"System integrity" in computer systems ensures the accuracy, consistency, and trustworthiness of information and operations within the system. It protects data from unauthorized access, alteration, or destruction, thereby maintaining a reliable environment where users can trust the results produced by the system. Ensuring system integrity involves implementing measures such as encryption, access controls, and regular audits to mitigate potential threats. This oversight is crucial for organizations that rely on data-driven decision-making and need to safeguard sensitive information and maintain operational continuity.
