What Is CMMC in Cybersecurity?

The Cybersecurity Maturity Model Certification (CMMC) is a framework designed by the U.S. Department of Defense (DoD) to strengthen cybersecurity across organizations working in the defense industrial base (DIB). 

If your company contracts with the DoD, whether as a supplier, service provider, or subcontractor, you handle sensitive information that could be a target for cyberattacks.

CMMC takes existing cybersecurity standards, like NIST SP 800-171 and NIST SP 800-53, and creates a structured approach to protecting Controlled Unclassified Information (CUI) and Federal Contract Information (FCI). 

The goal is to ensure that every company working with the DoD follows consistent, verifiable security practices to keep critical data safe. If you want to stay competitive in DoD contracts, achieving CMMC compliance is a must.

Purpose of CMMC

If your business works with the Department of Defense (DoD), cybersecurity is a requirement. CMMC ensures that every contractor, supplier, and service provider follows strong, standardized security measures to protect sensitive information. Here’s what it does for you:

  • Keeps Sensitive Data Secure: You handle Controlled Unclassified Information (CUI) and Federal Contract Information (FCI), which makes you a target for cyberattacks. CMMC helps protect that data from being stolen, altered, or exposed.
  • Strengthens Your Cybersecurity: By following CMMC’s requirements, you improve your organization’s ability to detect, prevent, and respond to cyber threats before they cause damage.
  • Creates Consistency Across the Defense Supply Chain: Instead of dealing with varying cybersecurity requirements, CMMC provides a clear, structured framework that DoD contractors must meet. This makes it easier for you to prove your compliance and secure contracts.
  • Secures Your Place in the Industry: DoD contracts increasingly require CMMC compliance. Meeting these standards helps keep you competitive, ensures you can continue working with the DoD, and reduces risks for your business and the entire defense network.

 

By working toward CMMC certification, you’re investing in your company's long-term security and success in the defense industry.

Key Components of CMMC

The CMMC framework consists of three key components:

  1. Maturity Levels: CMMC defines five maturity levels, each representing a different level of cybersecurity capabilities and processes. These levels range from basic cyber hygiene (Level 1) to advanced and proactive cybersecurity practices (Level 5).
  2. Domains: CMMC organizes cybersecurity best practices into 17 domains, such as access control, incident response, and risk management. Each domain contains a set of practices and processes that your organization must implement to achieve a specific maturity level.
  3. Practices and Processes: Within each domain, CMMC defines specific practices and processes that your business must implement to demonstrate their cybersecurity capabilities. These practices and processes are cumulative, meaning that you must implement all practices and processes from lower levels to achieve a higher maturity level.

CMMC Certification Levels

CMMC consists of three certification levels, each representing a different level of cybersecurity maturity and the type of information your organization handles.

Level 1 - Foundational

Level 1 is designed for organizations that handle Federal Contract Information (FCI). To achieve Level 1 certification, you must implement 17 basic security practices, such as access control, incident reporting, and password hygiene. Organizations at this level can self-report their compliance annually.

Level 2 - Advanced

Level 2 is designed for organizations that handle Controlled Unclassified Information (CUI). Compliance at this level involves meeting the 110 security controls specified in NIST SP 800-171. Third-party assessments by Certified Third Party Assessment Organizations (C3PAOs) are required every three years to verify compliance.

Level 3 - Expert

Level 3 applies to organizations working with CUI and facing Advanced Persistent Threats (APTs), often sophisticated, state-sponsored attacks targeting critical defense programs. 

To achieve Level 3 certification, you must comply with both the 110 NIST SP 800-171 security controls and an additional 24 enhanced security controls from NIST SP 800-172. Assessments at this level are conducted by the Defense Industrial Base Cybersecurity Assessment Center (DIBCAC).

 

CMMC Assessment and Certification Process

To achieve CMMC certification, your organization must undergo an assessment by a C3PAO or the DIBCAC, depending on the level of certification required. The assessment process evaluates your organization's cybersecurity practices, controls, and maturity level against the CMMC requirements.

