    Understanding CMMC

    What is CMMC?

    The Cybersecurity Maturity Model Certification, or CMMC, is a unified standard designed to assess and enhance the cybersecurity posture of organizations that engage with the U.S. Department of Defense (DoD). This framework aims to standardize cybersecurity practices across the defense industrial base (DIB) and ensure that contractors and subcontractors meet the necessary cybersecurity requirements.

    The original CMMC framework was announce in 2019. It featured five levels of maturity (1-5) with increasing requirements as the levels progressed. In November 2021, the Department of Defense released CMMC 2.0. This streamlined the compliance model into three tiers (Levels 1, 2 and 3).

    Why is CMMC Necessary?

    The need for CMMC arises from the ever-increasing cyber threats organizations face, particularly those dealing with sensitive government data and contracts. In an era of data breaches and cyberattacks, CMMC provides a robust defense mechanism to safeguard sensitive information and ensure the integrity of the defense supply chain.

    CMMC Framework

    Overview of CMMC Levels

    CMMC 2.0 comprises three maturity levels. CMMC Level 1 is the most basic level. It comprises 17 practices from NIST 800-171. Companies that meet Level 1 compliance are required to submit an annual self assessment. Bright Defense can assist with the 17 controls and the assessment process.

    CMMC 2.0. Level 2 is aligned with NIST SP800-171. It comprises 110 controls. A third-party assessments are required every three years for critical national security data. Annual self assessments will also be required.

    CMMC 2.0 Level 3 is the most stringent. There are over 110 requirements based on NIST SP 800-171 and 800-172. Government-led assessments will be required every three years for Level 3 contractors. 

    CMMC 2.0 is currently in the rule-making process. Companies that want to do business with the defense industrial base must meet CMMC 2.0 once the rules go into effect. This is estimated to take place in 2024.

    CMMC Assessment Process

    Preparing for a CMMC Assessment

    Preparation is key to a successful CMMC assessment. It involves understanding the requirements of your chosen CMMC level, identifying potential gaps in your cybersecurity practices, and putting corrective measures in place. Bright Defense specializes in assisting organizations with this preparatory phase.

    Choosing the Right Assessment Level

    Selecting the appropriate CMMC level is crucial. Businesses should assess their current cybersecurity practices, the nature of their work with the DoD, and the level of CUI they handle to determine the most suitable level. Bright Defense can provide guidance in this decision-making process.

    Selecting an Accredited Assessor

    Certified Third-Party Assessor Organizations (C3PAOs) must conduct CMMC assessments. Choosing the right assessor is essential to ensure a fair and thorough evaluation. Bright Defense can help you connect with reputable assessors experienced in CMMC assessments.

    CMMC Compliance Steps

    Gap Analysis

    Conducting a gap analysis is the first step towards CMMC compliance. This process involves identifying areas where your organization’s current cybersecurity practices fall short of the requirements outlined in the chosen CMMC level. Bright Defense’s expertise in this phase can significantly streamline the process.


    Once gaps are identified, organizations must take corrective action to address vulnerabilities and shortcomings. Remediation involves implementing cybersecurity best practices, updating policies and procedures, and enhancing security controls to meet CMMC requirements.


    Documentation is a crucial aspect of CMMC compliance. Organizations must maintain accurate records of their cybersecurity practices and actions taken during the gap analysis and remediation phases. These records serve as evidence during the assessment process.

    The Assessment Process

    During a CMMC assessment, certified assessors evaluate an organization’s cybersecurity practices against the selected CMMC level. This involves reviewing documentation, conducting interviews, and assessing the effectiveness of security controls. The assessment process ensures that organizations meet the required standards.

    Handling Assessment Findings

    Assessment findings can result in various outcomes, ranging from full compliance to non-compliance with the chosen CMMC level. It is essential to address any non-compliance issues promptly, implementing corrective measures and documenting the changes made.

    Maintaining CMMC Compliance

    Continuous Monitoring

    CMMC compliance is not a one-time achievement; it requires continuous monitoring and improvement. Organizations should establish processes for ongoing cybersecurity maintenance and regularly update their practices to stay aligned with evolving threats and CMMC requirements. Bright Defense offers continuous cybersecurity compliance services to support this critical aspect of compliance.

    Navigating Changes in CMMC

    The cybersecurity landscape is dynamic, and CMMC requirements may evolve over time. Organizations must stay informed about changes and updates to the CMMC framework to ensure continued compliance. This involves ongoing training, assessments, and adjustments to cybersecurity practices.

    CMMC vs. NIST SP 800-171: Understanding the Key Differences

    Before the introduction of the Cybersecurity Maturity Model Certification (CMMC), the National Institute of Standards and Technology (NIST) Special Publication 800-171 was the primary framework for safeguarding Controlled Unclassified Information (CUI). While CMMC builds upon the foundation of NIST SP 800-171, it introduces several critical differences and improvements that organizations must be aware of when transitioning to this new standard.

    Certification vs. Self-Assessment:

    • NIST SP 800-171: Under NIST SP 800-171, organizations were typically responsible for self-assessing their compliance with the framework. They could create a System Security Plan (SSP) and a Plan of Action and Milestones (POA&M) to document their progress and address identified deficiencies.
    • CMMC: CMMC introduces a certification process that involves third-party assessments. Organizations must undergo assessments conducted by Certified Third-Party Assessor Organizations (C3PAOs) to achieve certification at one of the three CMMC maturity levels. This shift from self-assessment to third-party certification adds a layer of objectivity and rigor to the evaluation process.

    Maturity Levels:

    • NIST SP 800-171: NIST SP 800-171 provides a set of security requirements but does not prescribe different maturity levels. Organizations were expected to implement all specified controls to safeguard CUI.
    • CMMC: CMMC introduces three maturity levels, each with its own security practices and processes. Organizations can select the CMMC level that aligns with their specific needs and the sensitivity of the data they handle. This tiered approach allows for a more tailored approach to cybersecurity.

    Progressive Requirements:

    • NIST SP 800-171: NIST SP 800-171 provides a static set of security controls that organizations must implement. Compliance was largely binary – either a control was in place, or it was not.
    • CMMC: CMMC’s maturity levels are progressive, with each level building upon the requirements of the previous one. This approach encourages organizations to improve their cybersecurity posture and adapt to evolving threats continuously. Achieving a higher CMMC level reflects greater cybersecurity maturity and capability.

    Assessment Scope:

    • NIST SP 800-171: Organizations could focus solely on the protection of CUI when implementing NIST SP 800-171 controls.
    • CMMC: CMMC considers a broader range of security practices, including protection against advanced persistent threats (APTs) and ensuring the overall security of the defense supply chain. This expanded scope addresses the evolving cyber landscape and aligns with the DoD’s commitment to enhancing cybersecurity across its contractor base.

    Ongoing Monitoring:

    • NIST SP 800-171: While NIST SP 800-171 encouraged organizations to continuously monitor their security controls, it did not specify the frequency or extent of monitoring activities.
    • CMMC: CMMC emphasizes the importance of continuous monitoring and adaptation. Organizations must maintain ongoing security practices and stay vigilant against emerging threats. This focus on continuous improvement is integral to CMMC compliance.

    In summary, while NIST SP 800-171 laid the foundation for cybersecurity practices in the defense industry, CMMC takes a more comprehensive and progressive approach. Introducing third-party certification, maturity levels, and an expanded assessment scope sets CMMC apart as a more robust framework for safeguarding sensitive information and enhancing cybersecurity maturity within the defense industrial base. Organizations transitioning to CMMC should carefully evaluate these differences to ensure a successful and compliant migration.
