post addresses the Protect function. Read my post about the Identify function mapping, and look for posts over the next few weeks covering the Detect, Respond, and Recover functions.

Protect function mapping

About the mapping

In the tables below, I’ve mapped Microsoft products and architectural references to subcategories of the Protect function in the Framework. The resources listed reflect product information and how-to documentation, and do not include Microsoft service offerings (for example, Premier or MCS). Where I’ve left subcategories blank, the activity should be covered by the implementing organization utilizing internal resources or third parties. For Microsoft partners, that white space is the opportunity to step in and provide much needed services.

If you have a resource to add to the list below, share your feedback with me in the Enterprise Security + Mobility Partners Yammer group.
