EXO Security and Governance: Offline Model Management Training Course

Offline EXO Deployment for Government

• Utilizing EXO_OFFLINE to prevent runtime internet access during operations.
• Pre-loading models into EXO_MODELS_READ_ONLY_DIRS from trusted internal mirrors to ensure secure model deployment.
• Verifying the integrity of model weights using SHA-256 checksums and signed model cards to maintain data accuracy and security.
• Running EXO in air-gapped networks without HuggingFace dependencies to enhance operational security for government environments.

Dashboard and API Access Control for Government

• Installing and configuring reverse proxies (nginx, Caddy) with TLS termination to secure web services for government use.
• Implementing role-based access control for the EXO dashboard and REST API to ensure appropriate user permissions and data protection.
• Using macOS keychain or Linux pass to securely store secrets required for API authentication in government systems.
• Restricting administrative endpoints to specific source IP ranges to limit unauthorized access and enhance security for government operations.

Cluster Isolation and Network Security for Government

• Segmenting EXO clusters using EXO_LIBP2P_NAMESPACE and VLANs to isolate network traffic and enhance security in government networks.
• Configuring host firewalls (macOS application firewall, iptables, nftables) to control access to EXO ports and prevent unauthorized connections.
• Preventing unauthorized device discovery and rogue node injection to maintain the integrity of government systems.
• Encrypting libp2p traffic between nodes when RDMA is not available to ensure secure communication within government clusters.

Model Governance and Provenance for Government

• Building an internal model registry with approved model lists and metadata to support governance and compliance in government operations.
• Tagging and versioning quantized weights (4-bit, 8-bit) alongside source checkpoints to maintain a clear audit trail of models used in government systems.
• Enforcing that only specific HuggingFace repositories or internal artifacts can be loaded to ensure the use of trusted sources for government applications.
• Documenting model lineage, license terms, and acceptable use policies to support transparency and accountability in government operations.

Audit Logging and Compliance for Government

• Configuring EXO log forwarding to immutable audit trails (SIEM, WORM storage) to ensure reliable and tamper-proof record-keeping for government oversight.
• Correlating API call logs with user identity and timestamp to provide a clear audit trail of system interactions for government compliance.
• Capturing events such as model instance creation, deletion, and inference requests to maintain comprehensive records for government operations.
• Generating periodic compliance reports for internal and external auditors to ensure adherence to regulatory requirements in government environments.

Threat Modeling and Incident Response for Government

• Identifying potential threats such as data exfiltration through model outputs, prompt injection, and side-channel leaks to protect government systems.
• Implementing prompt monitoring and content filtering pipelines to detect and prevent malicious activities in government operations.
• Creating incident response runbooks for cluster compromise scenarios to ensure a rapid and effective response to security incidents in government environments.
• Isolating affected nodes, preserving forensic logs, and rebuilding clean environments to mitigate the impact of security breaches in government systems.

Physical Security and Hardware Boundaries for Government

• Securing Thunderbolt ports against unauthorized RDMA cable connections to prevent physical access threats in government facilities.
• Using secure enclaves and Apple Silicon hardware attestation where applicable to enhance the security of government systems.
• Controlling physical access to clustered Macs and shared storage to ensure that only authorized personnel can interact with government equipment.
• Documenting hardware lifecycle and decommissioning procedures to maintain the integrity and security of government assets.

Regulatory Considerations for Government

• Mapping EXO deployments to GDPR, HIPAA, and SOC 2 requirements to ensure compliance with relevant regulations in government operations.
• Maintaining data residency by keeping inference on-premise to protect sensitive government information.
• Documenting vendor supply-chain risks (MLX, EXO, model weights) to identify and mitigate potential security vulnerabilities in government systems.
• Preparing for AI governance frameworks such as the EU AI Act Article 53 to ensure ongoing compliance with evolving regulatory standards for government use.
