- Description: A three-tier AI governance model for defense contractors: prohibited, restricted, and permitted AI tools, mapped to the CMMC Level 2 controls that AI usage touches.
- Author: HydratedSec

### Tier 1 - Prohibited

AI tools that process, store, or transmit CUI/FCI. No exceptions without ATO.

- Any AI tool that sends CUI to external servers
- Consumer-grade AI assistants (ChatGPT, Claude) for CUI-related work
- AI-powered translation services processing controlled documents
- Cloud-based OCR/transcription on CUI documents

### Tier 2 - Restricted

AI tools that operate in CUI environments but do not directly process CUI. Requires approval and monitoring.

- AI-powered endpoint security tools in CUI enclaves
- Code assistants used on projects adjacent to CUI systems
- AI-driven SIEM/log analysis in GCC High environments
- Automated vulnerability scanning with AI prioritization

### Tier 3 - Permitted

AI tools operating entirely outside CUI boundaries on non-sensitive work.

- AI writing assistants for marketing content
- Code generation for non-CUI projects
- AI-powered scheduling, HR, or finance tools
- Training and education AI tools

| Control      | Name                           | Why AI usage touches it                                            |
| ------------ | ------------------------------ | ------------------------------------------------------------------ |
| AC.L2-3.1.1  | Authorized Access Control      | Governs who can access AI tools in CUI environments                |
| AC.L2-3.1.2  | Transaction & Function Control | Limits what AI tools can do with controlled data                   |
| AT.L2-3.2.1  | Role-Based Training            | Requires AI-specific security training for CUI personnel           |
| AU.L2-3.3.1  | System Auditing                | Audit logs must capture AI tool interactions in scope              |
| CM.L2-3.4.1  | System Baselines               | Approved AI tools become part of the system baseline               |
| CM.L2-3.4.2  | Security Config Enforcement    | AI tool configurations must meet security requirements             |
| MP.L2-3.8.1  | Media Protection               | AI-generated outputs containing CUI require marking and protection |
| SC.L2-3.13.1 | Boundary Protection            | Network boundaries must account for AI tool data flows             |
| SI.L2-3.14.1 | Flaw Remediation               | AI tool vulnerabilities must be tracked and patched                |
