It's Way Too Easy To Hack the Hospital (bloomberg.com)
schwit1 sends along a lengthy piece from Bloomberg about the chaos currently surrounding medical device security: The Mayo Clinic had assembled an all-star team of about a dozen computer jocks, investigators from some of the biggest cybersecurity firms in the country, as well as the kind of hackers who draw crowds at conferences such as Black Hat and Def Con. The researchers split into teams, and hospital officials presented them with about 40 different medical devices. Do your worst, the researchers were instructed. Hack whatever you can.
Like the printers, copiers, and office telephones used across all industries, many medical devices today are networked, running standard operating systems and living on the Internet just as laptops and smartphones do. Like the rest of the Internet of Things—devices that range from cars to garden sprinklers—they communicate with servers, and many can be controlled remotely. As quickly became apparent to Rios and the others, hospital administrators have a lot of reasons to fear hackers. For a full week, the group spent their days looking for backdoors into magnetic resonance imaging scanners, ultrasound equipment, ventilators, electroconvulsive therapy machines, and dozens of other contraptions. The teams gathered each evening inside the hospital to trade casualty reports.
"Every day, it was like every device on the menu got crushed," Rios says. "It was all bad. Really, really bad." The teams didn't have time to dive deeply into the vulnerabilities they found, partly because they found so many—defenseless operating systems, generic passwords that couldn't be changed, and so on.
Sooner or later, hospitals would be hacked, and patients would be hurt. He'd gotten privileged glimpses into all sorts of sensitive industries, but hospitals seemed at least a decade behind the standard security curve. "Someone is going to take it to the next level. They always do," says Rios. "The second someone tries to do this, they'll be able to do it. The only barrier is the goodwill of a stranger."

It's not just medical devices. Anything reasonably proprietary has historically had the security by obscurity defense and that hasn't changed. Why do you think manufacturers of SCADA gear, connected sensors, etc. beg customers to put them on their own disconnected network?
Putting systems that could cause death or widespread mayhem on isolated networks is a good idea regardless of the security of the applications. It's one more layer an attacker has to bypass.
The problem is that doing so has become an excuse to NOT secure the applications.
