Visual Tempest Inspections (VTI) / Instrumented TEMPEST Surveys (ITS)

ISHPI understands that with the modernization of military aircraft, ships and cutters a myriad of inspections and surveys must be performed to ensure the security of communications before each asset becomes operational. All new assets have systems and applications on-board that are increasingly interconnected to provide the most robust capabilities to operators, and these new capabilities present numerous ways for communications to be compromised by adversaries. To combat this problem, rigorous planning and execution of TEMPEST instrumented surveys and inspections are required to ensure that these systems are inspected and tested to effectively safeguard all electronic emanations from these platforms.

ISHPI has been providing TEMPEST support to the USCG since 2008, working with CG-9335 and the C4IT-SC Certified TEMPEST Technical Authority (CTTA) to perform Visual TEMPEST Inspections (VTI) and Instrumented TEMPEST Surveys (ITS). This includes work with The Space and Naval Warfare Systems Command (SPAWAR), providing TEMPEST services on the USCG National Security Cutters (NSC). Our Secure Communications Support includes the creation, verification, validation, and maintenance of documentation for USCG communications systems.

As a familiar and trusted TEMPEST expert, our Field Technical Authority (FTA) provided services that mitigated Congressional concerns over the USCG Cutter Bertholf. Working in conjunction with the both U.S. Government and contractor counterparts, ISHPI personnel repaired approximately 500 Visual TEMPEST Inspections (VTI) discrepancies and conducted significant Instrumented TEMPEST Surveys (ITS), resulting in a successful certification and Authority to Operate (ATO) by the Approving Official. ISHPI’s certified TEMPEST FTA also participated in the first update to the TEMPEST Manual since 1995.
