Re: Easy to mitigate
then you find oncology devices that cost millions and only work on XP. or BMS systems that only work on Win2k (yep! Preston hospital im looking at you) granted the BMS was VLan'd and not routed. the best you can do is vlan or partition off on a private physical network.
in an ideal world everthing will be patched and upgraded. in the NHS the funds arent there or worse still contracted out so you arent allowed to touch it.
