Integrity is the principle that safeguards reliability, accuracy, and completeness of information assets.  Integrity safeguards ensure modifications are not made by unauthorized users and that unauthorized modifications are not made by authorized users. Integrity controls also ensure information is current and has not been altered or damaged. The ‘official’ definition of integrity is: Guarding against improper information modification or destruction, including ensuring information non–repudiation and authenticity. [44 U.S.C., SEC. 3542].
