Security in iOS 11

Apple has been getting more and more detailed about documenting the end-to-end security in iOS in the last few years as part of its broader focus on security, encryption and privacy.

As part of that, they have been publishing security white papers detailing both hardware and software security in their mobile OS.

They recently published the latest version of this in a document with the scintillating title of iOS Security. [PDF]

It’s well worth a read and always fascinating to me to see both the lengths they go to to appropriately hide the complexity of the technological solution from the user (who shouldn’t need to worry about it) and also the benefits they get from designing both the hardware and software.

The exploitation of flaws to do with speculative execution in modern processors is a fascinating story and the technical details are very interesting but, well, highly technical.

Raspberry Pi founder Eben Upton did a really nice job of explaining it in a non-technical (or at least highly simplified way) and its worth a read if you are curious to learn what all the fuss is about:

Why Raspberry Pi isn’t vulnerable to Spectre or Meltdown
