Keeping Your Programs Secure.

Cyber security attacks for the aerospace and defense industries continue to increase in frequency and sophistication.

The Department of Defense recently issued new contract clause – DFARS 252.204–7012, in an effort to safeguard covered defense information and cyber incident reporting.

The DoD, its’ contractors and subcontractors must provide adequate security to safeguard DoD controlled technical information resident on or transiting through their unclassified information systems.


HL Precision has been selected to partner with the Digital Manufacturing and Design Innovation Institute (DMDII) to develop an understanding of costs, capabilities, and effectiveness of DoD-required cyber security measures for manufacturing operations.

Network infrastructure will be analyzed by DoD project contractor and generate suggested changes if any, to achieve compliance with requirements. HL is proud to have the opportunity to positively impact the manufacturing competitiveness and security of the United States Government.
