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 PracticesThe17 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 IA.L1-3.5.1: Identify and authenticate system users IA.L1-3.5.2: Use multifactor authentication for local and network access 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.L1-3.13.1: Monitor and control communications at system boundaries 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 Official Reference from CMMC 2.0 DocumentationThe 17 practices forCMMC Level 1are explicitly listed in theCMMC 2.0 Appendices and Assessment Guide for Level 1, as well as in theFAR 52.204-21 requirements.
These practices representbasic safeguarding measuresthat all DoD contractors handlingFCImust implement.
