MRI read outs are 3d, so can't be printed for analysis. They are gigabytes in size, and the units are usually in a different part of the building. So you could sneakernet cds every time an MRI is done, then sneakernet the results back. Or you could batch it and then analysis is done slowly and all at once. OR you could connect it to a central server and results/analysis can be available instantly.

Smarter people than us have already thought through this and the cost-benefit analysis said "connect it to a server"

So in that case you setup a NAS server that it can push the reports to, everything else is firewalled off.

Its just laziness, and to be honest, an outage like this has no impact on their management reputation as a lot of other poorly run companies and institutions were also impacted, so the focus is on crowdstrike and azure, not them.

I admit I'm not a medical professional but these sound like problems with better solutions than lots of Internet connected terminals that can be taken down by edr software.

Why not an internal only network for all the terminals to talk to a central server, then disable any other networking for the terminals? Why do those terminals need a browser where pretty much any malware is going to enter from? If hospitals are paying out the ass for their management software from epic/etc, they should be getting something with a secure design. If the central server is the only thing that can be compromised then when edr takes it down you at least still have all your other systems, presumably with cached data to work from

Ever heard of a LAN? You don't need internet access for every single machine.

Many X-Rays (MRIs, CT scans, etc.) are read and interpreted by doctors who are remote. There are firms who that's all they do - provide a way to connect radiologists and hospitals, and handle the usual business back-end work of billing, HR, and so on. Search for "teleradiology"

Same goes for electronic medical records. There are people who assign ICD-10 codes (insurance billing codes) to patient encounters. Often this is a second job for them and they work remote and typically at odd hours.

A modern hospital cannot operate without internet access. Even a medical practice with a single doctor needs it these days so they can file insurance claims, access medical records from referred patients and all the other myriad reasons we use the internet today.

Okay, so (as mentioned elsewhere in this thread), connect the offline box to an online NAS with the tightest security between the two humanly possible. You can get the relevant data out to those who need it.

This stuff isn't impossible to solve. Rather, the incentives just aren’t there. People would rather build an apparatus for blame-shifting than actually just building a better solution.

Do you think everyone involved is physically present? The gp was absolutely accurate that you guys have no idea how modern healthcare works and this had nothing to do with externally introduced malware.

This sounds a bit like someone just got ran over by a truck because the driver couldn’t see them so people ask why trucks are so big that they’re dangerous and the response is “you just don’t know how trucks work” rather than “yeah maybe drivers should be able to see pedestrians”.

If modern medicine is dangerous and fragile because of network connected equipment then that should be fixed even if the way it currently works doesn’t allow it.

This is a completely different discussion. They absolutely should be reliable. The part that is a complete non starter is not being networked because it ignores that telemedicine, pacs integration, and telerobotics exist.

If you don't understand why it has to be networked with extremely bad fallback to paper, then I suggest working in healthcare for a bit before pontificating on how everything should just go back to the stone age.

Networking puts their reliability into risk. As shown here, as shown in ransomware cases. It is not the first time something like this happen.

The question is not whether or not hospitals need internet at all or to go back into printing things in paper or whatever nobody ever said. The question is whether everything in the hospital should be connected to the internet. Again the example used was simple. Having the computer processing and exporting the data from an MRI machine connected online in order to transfer the data, vs using a separate computer to transfer the data and the first computer is offline. This is how we are supposed to transfer similar data at my work for security reasons. I am not sure why it cannot happen in there. If you cannot transfer data through that computer, there could be an emergency backup plan. But you need to solve only the transfering data part. Not everything.

even the most secure outbound protection would likely whitelist the CrowdStrike update servers because they'd be considered part of the infrastructure
