[$] Protecting update systems from nation-state attackers
Frequent updates are a key part of keeping systems secure, but that goal
will not be met if the update mechanism itself is compromised by an
attacker. At a talk during the 2019 Open Source Summit Japan, Justin
Cappos described Uptane, an update
delivery mechanism for automotive applications that, he said, can prevent
such problems, even when the attacker has the resources of a nation state.
It would seem that some automobile manufacturers agree.
