Apple says that System Integrity Protection is a necessary step to ensure a high level of security. In one of the WWDC developer sessions, Apple engineer Pierre-Olivier Martel described unrestricted root access as one of the remaining weaknesses of the system, saying that "[any] piece of malware is one password or vulnerability away from taking full control of the device".
For Data at Rest protection a computer or laptop is simply powered off. The disk now self-protects all the data on it. The data is safe because all of it, even the OS, is now encrypted, with a secure mode of AES, and locked from reading and writing. The drive requires an authentication code which can be as strong as 32 bytes (2^256) to unlock.

Often, these systems contain information at various levels of security classification.

The sandbox metaphor derives from the concept of a child's sandbox—a play area where children can build, destroy, and experiment without causing any real ...
