According to the FBI’s annual Internet Crime Complaint Center (IC3), there were 8,47,376 cybercrime complaints in 2021. The total cost of cybercrime in 2121 was $6.9 billion. The complaints have been increasing every year as cybercriminals are using new, more sophisticated methods for malicious attacks. 

To keep one step ahead of cybercrime, the regulatory landscape is also rapidly evolving. Going forward, many industries can expect more data security regulations. But one industry where the tolerance for cybercrime is extremely low is Defense. Due to the sensitive information, a security breach cannot just be quantified in monetary losses – it could be a threat to national security.

This is why, all DoD organizations require that any business entity in their supply chain must comply with a certain level of security standards. The main purpose of introducing CMMC was to have a standardized framework in place for robust cybersecurity. 

In this guide, we will cover everything you need to know about CMMC. 

What Is CMMC?

The Cybersecurity Maturity Model Certification (CMMC) represents a program under the US Department of Defense (DoD) and is applicable to all defense contractors. CMMC was introduced to ensure that all defense contractors meet a certain level of cybersecurity maturity. It is designed to protect the Federal Contract Information (FCI) and Controlled Unclassified Information (CUI) throughout the Defense Industrial Base (DIB). 

CMMC 1.0 was introduced in January 2020. It had 5 levels of certifications that can be loosely described as below.

Level 1 – Foundational cyber hygiene 

Level 2 – Intermediate cyber hygiene

Level 3 – Good cyber hygiene

Level 4 – Proactive cyber hygiene

Level 5 – Advanced/Progressive cyber hygiene 

CMMC has evolved since 2020 but the core idea remains the same. In November 2021, CMMC 2.0 was introduced. CMMC 2.0 has several amendments. The most notable change is that the 5 levels of certification are streamlined into 3 levels. These are as given below. 

Level 1 – Foundational cyber hygiene with basic safeguarding measures expected. This level is expected from DoD contractors that deal with FCI. 

Level 2 – Advanced cyber hygiene aligned with NIST. This level is expected from DoD contractors that deal with CUI.

Level 3 – Expert cyber hygiene aligned with NIST. This level is expected from DoD contractors that deal with the highest priority programs with CUI. 

Apart from the change in the CMMC levels, the new model relies heavily on self-assessments. Thus, DoD contractors can assess and manage their cybersecurity hygiene themselves. Key objectives of CMMC 2.0 include focusing on risk, increasing cost-effectiveness, and ensuring wider accessibility, making compliance easier for both small and large businesses. 

How Does CMMC Relate to NIST?

NIST (National Institute of Standards and Technology) provides the baseline requirements for data protection. CMMC 2.0 incorporates those standards to define a more structured certification model with different levels, third-party audits, and additional requirements specific to DoD contractors. 

CMMC 2.0 requirements are based on the NIST guidelines, more specifically on the NIST Special Publication 800-171

How Long Does CMMC Certification Last?

Once an organization gets certified under CMMC 2.0, the certification is valid for three years. This is to ensure that the certified organization keeps up with the evolving standards as well as the threat landscape.  After three years, the organization will need to go through the assessment and certification process again if they wish to continue working on DoD projects. However, do note that ongoing compliance is necessary during the three-year period.

Who Needs to Comply With CMMC?

CMMC program applies to any individuals or organizations that directly or indirectly work with the U.S. DoD. This includes defense contractors and subcontractors in the DoD supply chain. Since the DoD supply chain is quite extensive, here are examples of some of the industries that need to be compliant with CMMC.

  1. Aerospace: Organizations involved in the development and manufacturing of aircraft, space vehicles, and related equipment and spare parts used by the defense sector.
  2. Defense equipment: Businesses that manufacture defense equipment, weapons, vehicles, hardware, etc. used in defense-related products or offer related services.
  3. IT Services: Companies that provide IT services to DoD organizations including IT infrastructure maintenance and support, cybersecurity, network support, etc.
  4. Research & development: Organizations involved in the R&D of new defense-related technologies or products.
  5. Education: An educational institution that is involved in defense-related research, training, or educational services under DoD contracts.
  6. Professional services: Any organization that provides services such as consulting, engineering, logistics, and administration.

Is CMMC 2.0 Applicable Currently?

All DoD contractors are expected to comply with the appropriate level of CMMC 2.0 by October 2025. (Date subject to change).

Even though CMMC 2.0 compliance is not mandatory at the moment, organizations looking to get themselves certified should start preparing now itself. Due to the extensive nature of the compliance requirements, it’s a good idea to start understanding and implementing the requirements.

Who Issues the CMMC Certification?

An accredited CMMC Third-Party Assessor Organization (C3PAO) assesses whether an organization has implemented the necessary controls as required by the certification level. The C3PAO sends a report to the CMMC Accreditation Body (CMMC-AB) for review. The final decision about issuing the certification lies with CMMC-AB. 

For CMMC 2.0, it is expected that for Level 1 certifications, self-assessment by the organization would be sufficient. Self-assessments would also be sufficient for a subset of Level 2 certifications. For the rest of the Level 2 certifications and all of the Level 3 certifications, third-party assessment would be required. Also, for Level 3 certifications, an assessment carried out by government officials would be required. All these assessments would be triennial to ensure that the compliance is relevant. 

What Is the CMMC Timeline?

  • CMMC 1.0 was introduced on 31st January 2020.
  • CMMC 2.0 was announced in November 2021. However, the announcement was not accompanied by dates for rollout, implementation, and deadlines.
  • NPRM (Notice of Proposed Rulemaking) was announced in May 2023.
  • Currently, the rulemaking is in progress.
  • The expected date by which organizations will need to comply with CMMC 2.0 is October 2025 (subject to change).

