It really depends on the definition of a 'valid command'.

PS: It reminds me of the guy that was able to capture the GPS coordinates of an airplane broadcasted to the In-Flight Entertainment systems and got a lot of press coverage by extrapolating that it meant he could also take control of the aircraft from his seat in the cabin. Says who ? What validation ? If an operator had the right to have a telecommand sent to the satellite, who or what aboard the satellite should decide if this telecommand was legitimate.įrom experience, there is a myriad of things that you think are usually not a good idea to make your satellite do and then, when you need it as a workaround or mitigation for an unexpected condition, you are happy you have not implemented a list of authorized actions that is too constrained. > a satellite should be designed so that TCs do not compromise the satellite’s stability without further validation Larger machinery typically used more commercial off-the-shelf components and was thus more vulnerable since the code base was public, whereas smaller CubeSats tended to use custom code. > One surprising result was that the larger the satellite, the more vulnerable it was. * I was astounded when I discovered the level of casualness for everything related to security on scientific satellite projects, with even recent projects led by major agencies considering that always encrypting command and monitoring is overkillĪnd my main grip is that the study relies on asking universities that have the lowest bar in terms of caring about security (they already struggle enough to build a working thing) and then extrapolating from a specious argument that it must be worse on commercial spacecrafts. * I am not sure when this level of security became standard and what was done to secure the satellites before hardware-level encryption with modern algorithms became available * I started working on satellites in a large industrial group where, while not being handled by world class cybersecurity experts, secure communications with the satellites rely on a sane use of proven encryption protocols I have an intimate knowledge of how what I help design works but a limited knowledge of what others may be doing. From what I read in the PDF, the analysis is very debatable (with The Register putting forward mostly the nonsensical allegations).ĭisclosure: I work on satellite design and in the recent years on a program that is part of the NewSpace.
