The Orange Book (which defined A/B/C security) was mostly about
compartmentalization, how to keep people with different levels of
clearance, or just no "need to know", away from each other on shared
mainframes. With an eye towards the possibility that some of those
people on the inside might be hostile actors.

It was obsolesced by computers becoming cheap enough that you just
didn't share resources between disjoint departments, and other
factors.

No doubt when networks were introduced they developed similar concerns
on shared networks within secure facilities but these weren't shared
with public networks in general (I'm sure there were exceptions, these
are huge organizations.)

So it wasn't about how to securely take credit card and other
information from otherwise unvetted parties across uncontrolled public
networks.

It was about keeping information marked confidential out of the hands
of the people down the hall if they had no clearance.

I think the disconnect here is "public networks" and commerce etc on
those public networks.

Yes computer and network security has long been an active topic, some
of it going back before the first ARPAnet projects (e.g., Multics,
rings of security, ca 1969.)

But securing commerce and connection to an open, public network was a
new idea beyond logins, passwords and similar.

When was the first RFC regarding anything much beyond logins and
passwords? I could go look.

Anyhow, Apples vs Orange Books.