What Is the Interim Rule of CMMC?

During the interim period, i.e. till the time CMMC 2.0 would be officially rolled out, organizations can go for CMMC 1.0 certification. Once CMMC 2.0 is codified, the organizations would need to comply with the new rules within the specified deadline.

According to the interim rule of CMMC, all DoD contractors must conduct a cybersecurity self-assessment and assess whether they have implemented all 110 rules as defined in NIST SP 800-171. This assessment needs to be scored – one point for each implemented control and the highest score of 110. Each control not being implemented or implemented only partially would deduct a point. 

When the score is less than 110, DoD contractors need to document a plan to implement the remaining controls in a POA&M (Plan of Action & Milestones). The POA&M would be a living document, constantly updated with details of new controls being implemented and their effectiveness. 

The key elements of POA&M include:

  • Information about the cybersecurity risk due to the absence of a control or the partial implementation of a control
  • Severity of each of the cybersecurity risks identified
  • A plan to manage the cybersecurity risks by eliminating it completely or mitigating it
  • A cost estimate of managing the cybersecurity risk
  • A real-time documentation of the status of each risk

The POA&M should be immediately available upon request from any government authority.    

What Is the Deadline for CMMC Compliance?

While the deadline for CMMC 2.0 implementation has not yet been declared, the time is right for organizations to start preparing for CMMC 2.0. By understanding more about the certification and starting with improving cybersecurity as per the CMMC guidelines, organizations can hope to get certified sooner, once CMMC 2.0 is officially rolled out. Since the eligibility to bid on DoD contracts is tied to CMMC certification, an early certification can make a lot of difference to your chances of winning a bid.

How Much Does CMMC Cost?

The current cost of CMMC 1.0 depends on several factors. The main factors are:

  • Size of the organization
  • The complexity of the organization
  • Level of certification required
  • Fees charged by C3PAO
  • Any costs incurred for implementing the required controls
  • Costs incurred for procuring technology and personnel to implement controls

The fees charged by C3PAO can vary. Hence, it’s a good idea to get quotes from multiple third-party assessors and choose based on the cost as well as the services offered.

Regarding CMMC 2.0, the DoD plans to release a comprehensive cost analysis for each level of CMMC 2.0 as part of rulemaking. However, it is currently anticipated that the costs for CMMC 2.0 will be significantly lower when compared to CMMC 1.0.

CMMC Level 1 certification is based on self-assessment. Assuming that an organization has a good cybersecurity posture, CMMC Level 1 certification will incur a nominal cost. Level 2 and Level 3 certifications would need a more thorough process since these levels are associated with protecting CUI. A rough estimate of the cost of CMMC Level 2 and Level 3 certification suggests that it can range from $18,000 to $400,000, sometimes even more. 

What Are the Benefits of CMMC?

CMMC certification has several benefits summarized below.

  • Improved cybersecurity: Getting CMMC certified involves implementing cybersecurity controls. This improves the cybersecurity posture by establishing cybersecurity best practices and stringent controls. 
  • Competitive edge: Being CMMC certified gives you an advantage over your competitors by positioning you as an organization that takes cybersecurity seriously.
  • Eligibility for DoD contracts: Since most DoD contracts need a CMMC certification, your business is eligible to bid for a contract if you are CMMC certified. 
  • Improved customer confidence: In the current times of rampant cybercrime, CMMC certification helps improve customer trust. 
  • Regulatory compliance: Complying with CMMC can align your organization with the ever-changing regulatory environment. 

CMMC Compliance Checklist

Complying with CMMC requires a systematic approach. Here is a 12-step CMMC checklist to provide a clear path toward CMMC compliance. 

  1. Identify the type of information that needs to be protected: Your required CMMC level depends on the type of government data you handle/will handle. Every defense contractor will need at least Level 1 compliance. If your organization handles CUI, it may require either CMMC Level 2 or Level 3.
  2. Identify the controls to be implemented
  3. Identify the regulatory requirements to address CMMC compliance. Complying with CMMC requires you to understand the program’s objectives and its requirements fully. Comprehensive understanding can help you streamline the certification process.
  4. Create relevant documentation. Some of the Level 2 and all of the Level 3 certification requirements would be validated by a third-party assessor. Hence, just having all compliance practices in place is not enough – you need to prepare and maintain documentation. You will need a System Security Plan (SSP) detailing the use of security controls.
  5. Implement the cybersecurity controls. Upon fully understanding the required controls of CMMC, your team must set up security controls to satisfy these requirements and protect sensitive information. This process includes developing a comprehensive policy list and aligning it with employee practices.
  6. Create POA&M and SSP. In instances where not all NIST SP 800-171 and CMMC controls can be implemented, documented control deficiencies should be outlined in a Plan of Action and Milestones (POA&M), with a specific action plan aimed at rectifying these issues within 180 days. Additionally, a System Security Plan (SSP) must be prepared, delineating the efficacy of each control in enhancing cybersecurity posture; both the POA&M and SSP are crucial documents subject to scrutiny by CMMC auditors.
  7. Evaluate the effectiveness of the implemented controls. Ensuring compliance with CMMC requirements requires repeated risk assessments and bridging gaps in your system. Create checklists that will help your team determine your compliance process.
  8. Monitor and improve controls. Monitoring CMMC controls through tracking key metrics is crucial for understanding long-term trends and identifying areas for improvement. To effectively measure performance and risks, it’s essential to identify relevant Key Performance Indicators (KPIs) and Key Risk Indicators (KRIs) aligned with organizational needs and regulatory obligations.
