Data Integrity Management
When data has been altered by an unauthorized process or individual, we say that it lacks integrity. To maintain integrity, access control is certainly important, but the best assurance that integrity has been maintained is to generate message digests of the relevant data by using hashing algorithms. The values can be used at a later time to verify that the data remains unchanged from the time the message digest was generated.
