Secure Storage for Model Registries

Security Requirement

Only authenticated and authorized users MUST be able to access the storage where models are stored. Unauthorized access to model storage can lead to model theft, tampering, or injection of malicious models.

Required Controls

Control	Description
Authentication	All access to storage requires authenticated identity
Authorization	RBAC controls over read, write, and delete operations
Encryption at rest	Model files encrypted on the storage backend
Access logging	All storage access operations logged
Network isolation	Storage accessible only from authorized networks/services

Access Control Matrix

Role	Read Models	Write/Upload	Delete	Admin
Inference engine (service)	Yes	No	No	No
ML engineer	Yes	Yes (with approval)	No	No
Model pipeline (CI/CD)	Yes	Yes	No	No
Registry admin	Yes	Yes	Yes	Yes
Unauthorized	No	No	No	No

Implementation Checklist

• Require authentication for all access to model storage
• Implement RBAC with least-privilege roles for storage operations
• Enable encryption at rest on the storage backend
• Restrict network access to storage (internal only, use network policies)
• Log all storage access operations for audit
• Regularly audit storage access permissions
• Disable anonymous or public access to model storage
