Memory protection is a way to control memory access rights on a computer, and is a part of most modern operating systems. The main purpose of memory protection is to prevent a process from accessing memory that has not been allocated to it. This prevents a bug within a process from affecting other processes, or the operating system itself. Memory protection for computer security includes additional techniques such as address space layout randomization and executable space protection.

Famous quotes containing the words memory and/or protection:
“Language was not powerful enough to describe the infant phenomenon. “I’ll tell you what, sir,” he said; “the talent of this child is not to be imagined. She must be seen, sir—seen—to be ever so faintly appreciated.”... The infant phenomenon, though of short stature, had a comparatively aged countenance, and had moreover been precisely the same age—not perhaps to the full extent of the memory of the oldest inhabitant, but certainly for five good years.”
—Charles Dickens (1812–1870)
“After so many historical illustrations of the evil effects of abandoning the policy of protection for that of a revenue tariff, we are again confronted by the suggestion that the principle of protection shall be eliminated from our tariff legislation. Have we not had enough of such experiments?”
—Benjamin Harrison (1833–1901)
