The war against space hackers: how the JPL works to secure its missions from nation-state adversaries

NASA’s Jet Propulsion Laboratory designs, builds, and operates billion-dollar spacecraft. That makes it a target. What the infosec world calls Advanced Persistent Threats — meaning, generally, nation-state adversaries — hover outside its online borders, constantly seeking access to its “ground data systems,” its networks on Earth, which in turn connect to the ground relay stations through which those spacecraft are operated.
