Air-Gapped AI: Security Without Compromise

Technical whitepaper on building fully isolated AI environments with strict controls for data import, model updates, monitoring, and compliance.

Executive Summary

Air-gapped AI deployment represents the gold standard for security-critical environments. This whitepaper provides a comprehensive technical guide to deploying and operating AI systems in fully isolated environments.

Understanding Air-Gapped Requirements

Definition

An air-gapped system is physically isolated from unsecured networks, including the internet. For AI systems, this means:

No network connectivity to external systems
Physical isolation of hardware
Controlled data transfer mechanisms
Manual update processes

Use Cases

Air-gapped AI is essential for:

Defense and national security
Critical infrastructure (power, water, telecommunications)
Financial system core operations
Healthcare systems with sensitive patient data
Government classified information processing

Architecture for Air-Gapped AI

Hardware Requirements

Compute Infrastructure

Dedicated server hardware
GPU accelerators (NVIDIA, Huawei Ascend, Intel Gaudi)
Redundant power supplies
Hardware security modules (HSM)

Storage Systems

Encrypted storage arrays
Backup systems
Secure media handling

Network Infrastructure

Isolated network segments
No external connectivity
Intrusion detection systems

Software Stack

Hardened Linux OS
AI frameworks (TensorFlow / PyTorch)
Optimized inference engines
Vector databases and document processing
Monitoring and logging stack

Data Transfer Protocols

Secure Import Process

1**Data Preparation** on isolated workstation
2**Media Preparation** on approved, encrypted media
3**Security Scan** using multiple engines
4**Physical Transfer** under controlled procedures
5**Import Verification** and integrity checks
6**Audit Logging** for the entire chain

Model Update Process

Validate model externally
Perform security review
Package with cryptographic signatures
Transfer via approved media
Stage to test environment first
Roll out to production with rollback plan

Security Controls

Physical security and facility controls
Role-based access control and MFA
Encryption at rest and in transit
Secure key management and HSMs
Comprehensive logging and monitoring

Operational Procedures

Health and performance monitoring
Security event management
Incident response playbooks
Business continuity and disaster recovery

Compliance Considerations

Alignment with NIST, ISO 27001, and national regulations
Audit-ready documentation
Change and access management records

Conclusion

Air-gapped AI deployment requires significant investment in infrastructure, processes, and expertise. For organisations handling sensitive data or critical operations, this investment is essential to unlock AI value without compromising security or sovereignty.
