The connection-cat is out of the bag, and the benefits (various kinds of remote collaboration) are too big to put it back (never mind that viruses were perfectly happy to indiscriminately spread on diskettes back in the days). The lesson to be learned is to start taking in-depth cyber security seriously, in this cases of WannaCry and Petya, specifically, vigilant constant patching and upgrading of all systems. Management needs to understand that if they can't afford to staff an IT department to this end, then can't afford to have computers, and IT departments need to understand this stuff, not just trust whatever snake oil salesman invited them to Vegas - especially that software tied to specific versions of other software (Windows and IE are common culprits, but far from the only one) must itself be updated (or else scrapped) the moment the other software receives an update - it must never be allowed to hold back a security update.
