After a long and anxious wait, the Department of Defense (DoD) eventually published the CMMC Final Rule on October 15, 2024. The newly issued regulation will take effect on December 16, 2024, although full operation is expected to commence from around mid-2025.  

According to the CMMC Final Rule, all organizations and corporations that store or process CUI must achieve full CMMC compliance or risk a number of specified penalties. If you’re a DoD contractor, it’s imperative to conduct a comprehensive CMMC audit and master the procedure required to attain regulatory compliance.  

This post shall explore the CMMC assessment handbook and its relevance to DIBs. But first, let’s begin by understanding what CMMC compliance entails and its significance for DoD contractors.   

What Is CMMC? 

CMMC, short for Cybersecurity Maturity Model Certification, is a Department of Defense program introduced to safeguard the defense industrial base (DIB) from unintended leakage of sensitive security information.  

The defense industrial base is a global network of companies, organizations, and facilities that provide the U.S. government with products and services required for defense purposes. It’s also sometimes known as the defense industrial and technological base and encompasses both public and private sector corporations.  

DIBs play a pivotal role in the design, development, production, and maintenance of military weapons and related systems. The entities mostly handle a category of federally designated critical information known as controlled unclassified information (CUI).  

CUI isn’t necessarily classified information. However, it bears a considerable degree of sensitivity and privacy, necessitating its controlled storage and release.  

Now, the Department of Defense requires all DIBs to handle CUIs within a CMMC framework. The implication is that all aspiring DoD contractors must strictly adhere to CMMC’s Final Rule, a process that requires rigorous assessment of an organization’s cybersecurity infrastructure.  

Fortunately, you don’t need to be a tech geek to evaluate your CMMC compliance levels. You can always enlist professional assistance and go about your routines, as the third-party agency lets you ace all CMMC-related requirements.   

What Is CMMC’s Relevance to DIB Organizations? 

The Department of Defense had existing information security protocols for its contractors before unveiling the CMMC Final Rule. However, the agency observed that cybersecurity threats were becoming increasingly rampant and complex. These threats targeted all entities concerned with the design and delivery of military products and services, including those considered farther below the DoD’s supply chain.  

In light of the increasing cyber-attacks, the DoD formulated a more robust cybersecurity template to protect controlled unclassified information. Under the Final Rule, CUI handlers must meet certain CMMC levels to be deemed compliant.  

It’s worth noting that CUI doesn’t only pertain to military weaponry. The information could also relate to federal systems’ health, technology, finance, and general privacy.  

CMMC is based on existing cybersecurity protocols, particularly the National Institute of Standards and Technology (NIST) Special Publications 800-171 and 800-53. 

What Is The CAP Handbook? 

The CMMC Assessment Process (CAP) handbook is a practical guide spelling out the strict procedures required by third-party assessor organizations (C3PAOs), as outlined in the CMMC framework. The handbook, the brainchild of the CMMC Accreditation Body (CMMC AB), has been extensively reviewed and officially endorsed by the Department of Defense.  

According to the CAP handbook, CUI handlers must satisfy all specified CMMC levels during scheduled C3PAO assessments. That entails conducting rigorous CMMC audits to uncover and seal potential CUI loopholes.  

Although customized for use by C3PAOs, the CAP has proven instrumental for Certified CMMC Professionals (CCPs) and Certified CMMC Assessors (CCAs). 

What Is The Role Of C3PAOs? 

Third-party assessor organizations are a critical component of the CMMC assessment process. Their primary responsibility is to evaluate organizations’ existing cybersecurity protocols to ensure they meet the DoD’s CMMC standards.  

Not every company can become a C3PAO. To attain this prestigious title, an organization must be certified by the CMMC Accreditation Body.  

The accreditation process is more grueling than you can imagine. It requires, among other prerequisites, demonstrating robust IT systems.  

What Are The Phases Of CAP? 

The CMMC Assessment Process handbook is organized into four distinct phases, namely; 

• Phase 1 – Planning and preparation 
• Phase 2 – Conducting assessment 
• Phase 3 – Reporting the assessment results. 
• Phase 4 – An optional phase that involves closing out a Plan of Action and Milestones (POA&Ms) and Assessment 

Collectively, the four CAP phases ensure each CMMC assessment achieves the highest possible scores in accuracy and fidelity. They also maximize consistency, ensuring the CMMC audits undertaken by different C3PAOs yield consistent and verifiable results.  

Further, the four CAP phases help improve the cybersecurity posture of DIB entities.  

The 4 CAP Phases Explained 

Planning and Preparing for the Assessment 

The first CAP phase also happens to be the most extensive.  

