What I want is Little Snitch on steroids built into the OS where every process, including all native ones, including UI apps, are blocked from network connectivity by default, and the user gets an easy monitor of outgoing traffic with TLS/SSL inspection built in (you'd need some OS API to enable that). Kind of like granular oauth permissions, apps should have to declare which outgoing they have, a description/why, an…

Provided you can add a cert to your OS, you should be able to get away with a piece of protocol downgrade network gear that you can then pipe to a different (ideally, offline other than UDP receive) computer for analysis. You'd need to disable HSTS, but other than that I think it should be the solution you're looking for…

Any application that uses certificate pinning would fail in this situation as that's specifically what it is trying to prevent.

I've raised this point repeatedly in different orgs. It's met with some combination of indifference and lack of understanding and not-my-responsibility-ism, but I'm sure that this will eventually blow up hard in some company's face - like 9-digit settlement for breach of contract, or worse things like breach of export control laws. Enterprise data security on the "MS Office level" at this point is like driving 60 mph…

Yeah, I'm surprised every healthcare related business doesn't either ban PowerPoint or block this "feature" somehow. HIPAA is a hell of a drug.

Powerpoint is the raison d'etre of an entire class of middling bureaucrats. They'll fight tooth and nail to protect their turf and preserve their role in society.

Earlier quoted context omitted.

Same speed limit in the UK, and there are roads without painted lines.

The speed limit and the speed you should be driving are different though

In most of the western US, the speed limit is about 10 mph lower than the actual speed of traffic.

On Windows there is Glasswire[0] for blocking applications that phone home. Just find the offending process and block it. It's not a perfect solution though as Windows 10/11 has hundreds of things that phone home and blocking them has unintended side effects (things crash randomly if they can't talk to the Internet).

> is like driving 60 mph on a road with no lane dividers That’s somewhat funny, because a Landesstraße in Germany has no lane dividers and the speed limit is 100 km/h (about 60 mp/h). Unless I’m misunderstanding and lane dividers mean the printed lines.

the bar to drive in Germany is significantly higher than in the united states. Requirements for getting a drivers license in America is ridiculously lenient because the American lifestyle is completely car centric. taking someone's license away is tantamount to sentencing someone to poverty.

I think the other possible effect is the maintenance construction work in the Autobahn, which can create an upper speed limit anyway.

Also, only about 70% have no speed limit. https://en.wikipedia.org/wiki/Autobahn (ctrl+f "No speed limit" for a nice table)

Can you point to the provision of HIPAA that this is violating?

A well-designed OS API doesn't need to do MitM and therefore would work with HSTS or cert pinning enabled. Of course for obvious reasons, few commercial apps would actually use this API unless they have some other incentive.

Well, the original article was about Microsoft. Since they're the OS vendor too, I discounted that as being reliable for this use-case.

How do you know there are no outside efforts to log linux activities? There's a lot of source code to go through and is it possible there are callbacks even within OSS that most people are not aware of?
