The Cybersecurity Maturity Model Certification (CMMC) is now a requirement for defense contractors handling sensitive information. Understanding CMMC levels and requirements is crucial for maintaining your eligibility to bid on DoW contracts.

What is CMMC?

CMMC is a unified standard for implementing cybersecurity across the Defense Industrial Base (DIB). It was created to protect Controlled Unclassified Information (CUI) and Federal Contract Information (FCI) from increasingly sophisticated cyber threats.

Unlike previous self-attestation approaches, CMMC requires third-party assessment and certification, making it a more rigorous and trustworthy verification of cybersecurity practices.

CMMC 2.0 Levels Explained

CMMC 2.0 streamlined the original five-level model into three levels aligned with existing regulations:

Level 1: Foundational

For: Federal Contract Information (FCI)

  • 17 practices from FAR 52.204-21
  • Annual self-assessment
  • Basic cyber hygiene practices
  • Suitable for contractors handling only FCI

Level 2: Advanced

For: Controlled Unclassified Information (CUI)

  • 110 practices from NIST 800-171
  • Third-party assessment required for select programs
  • Self-assessment for most programs
  • Most common level for defense contractors

Level 3: Expert

For: Critical CUI and highest-priority programs

  • 110+ practices (NIST 800-171 plus subset of 800-172)
  • Government-led assessment required
  • Advanced and persistent threats
  • Applied to select high-value defense programs

Key CMMC Domains

CMMC practices are organized into 14 domains covering comprehensive cybersecurity:

  • Access Control: Limit system access to authorized users and devices
  • Asset Management: Track and manage organizational assets
  • Audit and Accountability: Create and retain system audit logs
  • Configuration Management: Establish and maintain baseline configurations
  • Identification and Authentication: Verify user and device identities
  • Incident Response: Detect, report, and respond to cybersecurity incidents
  • Maintenance: Perform and log system maintenance activities
  • Media Protection: Protect and sanitize information media
  • Personnel Security: Screen and protect against insider threats
  • Physical Protection: Protect facilities and equipment
  • Recovery: Plan for and test system recovery capabilities
  • Risk Management: Identify, assess, and manage security risks
  • Security Assessment: Assess and monitor security controls
  • System and Communications Protection: Monitor and protect communications

CMMC Timeline and Requirements

Current Status

As of 2024, CMMC requirements are being phased into DoD contracts. Key dates include:

  • New contracts will begin including CMMC requirements in solicitations
  • Contractors will need certification before contract award
  • Three-year certification validity for Level 2
  • Annual affirmation required during certification period

Assessment Process

The CMMC assessment process varies by level but generally includes:

  • Pre-assessment preparation and gap analysis
  • Documentation review (System Security Plan, policies, procedures)
  • Technical assessment of implemented controls
  • Interviews with personnel
  • Evidence collection and validation
  • Certification decision and reporting

Preparing for CMMC Certification

Step 1: Conduct a Gap Assessment

Identify where your current security posture falls short of CMMC requirements. This assessment should cover all 14 domains and document existing controls.

Step 2: Develop a Remediation Plan

Create a prioritized plan to address gaps, considering:

  • Risk-based prioritization
  • Budget and resource constraints
  • Timeline to certification
  • Dependencies between controls

Step 3: Implement Controls

Deploy technical controls, update policies and procedures, and train personnel. Ensure all implementations are documented thoroughly.

Step 4: Document Everything

Comprehensive documentation is critical for CMMC assessment. You'll need:

  • System Security Plan (SSP)
  • Policies and procedures for each domain
  • Evidence of control implementation
  • Incident response plans
  • Training records

Common CMMC Challenges

  • Understanding which level applies to your contracts
  • Resource constraints for implementation
  • Maintaining compliance across supply chain
  • Documenting controls in assessment-ready format
  • Keeping up with evolving CMMC requirements
  • Coordinating between IT, security, and business teams