The steps involved in the CMMC assessment and certification process include:

  1. Identifying the appropriate CMMC level for your organization based on the type of information you handle and the contracts you bid on.
  2. Conducting a self-assessment to evaluate your current cybersecurity posture and identify gaps in compliance.
  3. Implementing necessary cybersecurity controls and practices to meet the requirements of the targeted CMMC level.
  4. Engaging a C3PAO or the DIBCAC to conduct the official assessment and verify compliance.
  5. Receiving your CMMC certification upon successful completion of the assessment.

It's important to note that CMMC certification is valid for three years, after which your organization must undergo re-assessment to maintain its certification status. 

So, what does your organization need to become CMMC compliant? 

 

CMMC Compliance Requirements

To achieve CMMC compliance, you need to meet specific requirements across multiple areas, including documentation, policies, technical controls, continuous monitoring, and third-party assessments.

Documentation and Policies

Developing and maintaining comprehensive documentation and policies is a critical part of CMMC compliance. 

You must create and regularly update a System Security Plan (SSP) that outlines your cybersecurity practices, controls, and processes. Additionally, you need to implement policies covering key areas such as access control, incident response, and risk management.

These documents serve as proof of your cybersecurity commitment and provide a clear roadmap for maintaining compliance. They also show assessors that you have a well-structured plan for protecting sensitive information.

Technical Controls

Implementing the right technical controls is another key step in CMMC compliance. Depending on the CMMC level you’re targeting, you will need to put in place various security measures, including:

  • Access control measures, such as multifactor authentication and role-based access control
  • Encryption of sensitive data at rest and in transit
  • Network segmentation and boundary protection
  • Incident detection and response capabilities
  • Vulnerability management and patching processes

These controls help you prevent unauthorized access, detect and respond to security incidents, and maintain the confidentiality, integrity, and availability of sensitive information.

Continuous Monitoring

CMMC compliance isn’t a one-and-done task—it’s an ongoing process. You need to establish a continuous monitoring program to keep your cybersecurity controls effective over time. This includes:

  • Regularly assessing your systems for vulnerabilities
  • Monitoring for security events and anomalies
  • Conducting periodic reviews of your cybersecurity policies and practices

Continuous monitoring helps you identify security gaps before attackers can exploit them and ensures you can adapt to evolving threats while maintaining a strong cybersecurity posture.

Third-Party Assessments

To achieve CMMC certification, you must complete a third-party assessment conducted by either a C3PAO or the DIBCAC, depending on the required certification level. These assessments evaluate whether your cybersecurity controls and practices align with CMMC requirements.

To prepare, you should:

  • Conduct internal audits
  • Gather evidence of compliance
  • Address any identified gaps or deficiencies

Working with an experienced cybersecurity partner can make the assessment process smoother, ensuring you are well-prepared for official evaluation and increasing your chances of achieving certification on the first attempt.

 

How Does CMMC Assessment Work?

The CMMC assessment process is designed to confirm that you have implemented the necessary cybersecurity practices and controls for your targeted CMMC level. Certified Third-Party Assessment Organizations (C3PAOs) play a critical role in this process as the independent entities authorized to conduct these assessments.

When you engage a C3PAO, they will evaluate your compliance with the CMMC framework by reviewing your documentation, policies, and technical controls. The assessment may include:

  • Interviews with key personnel
  • Observations of your cybersecurity practices
  • Testing of security controls

The C3PAO will assess your compliance across the 17 CMMC domains, including access control, incident response, and risk management. They will verify that you have implemented the required practices for your targeted CMMC level and that your cybersecurity posture meets the necessary maturity standards.

Once you successfully complete the assessment, the C3PAO will recommend you for CMMC certification at the appropriate level. This certification demonstrates to the DoD and other stakeholders that you have the necessary cybersecurity measures to protect sensitive information and maintain the integrity of the defense supply chain.

CMMC certification is valid for three years, but you must provide annual affirmations to the DoD, confirming that you continue to meet compliance requirements. This ongoing commitment helps ensure that you remain vigilant and adaptable against evolving cyber threats.
