Introduction
Since my earlier weblog CMMC Readiness was printed in September 2021, the Division of Protection (DoD) has made modifications to this system construction and necessities of the Cybersecurity Maturity Mannequin Certification (CMMC) interim rule first printed in September 2020. CMMC 2.0 was formally launched in November 2021 with the aim of streamlining and bettering CMMC implementation.
On this weblog, I’ll determine the important thing adjustments occurring with CMMC 2.0 and focus on an implementation roadmap to CMMC readiness.
Key adjustments
Key adjustments in CMMC 2.0 embrace:
Maturity Mannequin lowered from 5 compliance ranges to three
Degree 3 – Knowledgeable
Degree 2 – Superior (previous Degree 3)
Degree 1 – Foundational
Improved alignment with Nationwide Institute of Requirements and Expertise (NIST)
NIST SP 800-171
NIST SP 800-172
Practices lowered from 130 to 110 for Degree 2 Certification
Impartial evaluation by C3PAO at Degree 2 – Superior
Self-assessment at Degree 1 – Foundational, restricted at Degree 2 – Superior
Eliminated processes (ML.2.999 Coverage, ML.2.998 Practices, and ML.3.997 Useful resource Plan)

CMMC necessities at Degree 1 and Degree 2 now align with Nationwide Institute of Requirements and Expertise (NIST) Particular Publication (SP) 800-171 – Defending Managed Unclassified Info in Nonfederal Info Programs and Organizations. This alignment needs to be helpful to most DIB organizations since they’ve been topic to FAR 52.204-21 or DFARS 252.204-7012 and will have been self-attesting to NIST SP 800-171 practices whether or not or not it’s the 17 NIST practices required for these dealing with solely FCI or the 110 NIST practices for these handing FCI and CUI. These organizations that took self-attestation severely over time ought to be capable to leverage the work they’ve beforehand carried out to position themselves in a powerful place for CMMC certification.
CMMC 2.0 might have dropped the three Processes (ML.2.999 Coverage, ML.2.998 Practices, and ML.3.997 Useful resource Plan), however that doesn’t get rid of the requirement for formal safety insurance policies and management implementation procedures. CUI safety necessities had been derived partially from NIST Particular Publication 800-53 Safety and Privateness Controls for Federal Info Programs and Organizations (NIST SP 800-53). The tailoring actions addressed in Appendix E of NIST SP 80-171R2 specify that the primary management of every NIST SP 800-53 household (e.g., AC-1, AT-1, PE-1, and so forth.), which prescribe written and managed insurance policies and procedures, are designated as NFO or “anticipated to be routinely glad by nonfederal organizations with out specification”. Which means they’re required as a part of the group’s data safety administration plan and are relevant to the CUI setting. Confer with Appendix E for different NIST SP 800-53 controls which might be designated as NFO and embrace them in your program.
Implementation roadmap
Though there have been welcomed adjustments to the construction of CMMC, my advisable strategy to implementation first offered final September has modified little. The next presents a four-step strategy to get began down the street to CCMC Degree 2 certification.
Schooling
I can’t stress the significance of teaching your self and your group on the CMMC 2.0 necessities. A transparent and full understanding of the statute together with the apply necessities and the certification course of is crucial to reaching and sustaining CMMC certification. This understanding shall be integral to crafting a logical, cost-effective strategy to certification and also will present the data essential to successfully talk together with your govt management group.
Begin your schooling course of by studying the CMMC 2.0 paperwork related to your certification degree discovered at OUSD A&S – Cybersecurity Maturity Mannequin Certification (CMMC) (osd.mil).

CMMC Self-Evaluation Scope – Degree 2 Model 2 December 2021 – Steering on the way to determine and doc the scope of your CMMC setting.
CMMC Evaluation Information – Degree 2 Model 2.0 December 2021 – Evaluation steering for CMMC Degree 2 and the safety of Managed Unclassified Info (CUI).
Outline
The CMMC setting that shall be topic to the certification evaluation have to be formally outlined and documented. The very first thing that the CMMC Third-Celebration Assessor Group (C3PAO) engaged to carry out the Degree 2 certification should do is overview and agree with the CMMC scope offered by the DIB group. If there isn’t any settlement on the scope, the C3PAO can’t proceed with the certification evaluation.
Scope
CMMC setting consists of all CUI-related related property discovered within the group’s enterprise, exterior techniques and providers, and any community transport options. It is best to determine all of the CUI information components which might be current your setting and affiliate them with a number of enterprise processes. This consists of CUI information components offered by the Authorities or a Prime Contractor, in addition to any CUI created by you as a part of the contract execution. Formally doc the CUI information circulate by way of every enterprise course of to visualise the bodily and logical boundaries of the CMMC setting. The knowledge gleaned throughout this course of shall be helpful enter to finish your System Safety Plans (SSPs).
Unsure which information components are CUI? Work straight together with your authorized counsel and DoD enterprise accomplice(s) to achieve a consensus on what information components shall be categorized as CUI. Go to the NARA web site at (Managed Unclassified Info (CUI) | Nationwide Archives) for extra data regarding the varied classes of CUI. Be sure that the classification discussions held by the group and any choices which might be made are documented for posterity. Don’t forget to incorporate CUI information components which might be anticipated to be current below any new agreements.
Determine 2. Excessive-Degree CMMC Evaluation Scope

