OS Integrity
Definition
• System integrity is the ability of an operating system to prevent the
circumvention or bypassing of its security, auditing, or accounting controls
by any program, or person not authorized to do so.
• Therein lies the issue, allowing authorized persons and programs to bypass
these controls while simultaneously restricting that ability to those
unauthorized.
• An operating system has system integrity when:
• it is designed, implemented and maintained to ensure that
unauthorized users and unauthorized programs cannot bypass the
functions that protect other users or programs,
• applications cannot obtain control in an authorized execution state, and
cannot bypass the system-level security functions.
