Sécurité informatique pour la gestion des risques

The safety of a system corresponds to the non-occurrence of events that could diminish or damage the integrity of the system and its environment throughout the duration of the system's activity, whether successful, degraded or failed. Security covers both random (danger) and deliberate (threat) events.

This article focuses on the application of computer security techniques to scientific and technical programmed systems.

Scientific and technical programmed systems mainly comprise :

• on-board systems in cars, trains, airplanes, medical equipment, weapons systems... ;

• control-command systems for industrial installations in the nuclear and chemical sectors... ;

• telecommunication systems ;

• scientific computing systems.

Before reading this article, it is recommended that you read the general concepts relating to security and risk management of IT systems described in the article [SE 2 500] "IT security for risk management – Application to information systems".

A table of acronyms is given at the end of the article.
