A new update of Apple's iOS will change default settings to make it harder for law enforcement to gain access to iPhones.
Many agencies are using devices that go in through the phone's Lightning port. Now devices will lock that port once they have gone unused for more than an hour.
"That port is how machines made by forensic companies GrayShift, Cellebrite and others connect and get around the security provisions that limit how many password guesses can be made before the device freezes them out or erases data. Now they will be unable to run code on the devices after the hour is up."
This change will be rolled out to everyone in a forthcoming release.
