Building protection systems against the threat of information integrity violations and access denial
The concept of data integrity in the scientific literature has several definitions. In one of the most common interpretations, data integrity refers to the absence of inappropriate changes. The meaning of the concept of "improper modification" is revealed by D. Clark and D. Wilson: no user of an automated system, including an authorized one, should be allowed to make such changes to data that will lead to their destruction or loss.
Violation of the integrity of information occurs either with unauthorized access to information, or without it.
The threat to integrity exists at all stages of information life:
during storage;
processing;
transportation.
