Re: It will take 1-2 more WannaCries
There's no particular reason why Linux is more secure than Windows.
That is true and anyone who claims to be inherently secure simply because of any particular OS is setting themselves up for a massive pratfall.
However, any up-to-date version of Linux is massively more secure than Windows XP, which ceased being supported years ago. Of course, a modern version of Windows is also secure but the reason XP is still so widely used is because upgrading on the scale of the NHS is so expensive and such a logistical nightmare. Yes, for the sake of security they should have upgraded to Vista, then 7, then 8 and now 10 but the cost and the breaking changes each time made it impossible.
In so far as an upgrade is necessary, and the upgrade will be painful in any event, it makes sense to find a solution that is not going to result in the same problem in another 10 years time.
