Space cybersecurity starts on the ground.
Though spacecraft are important, space cybersecurity extends well beyond these assets touching ground stations, mission-control assets, and other critical components.
Host Maria Varmazis speaks with Milenk Starcik, Head of Cybersecurity at Vision Space, and Andrzej “Andy” Olchawa, Senior Cybersecurity Engineer also at Vision Space, about the broader space cybersecurity attack surface. By considering all aspects of a space mission, both in orbit and on the ground, cybersecurity professionals can better understand where vulnerabilities exist and what measures can be taken to reduce risk.

Defending Space as Critical Infrastructure.
Space infrastructure has become an increasingly important part of everyday life, which has also made it an increasingly attractive target for exploitation.
Host Maria Varmazis and Sean MacKirdy, Area Vice President for the National Security vertical at Elastic Government Solutions, sit down to discuss how space stakeholders need to reevaluate their approach to securing space systems. As space systems continue to grow more important, malicious actors are going to look to target them more often. By adopting a stronger universal framework and a consistent way to interpret data across all spacecraft, space cybersecurity practitioners will be able to standardize their practices and create more effective and timely responses.
