1. Build a Practical Technology Control Plan (TCP)

A Technology Control Plan defines how your team prevents unauthorized access to defense articles and ITAR technical data. The TCP becomes the reference point for every security decision on the shop floor and in your systems.

Each TCP should clearly cover how you prevent deemed exports, how you control access, and how you monitor compliance.

Essential TCP components include:

• Identification of all ITAR-controlled technical data and defense articles

• Access control procedures with U.S. person verification requirements

• Physical and electronic security measures for manufacturing systems

• Visitor management protocols for facility tours and demonstrations

• Training requirements and compliance monitoring procedures

Once your TCP defines who can access technical data, the next step is protecting that data with strong encryption everywhere it lives.

2. Use FIPS 140-2+ Encryption for CAD and CNC Data

ITAR compliance requires end-to-end encryption using FIPS 140-2 validated modules for data at rest and in transit across manufacturing systems. Technical data such as CAD files, CNC programs, and engineering specifications must use these validated cryptographic modules.

The following table shows which standards remain valid through 2026 and which ones new implementations should adopt.

Standard	Level	Use Case	2026 Update
FIPS 140-2	Level 2+	Manufacturing data	Accepted through Sept 2026
FIPS 140-3	Level 2+	New implementations	Current standard
AES-256	N/A	Data at rest	Recommended minimum
TLS 1.3	N/A	Data in transit	Required for new systems

3. Lock Down Access with Least Privilege RBAC

Role-based access control keeps ITAR-controlled data available only to authorized U.S. persons who need it for their work. Manufacturing environments benefit from separate roles for pipeline operators, developers, and administrators to limit blast radius from compromised accounts.

RBAC implementation checklist:

• Define role hierarchies based on job functions and data access needs

• Implement multi-factor authentication for all manufacturing system access

• Run regular access reviews with automated deprovisioning when roles change

• Integrate RBAC with enterprise identity management systems

4. Keep ITAR Data Safe in Backups and Recovery

Backups of ITAR-controlled technical data must stay inside U.S. jurisdiction and use the same validated encryption standards as live systems. Cloud storage for ITAR data requires U.S. regions of AWS GovCloud, Microsoft GCC High, or Azure Government to maintain compliant data residency.

Backup security requirements:

• Apply the same FIPS 140-2 encryption standard to backups to protect data at rest

• Store these encrypted backups only in ITAR-compliant cloud environments or secured on-premises facilities

• Implement customer-managed encryption keys so providers cannot view unencrypted data

• Test recovery procedures regularly with documented validation to confirm backups remain usable

• Maintain backup logs throughout this process to support audit trail requirements

5. Protect Servers and Workstations with Physical Security

Strong physical security prevents unauthorized people from reaching systems that store or process ITAR-controlled data. Physical security requirements include restricting access to data centers and server rooms, escorting visitors, and supervising maintenance.

Physical security measures include:

• Controlled access to manufacturing areas with ITAR data systems

• Badge systems that verify and track U.S. persons

• Visitor escort procedures with detailed access logging

• Secure disposal of media containing technical data

• Environmental monitoring and intrusion detection

6. Train Employees on ITAR and Daily Data Handling

ITAR compliance requires annual training on data identification, markings, and deemed exports to foreign nationals. Training should match each role’s responsibilities in the manufacturing process.

Training program components:

• ITAR fundamentals and manufacturing-specific requirements

• Technical data identification and proper handling procedures

• Deemed export prevention in collaborative environments

• Incident reporting procedures and escalation paths

• Regular assessments and documentation of training completion

7. Use FedRAMP-Compliant Cloud for ITAR Workloads

FedRAMP authorization defines standardized security controls for cloud services that protect ITAR-controlled technical data. These controls support continuous monitoring and U.S. data residency.

Cloud security requirements:

• Deploy only in the FedRAMP-authorized environments mentioned earlier for backup storage

• Implement customer-managed encryption keys for all ITAR workloads

• Configure network segmentation and private endpoints

• Enable comprehensive audit logging and monitoring

• Restrict administrative access to screened and documented U.S. personnel

8. Control Vendors and Supply Chain Data Sharing

Vendors and partners must follow strict controls so ITAR-controlled technical data does not leak through shared platforms. Recent breaches exposed defense manufacturing data through compromised vendor file sharing platforms lacking proper access controls.

Supply chain security measures:

• Vendor ITAR compliance verification and due diligence

• Secure file sharing platforms with MFA requirements

• Technical data sharing agreements with clear restrictions

• Regular vendor security assessments and audits

• Incident response coordination with supply chain partners

9. Run Regular Audits and Maintain Documentation

ITAR security assessments require System Security Plans, Plans of Action and Milestones, and internal self-assessments against NIST 800-171 controls. These records show that your controls work over time, not just on paper.

Audit requirements include:

• Quarterly internal security assessments

• Annual third-party compliance audits

• Continuous monitoring of access controls and data flows

• Documentation of remediation activities and timelines

• Preparation for DDTC compliance reviews

Ensure audit readiness with Precision Advanced Manufacturing’s documented processes and traceability systems. Schedule a compliance consultation to review your documentation gaps.

10. Prepare an Incident Response Plan for Breaches

ITAR incident response plans must support quick detection, containment, documentation, and DDTC reporting when data is compromised. A written plan keeps your team aligned during high-pressure events.

Incident response procedures:

• Immediate containment and impact assessment

• Forensic analysis and evidence preservation

• DDTC notification within required timeframes

• Remediation planning and implementation

• Post-incident review and process improvements

11. Secure Kitting and Finishing Workflows

Manufacturing workflows must protect technical data from the first CAD import through final assembly and finishing. Kitting operations need special attention because they combine components, labels, and technical documentation in one place.

Workflow security measures:

• Secure transfer of CNC programs to manufacturing equipment

• Protected storage of work instructions and quality documentation

• Controlled access to finishing specifications and procedures

• Traceability systems linking components to source technical data

• Secure disposal of temporary manufacturing documentation

12. Scale Security Across Prototype and Production

ITAR compliance must work the same way during prototype runs and full-rate production. Security controls should scale without slowing down throughput or creating manual workarounds.

Scalable security implementation:

• Automated security controls that scale with production volume

• Consistent data protection across prototype and production phases

• Integrated quality and security documentation systems

• Standardized security procedures for multi-shift operations

• Continuous monitoring and compliance validation