In the course of the scoping train, you must search for methods to optimize its CMMC footprint by enclaving CUI enterprise processes from non-CUI enterprise processes by way of bodily or logical segmentation. File and database consolidation could also be useful in decreasing the general CMMC footprint, in addition to avoiding dealing with CUI that serves no enterprise objective.
GCC v GCC Excessive
Heads as much as these DIB organizations that make the most of or plan to make the most of cloud-based providers to course of, retailer, or transit CUI. The usage of cloud providers for CUI introduces the GCC vs. GCC Excessive concerns. The GCC setting is appropriate in these cases the place solely Fundamental CUI information components are current. GCC Excessive is required if CUI-Specified or ITAR/EAR designated information components are current. In some cases, prime contractors that utilized GCC Excessive might require their subcontractors to do the identical.
Asset Stock
Asset stock is an necessary and is a vital a part of scoping. The desk under describes the 5 classes of CUI property outlined by CMMC 2.0.
Asset
Description
CUI
Property that course of, retailer, or transmit CUI
Safety Safety
Property that present safety capabilities or providers to the contractor’s CMMC scope.
Contractor Threat Managed
Property that may, however are usually not supposed to course of, retailer, or transmit CUI because of safety controls (insurance policies, requirements, and practices) put in place by the contractor.
Specialised
Particular group of property (authorities property, Web of Issues (IoT), Operational Expertise (OT), Restricted Info Programs, and Take a look at Gear) that will or might not course of, retailer, or transmit CUI.
Out-Of-Scope
Property that can’t course of, retailer, or transit CUI as a result of they’re bodily or logically separated from CUI property.
DIB contractors are required to formally doc all CUI property in an asset stock in addition to of their SSPs. There aren’t any necessities expressed for what data is to be captured within the stock, however I might advocate along with capturing fundamental data (i.e., serial numbers, make, fashions, producer, asset tag id, and placement) you take into account mapping the property to their related enterprise processes and determine asset possession. House owners needs to be given the accountability for overseeing the suitable use and dealing with of the CUI-associated techniques and information all through their helpful lifecycles. An asset administration system is advisable for this exercise, however Microsoft Excel needs to be enough for capturing and sustaining the CUI stock for small to midsize organizations.
Determine 3. Asset Stock
Assess
After getting your asset inventories accomplished and your CMMC scope outlined, it’s time to carry out a niche evaluation to find out your safety posture alignment with CMMC necessities. In case you have been performing your annual self-attestation in opposition to NIST SP 800-171, you’ll be able to leverage this work however make sure you assess with higher rigor. Think about having a CMMC Registered Practitioner from a third-party supplier carry out the evaluation since will present an unbiased opinion of your posture. The outcomes of the hole evaluation needs to be positioned right into a Plan of Motion and Milestones (POAM) the place you’ll assign priorities, duties, options, and due dates for every hole requiring corrective motion.
Remediate
Lastly, use the POAM to drive the organizations remediation efforts in preparation for CMMC certification. Keep in mind that if you happen to contract Third-party providers as a part of remediation (e.g., managed safety providers, cloud providers, and so forth.) these providers turn out to be a part of your CMMC scope. Think about performing a second posture evaluation after remediation efforts are full to make sure you are prepared for the certification evaluation by the C3PAO. CMMC certification is sweet for 3 years, so make sure you implement a governance construction to make sure your program is positioned for recertification when the time comes.
Conclusion
I hope this implementation roadmap gives a profit to you in your CMMC Degree 2 certification journey. Bear in mind, there aren’t any shocking or uncommon safeguards concerned within the course of as CMMC necessities align with trade finest practices for cybersecurity. As with all sturdy data safety program, it’s crucial that you simply totally perceive the IT setting, related enterprise processes, and information property concerned. As we prefer to say in cybersecurity, “you’ll be able to’t defend an asset if you happen to don’t know what it’s or the place it’s at”. Finishing the upfront administrative work corresponding to schooling, scope, and stock pays dividends as you progress towards impartial certification.
