Key Takeaways
- CMMC Level 1 focuses on protecting Federal Contract Information through 15 mandatory cybersecurity practices based on FAR clause 52.204-21.
- Certification requires full implementation of these safeguards, an annual self-assessment, and submission of compliance affirmation in the Department of Defense’s Supplier Performance Risk System.
- Meeting Level 1 requirements is essential for contractors handling FCI and serves as a critical gateway for eligibility in numerous DoD contracts.
Introduction
The Department of Defense (DoD) has introduced the Cybersecurity Maturity Model Certification (CMMC) to strengthen the cybersecurity posture of its contractors. CMMC Level 1 represents the foundational step in this framework, targeting contractors who handle Federal Contract Information (FCI) but not Controlled Unclassified Information (CUI). Understanding the detailed practices and compliance steps required at this level is crucial for contractors aiming to secure or maintain eligibility for many defense contracts. This article explores the essentials of CMMC Level 1 requirements, the compliance process, and the broader implications for contractors within the defense industrial base.

What Is CMMC Level 1 and Who Does It Apply To?
CMMC Level 1 certification targets organizations that process, store, or transmit FCI during the execution of DoD contracts. FCI consists of sensitive information provided by or generated for the Government but not intended for public release. Significantly, this level does not cover Controlled Unclassified Information (CUI), which requires adherence to higher CMMC levels.
This foundational level is geared toward contractors and subcontractors who handle FCI only, establishing baseline cybersecurity measures to safeguard government data.
The 15 Essential Safeguarding Practices of Level 1
At the heart of Level 1 compliance lie 15 essential cybersecurity practices derived from the Federal Acquisition Regulation (FAR) clause 52.204-21. These practices provide a straightforward yet effective set of controls intended to secure FCI within contractor information systems.
The practices are grouped into six key categories:
Access Control
- Restrict system access solely to authorized users.
- Ensure only authorized devices can connect to systems.
- Control and verify access to system software and resources.
Identification and Authentication
- Authenticate users, processes, or devices prior to granting system access.
Media Protection
- Sanitize or destroy media that contains FCI before disposal or reuse.
- Safeguard FCI on both digital and physical media during storage and transport.
Physical Protection
- Limit physical access to information systems, associated hardware, and the operating environment to authorized personnel only.
System and Communications Protection
- Monitor and regulate communications at external system boundaries and key internal network points.
- Implement subnetworks to isolate publicly accessible system components.
System and Information Integrity
- Detect, report, and correct system vulnerabilities and flaws.
- Defend information systems against malicious software.
- Maintain current virus protection with timely updates.
- Conduct periodic scans on information systems and real-time scans on files during download or execution.
It is important to note that partial compliance or submission of Plans of Action and Milestones (POA&Ms) is not acceptable at Level 1; contractors must fully implement all 15 practices to meet certification requirements.
"Full implementation of these foundational practices forms the bedrock for protecting Federal Contract Information and ensures contractors meet the minimum security posture mandated by the DoD."
Navigating Assessment and Affirmation Procedures
Unlike higher levels of CMMC, Level 1 certification does not require third-party assessments. Instead, contractors must conduct an internal self-assessment annually. The results and a formal affirmation of compliance must then be submitted to the DoD’s Supplier Performance Risk System (SPRS) or its successor platform.
Failure to perform and submit the annual self-assessment and affirmation leads to expiration of Level 1 certification, which directly impacts a contractor’s ability to secure relevant DoD contracts.
To understand the full CMMC assessment process and how to maintain certification is highly recommended to ensure you meet all ongoing requirements.
Ensuring Cybersecurity Across the Supply Chain
Prime contractors certified at Level 1 must ensure that their subcontractors handling FCI comply with the same Level 1 requirements. This flow-down obligation guarantees cybersecurity consistency throughout the entire supply chain, maintaining the integrity of DoD information across all contract participants.

Why Level 1 Compliance Matters Strategically
While Level 1 represents the most basic tier in the CMMC hierarchy, it plays a pivotal role in setting a cybersecurity baseline within the Defense Industrial Base (DIB). Many small and mid-size contractors start here, ensuring eligibility for a wide scope of DoD contracts. Implementing these controls not only helps protect sensitive government data but also paves the way for future advancement to higher certification levels, which become necessary when handling CUI.
Conclusion
CMMC Level 1 stands as a foundational cybersecurity safeguard for contractors who handle Federal Contract Information. With 15 critical practices outlined by FAR clause 52.204-21, strict full implementation is mandatory, complemented by an annual self-assessment and affirmation process. As CMMC continues to shape the cybersecurity requirements for DoD acquisitions, achieving and maintaining Level 1 certification is essential for contractors aiming to compete and comply in the defense contracting arena.
