Shared Responsibility Matrix
Cloud Service Provider's Shared Responsibility Matrix
In today's rapidly evolving digital landscape, safeguarding controlled unclassified information (CUI) within non-federal systems and organizations is more critical than ever. For Department of Defense subcontractors and manufacturers, adhering to the National Institute of Standards and Technology's Special Publication 800 171 Revision 2 is not just a recommendation—it's a requirement.
If you are wrapping up your CMMC Level 2 preparations, here are some pointers to be sure you did not miss any important items.
Let's talk about any Cloud Service Providers that may process, store, or transmit CUI. An example of this would be Microsoft Office 365. If you are using Microsoft Office 365 for email and you transmit CUI in your email, or store CUI using OneDrive, Teams, or SharePoint you will need to perform the due diligence in validating that your Microsoft Licenses is part of the FedRAMP Moderate certification. This would apply to any Cloud offering that you process, store, or transmit CUI.
An essential part of FedRAMP certification is your cloud service provider should supply you with a shared responsibility matrix. The shared responsibility matrix is a list of the NIST SP 800 171 Rev 2 controls that you will need to maintain and prove that you are adhering to them.
