Re: [Model-t] What are we trying to protect

[Eric Rescorla <[e-mail]>]

his seems like a reasonable problem statement for the overall problem of
computer security, but not really for IETF.

To take a concrete example memory reading attacks like Spectre are a threat
to user data and something that browser vendors spend a fair amount of
energy working on, but they're mostly not in scope for IETF [0]. There's
nothing wrong with that, it's just division of labor.

[0] I say "mostly" because (a) we need to take the security implications of
these kinds of attacks in our protocol designs and (b) there might be some
small pieces of IETF work like CORB, though that seems to be mostly being
done elsewhere.
