Integrity
Integrity of a system or network is the assurance that information can only be accessed or modified by those who are authorized. Several measures are taken to ensure integrity. These include controlling the physical environment of networked terminals and servers, restricting access to data, and maintaining rigorous authentication practices. Data integrity can be threatened by environmental hazards, such as heat, dust, and electrical surges.
