Data execution prevention
Data execution prevention (DEP) is an exploit mitigation technique mechanism in which a
processor can distinguish the portions of memory that are executable code from data.
Data wipe
iOS provides an option
Erase All Content and Settings
to wipe the data on the iPhone.
This type of data wipe erases user settings and information by removing the encryption
keys that protects the data. As the encryption keys are erased from the device, it is not
possible to recover the deleted data in forensic investigations. Other wiping methods are
available that overwrite the data in the device memory. More information on wiping can

Activation Lock
Activation Lock, introduced with iOS 7, is a theft deterrent that works by leveraging
Find
My iPhone
. When Find My iPhone is enabled, it enables the Activation Lock, and your
Apple ID and password will be required to turn off Find My iPhone, to erase your device,
and to reactive your device.
