CMMC (Cybersecurity Maturity Model Certification) 2.0 Level 1 is designed to protectFederal Contract Information (FCI)and consists of17 foundational cybersecurity practices. These practices are directly derived fromFAR 52.204-21(Basic Safeguarding of Covered Contractor Information Systems), which outlines minimum security requirements for contractors handling FCI.

Breakdown of CMMC Level 1 Practices

The17 practicesin Level 1 focus on basic cybersecurity hygiene and fall under the following6 domains:

Access Control (AC)– 4 practices

AC.L1-3.1.1: Limit system access to authorized users

AC.L1-3.1.2: Limit user access to authorized transactions and functions

AC.L1-3.1.20: Verify and control connections to external systems

AC.L1-3.1.22: Control information posted or processed on publicly accessible systems

Identification and Authentication (IA)– 2 practices

Media Protection (MP)– 1 practice

MP.L1-3.8.3: Sanitize media before disposal or reuse

Physical Protection (PE)– 4 practices

PE.L1-3.10.1: Limit physical access to systems containing FCI

PE.L1-3.10.3: Escort visitors and monitor visitor activity

PE.L1-3.10.4: Maintain audit logs of physical access

PE.L1-3.10.5: Control and manage physical access devices

System and Communications Protection (SC)– 2 practices

SC.L1-3.13.5: Implement subnetworks for publicly accessible system components

System and Information Integrity (SI)– 4 practices

SI.L1-3.14.1: Identify, report, and correct system flaws in a timely manner

SI.L1-3.14.2: Provide protection from malicious code at designated locations

SI.L1-3.14.4: Update malicious code protection mechanisms periodically

SI.L1-3.14.5: Perform scans of system components and real-time file scans
