If your company is one of the thousands in the Defense Industrial Base (DIB), you’re likely familiar with the term CMMC. The Cybersecurity Maturity Model Certification (CMMC) is a unified standard for implementing cybersecurity across the DIB. It’s a framework designed to protect sensitive government information from ever-increasing cyber threats.
Achieving CMMC compliance is not just a regulatory hurdle; it’s a critical component of national security. It shows your commitment to protecting Controlled Unclassified Information (CUI) and ensures your place within the Department of Defense (DoD) supply chain. Without it, you risk losing valuable government contracts.
Navigating the requirements can feel overwhelming, especially for small and medium-sized businesses. That’s why we’ve created this straightforward CMMC compliance checklist. This checklist will help you understand the essential steps, organize your efforts, and move confidently toward certification.
1. Start with Your CMMC Level
The first step in your compliance journey is to determine which CMMC level you need to achieve. The CMMC framework has three levels, each building upon the last with progressively more advanced cybersecurity requirements.
- Level 1 (Foundational): This is the most basic level, requiring companies to perform fundamental cyber hygiene practices. It applies to businesses that handle Federal Contract Information (FCI) but not CUI. Compliance involves 17 security controls from NIST SP 800-171.
- Level 2 (Advanced): This level is for companies that handle CUI. It aligns directly with the 110 security controls outlined in NIST SP 800-171. This is the most common target level for contractors in the DIB.
- Level 3 (Expert): Reserved for companies handling CUI in high-priority programs, Level 3 includes all the controls from Level 2 plus additional, more sophisticated controls from NIST SP 800-172.
Your required level depends on the type of information you handle in your DoD contracts. Review your contracts carefully to identify if you process, store, or transmit FCI or CUI.
2. Perform a Gap Analysis
Once you know your target CMMC level, the next step is to see where you stand. A gap analysis involves comparing your current cybersecurity practices against the specific requirements of your target CMMC level.
This process helps you identify vulnerabilities and areas that need improvement. You can conduct a self-assessment or hire a third-party expert to perform a more thorough evaluation. The goal is to create a detailed list of every control you don’t currently meet. This list will become your action plan for the rest of the compliance process.
4. Control Access to Sensitive Data
A core principle of CMMC is ensuring that only authorized individuals can access sensitive information. This is known as the principle of least privilege. You need to implement strict access controls to manage who can view, modify, or share CUI.
To achieve this, you should:
- Identify and inventory all CUI: Know where your sensitive data is stored, how it’s used, and who has access to it.
- Define user roles and permissions: Create policies that clearly define access rights based on job responsibilities. Not everyone in the company needs access to everything.
- Use access control mechanisms: Implement technical controls like role-based access control (RBAC) to enforce these policies automatically.
- Regularly review access lists: Periodically check who has access to what and revoke permissions for employees who have changed roles or left the company.
5. Use Strong Authentication
Weak passwords are one of the most common entry points for cyberattacks. CMMC requires organizations to enforce strong authentication measures to protect systems and data. This goes beyond just asking employees to create complex passwords.
Your authentication policy should include:
- Password complexity requirements: Mandate a minimum length, a mix of character types (uppercase, lowercase, numbers, symbols), and a password history to prevent reuse.
- Multi-factor authentication (MFA): Implement MFA for all users, especially for remote access and access to systems containing CUI. MFA adds a crucial second layer of security, requiring users to provide two or more verification factors to gain access.
6. Create an Incident Response Plan
It’s not a matter of if a security incident will happen, but when. A well-defined incident response plan is essential for minimizing damage and recovering quickly. Your plan should be a formal, documented process that outlines exactly what to do when a breach occurs.
Key elements of an incident response plan include:
- Roles and responsibilities: Designate an incident response team and clarify each member’s duties.
- Detection and analysis: Detail the procedures for identifying and assessing a security incident.
- Containment and eradication: Outline steps to isolate affected systems and remove the threat.
- Recovery: Plan how to restore normal operations safely.
- Post-incident review: Establish a process for analyzing the incident to prevent future occurrences.
Regularly test your plan with drills and tabletop exercises to ensure everyone knows their role and the plan is effective.
7. Train Your Employees on Cybersecurity
Your employees are your first line of defense. Even the most advanced security technology can be undermined by human error. CMMC compliance requires ongoing security awareness training for all employees.
Training should cover topics such as:
- Recognizing and reporting phishing attempts.
- Understanding the importance of strong passwords and MFA.
- Safely handling CUI.
- Following company security policies and procedures.
Make the training engaging and conduct it regularly to keep cybersecurity top of mind.
