UK's security branch says Ubuntu most secure end-user OS
We'll never hear the end of it from the Ubuntu marketing bandwagon !
I hate stupid headlines like that.
If you look at the charts, OS X didn't exactly lag far behind Ubuntu. The only difference was very minor, and was in the Device Update Policy section ("orange" instead of "green"... their marking needs more granularity !!) , so not really of much importance to home-users and I'd need to read the detail to see what the exact detail was as far as businesses was concerned.
Furthermore, Device Update Policy is a management evaluation criteria, rather than security evaluation criteria.
If anything, all that document does is confirm my earlier point made that Mac was as secure as Linux for all intensive purposes. But then I already knew I was right anyway !
(Edit to add: I've dug up the detail, their marking down of OS X from Green to Orange under Device Update Policy was down to
"The enterprise cannot force the user to update their device or software." ..... Apple have been steadily improving their Server software, so I suspect policy enhancements were already in the works long before this publication)
