Sustaining information integrity requires operating system protection
Usually, IT network environments orchestrate direction and control through an operating system installed to coordinate processes; including application software. In other words, an operating system performs most generally accepted management functions for IT processes.
Without an operating system certain functions, such as multiprogramming, simply would not be an available processing option, and many functions like I/O completion testing would have to be performed directly by a programmer. Therefore, operating systems are the primary catalyst sustaining efficient and effective information integrity. If this viewpoint is adopted throughout the entity, IT owners should ensure adequate protection mechanisms are installed with employed operating systems.
