CMMC Level 2 for Machine Shops
The Plain-English Compliance Handbook for CNC Manufacturing
CMMC Level 2 doesn't have to be a cybersecurity project you hand over to an expensive consultant.
If you own or manage a CNC machine shop, precision manufacturing company, fabrication business, or other small defense supplier handling Controlled Unclassified Information (CUI), this practical handbook shows you how to turn CMMC and NIST SP 800-171 requirements into concrete actions you can actually implement on your shop floor.
Instead of generic cybersecurity theory, this book translates compliance into the real-world environment of CNC machines, legacy controllers, CAD files, G-code, USB drives, engineering drawings, office networks, shop-floor networks, MSPs, subcontractors, and defense-contract data.
Inside, you'll learn how to:
Understand what CMMC Level 2 means for your specific machine shop
Determine whether FCI or CUI is actually entering your environment
Define your CMMC compliance boundary before wasting money securing systems that don't need to be in scope
Separate your office network from your CNC shop-floor network
Deal with legacy Windows XP and Windows 7 machine controllers that cannot simply be patched
Build safer G-code and USB transfer workflows
Map CUI from RFQ email through programming, machining, inspection, and shipment
Identify CUI Assets, Security Protection Assets, Specialized Assets, and other systems in your environment
Work through the 110 NIST SP 800-171 security requirements in practical shop-floor language
Build your System Security Plan (SSP)
Create and manage your POA&M
Understand SPRS self-assessment and scoring
Prepare for a C3PAO assessment
Identify common assessment findings before an assessor finds them
Flow CMMC requirements down to suppliers and subcontractors
Establish an ongoing compliance program instead of treating CMMC as a one-time project
PLUS: Practical Working Templates
The appendices provide tools you can adapt to your own organization, including:
Fillable System Security Plan template
POA&M worksheet
Network diagram templates
Machine baseline documentation
Data-flow diagram framework
Policy template pack
110-control quick-reference checklist organized by shop area
CMMC glossary for non-IT owners
Regulatory update log
This book is designed for the owner, operations manager, IT manager, MSP, compliance lead, or cybersecurity professional responsible for a small or midsize manufacturing operation in the defense supply chain.
You don't need to become a cybersecurity expert.
You need to understand what is actually in scope, what needs to be protected, what needs to be documented, and what evidence you need to be able to produce when someone asks you to prove it.
If your shop handles DoD-related technical data and you're trying to make sense of CMMC Level 2, NIST SP 800-171, CUI, SSPs, POA&Ms, SPRS, and C3PAO assessments, this handbook gives you a practical starting point.
Build the program. Document it. Test it. Prove it.