First, an Organization Seeking Compliance (OSC) sends a CMMC assessment request to a C3PAO. OSCs, as the name suggests, are DIB companies that wish to have their cybersecurity architectures audited in line with the DoD’s CMMC regulations.  

The initial engagement typically entails reaching out to prospective C3PAOs on the online CMMC marketplace maintained by the CMMC Accreditation Body – The Cyber AB. While all listed C3PAOs are qualified and authorized to conduct CMMC audits, the Cyber AB may occasionally require you to consider specific companies.  

After making initial contact, the OSC and C3PAO proceeded to establish the terms of engagement. The exact approach may vary, although a critical component entails assessing if an OSC is already utilizing external Cloud Service Providers (CSPs). Other essential areas the C3PAO may evaluate here include the OSC’s online data storage systems and compliance status with the DFARS 252.204-7012 requirements.  

If the OSC and C3PAO are on the same page, the next step is to discuss contractual arrangements. This mostly includes drafting a structure for the execution of the assessment.  

Once the contractual arrangements are in place, the C3PAO will prepare relevant assessment templates. These include but are not limited to pre-assessment templates, virtual assessment evidence forms, C3PAO-assessor conflict of interest attestation, and CMMC assessment results. 

In the next step of the CAP Phase 1, the C3PAO and OSC ascertain the defined assessment conditions. It’s at this point that the OSC formally green-lights the C3PAO to assess their cybersecurity protocols as per the CMMC framework.  

Once authorized, the C3PAO evaluates the OSC’s organizational size, applicable contractual requirements, and expected logistical pitfalls. This is necessary to predict the CMMC assessment scope. The details are filled out in a pre-assessment plan.  

Finally, the C3PAO and OSC complete the first CAP phase by verifying their readiness to conduct the CMMC audit. At this stage, both parties can review the deliverables to determine if they’re still on the same page.  

Conducting the Assessment 

While the CAP’s Phase 1 is extensive, it’s Phase 2 that actually determines if an OSC receives CMMC certification or not. Phase 2 entails the C3PAO evaluating the OSC’s level of compliance with the CMMC protocols.  

Ideally, the C3PAO will review your company’s IT and cyber documentation to determine how well they adhere to the DoD’s CUI standards. Further, the assessor may conduct staff interviews and perform experimental tests to uncover potential gaps and vulnerabilities.  

Note that the compliance assessment will depend on the CMMC levels for which you wish to be evaluated.  

The CAP Phase 2 also outlines how C3PAOs should assess CSPs lacking FedRAMP Moderate ATOs. As this will determine the overall score, it’s prudent for OSCs to understand their in-scope CSP relationships before undertaking CMMC compliance audits.  

At the end of Phase 2, the C3PAO will prepare preliminary findings of compliance or non-compliance. Such findings would later be aggregated when calculating the overall score, which should be at least 80% (88/110) to be deemed CMMC compliant. Currently, the OSC is ready to receive conditional level 2 CMMC compliance certification.  

Reporting the Assessment Results 

In CAP’s Phase 3, the C3PAO will share the assessment results with the OSC to reveal whether they meet the minimum requirements for CMMC certification.  

There are three possible reports in the assessment results forms, namely; 

• Met the CMMC requirements unconditionally 
• Met the requirements conditionally 
• Fell short of the minimum requirements 

The first score automatically qualifies you for the fourth and final CAP phase. Meanwhile, the second score necessitates Plans of Action & Milestones (POA&Ms), while the third score implies you still have considerable work to do to achieve CMMC compliance. 

Closing Out of POA&Ms 

This is an optional step that’s only necessary if your organization received CMMC Level 2 certification during the scoring stage. The Department of Defense allows up to 180 days to close out all POA&Ms.  

After 180 days, a C3POA will award your company the final score depending on the outcome of the POA&Ms. Failure to meet the requirements will result in the conditional certification being withdrawn while satisfying the requirements will result in you being awarded an unconditional compliance status. 

Currently, the consequences of failing the POA&Ms assessment are unclear for existing DoB contractors. Your best bet is to stay updated on CMMC protocols and ensure you ace the assessment by Phase 2. 

Summary 

Understanding the CMMC assessment process is more important than simply obtaining regulatory compliance.  

Adhering to the DoD’s requirements on safe CUI handling maximizes your chances of securing lucrative federal tenders while minimizing the risks of having existing contracts terminated. Besides, it allows you to undertake significant data audits in your organization and improve your cybersecurity posture.  

By attaining CMMC certification and undertaking routine compliance assessments, you can ensure long-term protection from unforeseen data breaches. Note that such breaches, if they were to occur, could result in massive financial losses, reputational damage, and (in certain instances) costly lawsuits.
