Every organization, in the course of its activities, produces or acquires information that is organized and managed by its information system.

The data and associated information constitute the real assets of this activity, and for this reason, it is necessary to protect them legally, technically, procedurally, and organizationally. For more information on information security within an information system, visit our section on Technical Information Security and Legal Information Security.

The information system and its dimensions

The information system of an organization consists of several dimensions:

  • Infrastructure dimension
  • Organizational procedures dimension
  • Human resources dimension

information system

The infrastructure dimension includes the environments where the organization operates and its computer system, which represents the automated part of the information system.

The organizational procedures dimension reflects the organization and management of activities within processes, specifying tasks, functions, and roles necessary for the organization's functioning.

The human resources dimension consists of the individuals who perform their work activities within the organization and utilize information from the information system to carry out their assigned processes.

The evolution of communication systems and the widespread use of information technology have led to the majority of information systems being predominantly computer-based.

Security in information systems

Information systems are not isolated entities: they interact with each other and, more generally, with the external world, exchanging data.

This raises the issue of information security in its broadest sense, concerning the three mentioned dimensions as well as the interaction between information systems.
