SI.L2-3.14.5[c]: Prove That Malware Protections Are Active and Defending Your CUI Systems

Mapped to NIST 800-171 Requirement: 3.14.5
CMMC Assessment Objective: SI.L2-3.14.5[c]

What This Control Means
This is the operational implementation checkpoint.
You must show that:
• Antivirus, antimalware, EDR, or endpoint protection platforms are installed, configured, and operating on all CUI-related systems
• Real-time malware detection and alerting are enabled and active
• Threat detection coverage includes workstations, servers, cloud environments, and mobile devices where CUI is handled
It’s not enough to have a license—you must demonstrate live, working protections.

Why It Matters
Without active malware protection:
• Malware could compromise CUI without detection
• Phishing or ransomware attacks could succeed unchallenged
• Endpoint security gaps could undermine your entire compliance and cybersecurity posture
• CUI integrity and confidentiality would be at risk
Malware protection isn’t optional—it’s a real-time, non-stop requirement.

How to Implement It
1. Deploy Malware Protection Across All CUI Systems
• Laptops, desktops, servers (on-prem and cloud)
• Mobile devices used for accessing or storing CUI
• Remote access endpoints
• Email gateways and cloud storage
2. Validate Live Protection
• Confirm:
◦ Real-time scanning is active
◦ Threat definitions are updated automatically
◦ Alerts are configured for malware detections
3. Review Monitoring Dashboards
• Verify active threat detection coverage and recent detection events
• Ensure systems without active protection are flagged for remediation
4. Include Malware Protections in System Onboarding
• Ensure new systems are enrolled into endpoint protection before deployment into production environments

Evidence the Assessor Will Look For
• Screenshots of active endpoint protection agents on devices
• Live dashboards from antivirus, EDR, or SIEM platforms
• Logs showing malware scans, detections, and resolutions
• System onboarding checklists confirming malware protection installation
• Remediation records for malware incidents

Common Gaps
• Antivirus installed but real-time protection disabled
• Some systems (e.g., servers, remote endpoints) missing malware protection
• Cloud-based workloads (e.g., AWS EC2, Azure VMs) left unprotected
• Monitoring dashboards present but inactive or ignored

How Cuick Trac Helps
Cuick Trac supports this requirement by:
• Verifying malware protection agent deployment across all systems handling CUI
• Monitoring endpoint protection health, update status, and detection activity
• Alerting if malware protection is disabled or missing from critical systems
• Logging malware events and linking them to incident response processes
• Providing auditors with live evidence of malware protection enforcement
With Cuick Trac, your CUI-related systems stay protected, visible, and continuously secured.

Final CTA
Malware doesn’t rest—and neither should your defenses.
Schedule a Cuick Trac demo to validate your malware protections and keep your CUI environment secure and compliant.
