DHS Program Seeks to Address Critical Infrastructure GPS Vulnerabilities

The Department of Homeland Security's science and technology directorate aims to help industry increase the resilience of critical infrastructure assets to GPS interference through a multiyear program.

DHS said Friday the directorate uses a multi-pronged approach to conduct vulnerability and impact assessments, develop mitigation plans, explore complementary timing systems and engage companies through outreach meetings or events.

S&T wants to collaborate with industry to create a voluntary “assured timing compliance framework” meant to address position, navigation and timing vulnerabilities in the country's electric grid, communications and financial networks.

The directorate hosted an event to provide infrastructure operators and GPS equipment manufacturers the chance to test and evaluate platforms in an interference environment.

Sarah Mahmood, an S&T program manager, said the 2018 GPS Equipment Testing for Critical Infrastructure event helped department personnel to establish relationships with industry and served as a component of the program.
