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.

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
