What is CMMC?

The Cybersecurity Maturity Model Certification (CMMC) is a unified standard for implementing cybersecurity across the Defense Industrial Base (DIB). It's designed to protect sensitive unclassified information that resides on defense contractors' information systems from cyber threats.

Important: Starting in 2025, CMMC certification will be required for all new DoD contracts. Companies without proper certification will be unable to bid on or win DoD contracts.

CMMC 2.0 Levels Explained

Level 1: Foundational

17 Practices | Self-Assessment

Basic cyber hygiene practices
Protects Federal Contract Information (FCI)
Annual self-assessment required
No external assessment needed
Suitable for low-risk contractors

Level 2: Advanced

110 Practices | Third-Party or Self-Assessment

Based on NIST SP 800-171 requirements
Protects Controlled Unclassified Information (CUI)
Triennial third-party assessment for critical programs
Annual self-assessment for select programs
Required for most DoD contractors

Level 3: Expert

110+ Practices | Government Assessment

Based on NIST SP 800-172 requirements
Advanced/persistent threat protection
Government-led assessments
Triennial assessment cycle
For highest priority programs only

CMMC Level 2 Requirements Checklist

Access Control (22 Practices)

Limit system access to authorized users
Control internal system access
Limit data access to authorized users and processes
Employ least privilege principle

Monitor and control remote access

Incident Response (3 Practices)

Establish incident-handling capability
Track and report incidents
Test incident response capability

Audit & Accountability (9 Practices)

Create and retain system audit logs
Protect audit information
Review audit logs regularly
Correlate audit record review and analysis

System & Communications Protection (16 Practices)

Monitor and control communications at boundaries
Implement subnetworks for publicly accessible systems
Employ cryptographic mechanisms
Control and monitor use of mobile code

Common CMMC Challenges & Solutions

Technical Challenges

Legacy Systems: Upgrade or isolate systems that can't meet requirements
Multi-Factor Authentication: Implement MFA across all systems accessing CUI
Encryption: Deploy FIPS-validated encryption for data at rest and in transit
Logging & Monitoring: Centralize log collection and implement SIEM solutions
Network Segmentation: Isolate CUI environments from corporate networks

Organizational Challenges

Culture Change: Build security awareness through regular training
Resource Allocation: Dedicate personnel to CMMC compliance efforts
Supply Chain: Flow down requirements to subcontractors
Documentation: Maintain comprehensive policies and procedures
Continuous Monitoring: Establish ongoing compliance verification

Financial Challenges

Budget Planning: Include CMMC costs in contract pricing
ROI Justification: Position as business enabler, not just compliance
Phased Approach: Prioritize critical controls and high-risk areas
Shared Services: Consider managed security service providers
Government Resources: Leverage free tools and guidance from DoD

Frequently Asked Questions

When will CMMC be required for DoD contracts?

CMMC requirements are being phased in starting in 2024, with full implementation expected by 2025. Check specific solicitations for requirements.

Can I self-assess for Level 2?

Some Level 2 programs allow annual self-assessments, but critical programs require third-party C3PAO assessments every three years.

How long is CMMC certification valid?

CMMC certifications are valid for three years, with annual affirmations required to maintain certification status.

Do subcontractors need CMMC certification?

Yes, if subcontractors handle CUI or FCI, they must meet the same CMMC level requirements as the prime contractor.

What's the difference between CMMC 1.0 and 2.0?

CMMC 2.0 simplified the model from 5 levels to 3, removed unique practices, and aligned directly with NIST standards.
