iOS 12 Security Guide
The iOS security guide is out! I’m so proud of the Secure Enclave team’s work on the secure storage IC, Kernel Integrity Protection, System Coprocessor Integrity Protection, Boot Progress Register
No reviews are mentioning iPhones XS, XR, and Watch 4 are the most secure iOS devices ever.
A12 and S4 devices now:
- use ARM signed pointers for all Apple software
- have new physical anti-replay counter circuit in Secure Enclave
- mitigate USB DFU hijacking in enclave firmware
If you’re wondering about authenticated pointers in the new iPhones, this is the best plaintext description of how something like that works I’ve seen so far.
Previously: iOS 12 Released.
