Mapped to NIST 800-171 Requirement: 3.14.6
CMMC Assessment Objective: SI.L2-3.14.6[c]
What This Control Means
This is the real-world validation checkpoint.
You must demonstrate that:
• Systems requiring updates (servers, endpoints, cloud resources, network devices) have been identified and tracked
• CUI-related systems are specifically included
• System owners know their responsibility for monitoring and applying updates
• Your asset inventory is complete and reflects reality, not theory
Identification must be current, comprehensive, and connected to your vulnerability management efforts.
Why It Matters
If you miss identifying critical systems:
• Known vulnerabilities could go unpatched, exposing CUI
• Some systems may quietly age into risky configurations
• Your compliance posture would suffer during an audit
• Attackers could target overlooked systems as easy entry points
Visibility into update requirements is essential for operational security.
How to Implement It
1. Maintain a Live System Inventory
• List all:
◦ Endpoints (laptops, desktops)
◦ Servers (physical, virtual, cloud)
◦ Network and security appliances
◦ Mobile and remote access devices
2. Identify Update Sources for Each System
• Examples:
◦ Windows Update for Microsoft servers
◦ Vendor repositories for Linux distributions
◦ Firmware and security advisories for network equipment
◦ Patch portals for major SaaS and cloud providers
3. Link Inventory to Risk Management
• Systems handling CUI must be prioritized for updates
• Highlight which systems have patching dependencies or special handling needs
4. Verify Inventory Accuracy Regularly
• Review inventory quarterly or after major deployments
• Use automated discovery tools where possible
Evidence the Assessor Will Look For
• Asset inventory with systems categorized by update requirement
• Lists showing patch sources and update schedules
• Assignment of patching responsibility tied to specific systems
• Documentation confirming CUI systems are included in vulnerability tracking
• Change management records updating system inventory
Common Gaps
• Incomplete system inventories (missing cloud, mobile, or remote endpoints)
• No clear connection between system assets and patching strategies
• Static inventories not updated after system changes
• CUI systems not prioritized or properly flagged
How Cuick Trac Helps
Cuick Trac supports this requirement by:
• Maintaining an up-to-date system inventory linked to CUI and patching requirements
• Tracking and updating asset information automatically or during onboarding processes
• Mapping update sources and timelines to specific systems
• Providing audit-ready evidence that your systems requiring updates are identified and monitored
• Supporting risk prioritization for CUI protection and patch management
With Cuick Trac, system identification isn’t a guessing game—it’s a structured, verified process.
