CMMC 2.0 Fundamentals: What Every SMB Contractor Needs to Know

If you’re a business working with the U.S. Department of Defense – or even thinking about it – you’ve probably heard the term CMMC tossed around. But what exactly is it, and why does it matter so much? Let’s break it down.

What is CMMC, really?

CMMC stands for Cybersecurity Maturity Model Certification. It’s basically the DoD’s way of making sure everyone in the supply chain takes cybersecurity seriously. It’s about protecting sensitive defense information – like Federal Contract Information (FCI) and Controlled Unclassified Information (CUI) – from hackers, spies, and other threats. In short…

• CMMC is NOT optional if you are competing for DoD contracts.
• CMMC is NOT one-size-fits-all. There are different levels based on what kind of information you handle.

• CMMC is NOT just saying you have strong cybersecurity practices – it’s about proving it.

What’s the point?

Here’s what CMMC aims to do:

• Safeguard FCI and CUI: Make it harder for cybercriminals and foreign actors to steal sensitive defense info.
• Standardize Cybersecurity: Set a common security baseline for ALL contractors, big and small.
• Measure Cybersecurity Maturity: Help companies see where they stand and what they can improve.

It’s not just about checking boxes – it’s about making sure the entire defense supply chain is secure from top to bottom.

The Three Levels of CMMC

The Cybersecurity Maturity Model Certification (CMMC) 2.0 framework is structured into three progressive levels, each designed to enhance the protection of sensitive federal information within the Defense Industrial Base (DIB). These levels build upon one another, aligning with established federal cybersecurity standards to ensure comprehensive security measures are in place.

Level 1: Foundational (Locking Down the Basics)

Level 1 focuses on the protection of Federal Contract Information (FCI), which encompasses information not intended for public release and provided by or generated for the government under contract. This level mandates the implementation of 15 fundamental cybersecurity practices derived from Federal Acquisition Regulation (FAR) 52.204-21. These practices include:

• Utilizing strong, unique passwords

• Implementing firewalls to secure networks

• Regularly updating software to patch vulnerabilities

• Restricting access to authorized users

Organizations are required to conduct an annual self-assessment and submit an affirmation of compliance to the Supplier Performance Risk System (SPRS). This level is suitable for contractors handling FCI but not Controlled Unclassified Information (CUI).

Level 2: Advanced (Getting Serious About Protecting CUI)

This is where things get a bit more serious. Level 2 is tailored for organizations that handle CUI, which refers to information that requires safeguarding or dissemination controls pursuant to and consistent with applicable laws, regulations, and government-wide policies. This level necessitates adherence to 110 security requirements outlined in NIST Special Publication 800-171 Revision 3, which are organized into 14 control families:

1. Access Control (AC)
2. Awareness and Training (AT)
3. Audit and Accountability (AU)
4. Configuration Management (CM)
5. Identification and Authentication (IA)
6. Incident Response (IR)
7. Maintenance (MA)
8. Media Protection (MP)
9. Personnel Security (PS)
10. Physical Protection (PE)
11. Risk Assessment (RA)
12. Security Assessment (CA)
13. System and Communications Protection (SC)
14. System and Information Integrity (SI)

These control families encompass a comprehensive approach to cybersecurity, addressing areas such as access controls, incident response, risk assessment, and system integrity.

Assessment Requirements

Under CMMC 2.0, the assessment requirements for Level 2 vary based on the sensitivity of the CUI and specific contract stipulations:

• Self-Assessment with Annual Affirmation: For certain contracts involving less sensitive CUI, organizations may perform a self-assessment. This involves evaluating their own compliance with the 110 security requirements and submitting an annual affirmation of compliance to the Department of Defense’s Supplier Performance Risk System (SPRS). It’s important to note that the term “affirmation” refers to this annual attestation of compliance.

• Third-Party Assessment by a Certified Third-Party Assessment Organization (C3PAO): For contracts involving more sensitive CUI, a third-party assessment is required. This assessment must be conducted by an authorized C3PAO, which evaluates the organization’s compliance with the 110 security requirements. These assessments are valid for three years, with the requirement for annual affirmations in the interim. Organizations can locate authorized C3PAOs through the Cyber AB Marketplace.

It’s crucial for organizations to understand their specific contract requirements to determine the appropriate assessment path. Regardless of the assessment type, adherence to the 110 security requirements is mandatory for Level 2 compliance.

Level 3: Expert (The Big Leagues)

Level 3 is designed for organizations that handle the most sensitive CUI, particularly in support of critical national security programs. Building upon the requirements of Level 2, Level 3 incorporates additional practices from NIST Special Publication 800-172, which introduces enhanced security measures to protect against APTs. These measures include:

• Enhanced system monitoring and detection capabilities
• Advanced incident response strategies
• Robust access control mechanisms
• Comprehensive security training programs

Organizations must first achieve full compliance with Level 2 requirements before pursuing Level 3 certification. Assessments at this level are conducted exclusively by the Defense Contract Management Agency’s Defense Industrial Base Cybersecurity Assessment Center (DCMA DIBCAC) every three years.

Important Compliance Rules You Should Know

CMMC isn’t operating in a vacuum—it’s deeply integrated with several foundational federal regulations that govern cybersecurity requirements for defense contractors. Understanding these regulations is essential for compliance and maintaining eligibility for Department of Defense (DoD) contracts.

DFARS 252.204-7012: Safeguarding Covered Defense Information and Cyber Incident Reporting

This clause mandates that contractors implement security requirements from NIST SP 800-171 to protect Covered Defense Information (CDI). Additionally, it requires:

• Rapid reporting of cyber incidents to the DoD via the Defense Industrial Base Cybersecurity (DIB CS) portal at https://dibnet.dod.mil.
• Preservation of media and relevant data for at least 90 days post-incident to support potential DoD investigations.
• Flow-down of these requirements to applicable subcontractors.

DFARS 252.204-7021: Cybersecurity Maturity Model Certification Requirements

This clause formally integrates CMMC requirements into DoD contracts. Key stipulations include:

• Contractors must possess a current (not older than three years) CMMC certificate at the level required by the contract and maintain it throughout the contract’s duration.
• Subcontractors must also have the appropriate CMMC certification corresponding to the information they handle.

This clause ensures that cybersecurity standards are consistently applied throughout the supply chain.

FAR 52.204-21: Basic Safeguarding of Covered Contractor Information Systems

Applicable to all federal contractors, this regulation outlines 15 basic safeguarding requirements to protect Federal Contract Information (FCI). These include:

• Limiting system access to authorized users.
• Controlling information posted on publicly accessible systems.
• Implementing timely application of security patches.

Compliance with FAR 52.204-21 is foundational and often serves as the baseline for more advanced cybersecurity requirements.

Bottom line: If these terms are in your contract, it’s time to get moving with CMMC!
