Joe South joins the Security Cocktail Hour to discuss the state of communication satellite security and the doctoral research he is doing to change it. Joe is Director of Cloud & AI Security at Abira Security and hosts the Security Unfiltered podcast, one of the larger independent cybersecurity podcasts. The conversation covers what satellite defense actually looks like today: why most of the security is at the ground station rather than on the satellite itself, what happens when CubeSats stay in orbit for 10 to 12 years without meaningful patching, and how a zero trust framework could be made to work on hardware that operates on less than three watts of power. Joe walks through his proposed approach, which combines TPM-based component authentication with a distributed trust ring across satellite orbits.We also get into cyber warfare and the attribution problem, the strategic implications of a compromised satellite fleet, and Joe's personal story about building self-sufficiency. If you work in cloud, infrastructure, or national security and have never had space in your threat model, this is a good place to start.
