Security Note:
Some legacy CNC/PLC systems run older/embedded OS versions. Mitigation relies heavily on network segmentation (VLANs 50-80) and isolation.

Security Stack
CMMC Compliance Progress
Top Compliance Risks
-
Supply Chain:
Subcontractors may not meet CMMC flow-down requirements.
-
Legacy Mfg Equipment:
Cannot install agents on embedded OS CNC machines.
-
Incident Response:
Testing frequency gap; IR plan needs more tabletop validation.

Instructor Guide
Use this case study for the following learning objectives:
1. CMMC Scoping
Have students identify which VLANs constitute the "CUI Assessment Scope" and which are out of scope. Discuss why the Guest Network (VLAN 90) is treated differently.
2. Gap Analysis
Using the asset inventory, ask students to map specific NIST 800-171 controls to the available tools (e.g., Control 3.14.1 to Splunk/Cisco Firepower).
3. Incident Response
Run a tabletop exercise based on "Incident 2" (USB in manufacturing). How does the lack of agents on OT devices complicate this?
4. Cloud Governance
Discuss the implications of moving CUI to Azure Government. What changes in the Shared Responsibility Model?
