GPS OCX passes cybersecurity tests
Raytheon has completed rigorous cybersecurity vulnerability assessment of its GPS next-generation Operational Control System, GPS OCX.
The assessments tested the system's ability to defend against both internal and external cyber threats. GPS OCX prevented the broadcast of corrupt navigation and timing data in all tests, bolstering the programme's readiness for the GPS III launch in December 2018.
GPS OCX is the enhanced ground control segment of a US Air Force-led effort to modernise the US GPS system.
The first tests were carried out in April 2018 and were led by a contracted blue team that aimed to breach the system from within its information assurance boundary. The second round of tests took place in May 2018 and was led by an air force red team of cyber-penetration testers who tried to breach the system's IA boundary from outside.
The assessments took place on the launch and checkout system, GPS OCX Block 0, which was delivered to the air force in 2017 as a fully cyber-secure satellite ground system.
