The safety of information is a process aiming at protecting from the data against the access, the use, the diffusion, the destruction, or the modification not - authorized.

The Sécurité of the Information is confined neither with the computing systems, nor with information in its digital form or electronics. On the contrary, it applies to all the aspects of safety, the guarantee, and the protection of a data or information, whatever its form.

Definition

The majority of the definitions of the safety of information tend to target, some time exclusively, on specific uses or particular mediae. In fact, the safety of information cannot be defined like synonym of the Computer security, of safety system and network, the safety of the Technologies the information, of the Information system security, or the safety of information the Technologies and the communication. Each one of these expressions deals with different subject, even if the common point relates to the safety of information in some of its forms (here, in its electronic form): consequently, all are under-fields of the safety of information.

Criteria of sensitivity

Another is also often accepted (under various names):

Other important aspects
