The next era will be of Offline Apps because of stuff like this

I'm kind or envisioning some young bright engineer realizing they could just store some files locally. "It's like.. we don't need a backend at all!"

We are lucky that physics is limiting the latency and bandwidth of the internet, since otherwise local storage could truly disappear.

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…

pf is built into macOS. There is a (paid) frontend - https://www.murusfirewall.com

This post is dubious at best. It makes a “do your own research claim” without sharing anything concrete. Yet, this plays into people’s own confirmation biases so it’s already being taken verbatim by people here.

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.

Wouldn't it be easier to ban putting HIPAA protected information into a PowerPoint? We don't ban telephones just because an employee can read patient records over the phone.

Earlier quoted context omitted.

That assumes people actually have the capacity to examine the source to do so and make the requisite adjustments. The real answer IMHO is to control your networking stack outside of your computer instead. Firewall that and you have way better security

How do you do packet inspection when they're all encrypted?

You can still inspect whether you’re having packets sent when you add text or just when you click on certain options

You could add large amounts of text and see if the packets increase proportionally.

You can perhaps analyze which apps or extensions are sending packets.

This post doesn’t provide enough information of value

With the compiler that you verified and built yourself :)

Itself built with a compiler you verified and built yourself.

If you're putting PHI in a presentation, you probably already have HIPAA problems.

On Linux there is OpenSnitch that does its job nicely, although I experienced some occasional desktop slowdowns even after training it to open everything for trusted programs. https://github.com/evilsocket/opensnitch I still recall the old days of Windows when I tried Kerio Personal Firewall and realized how much software already phoned home two decades ago. That was the last wake up call that pushed me into getting…

I second OpenSnitch, I haven't face any shutdowns due to it yet. For those coming from LittleSnitch on macOS might have to look into the finer details of the connection in the Allow/Deny dialog on OS to get the best results.
