Two types of cyber attacks must be distinguished: "On the one hand, those aimed at attacking the integrity, availability or confidentiality of systems or data; on the other hand, information fraud operations aimed at usurping identities, spread false news, and provoke social crises", explains Nicolas Arpagian, author of "Innocence à Crédit" (Éditions Mareuil).

Physical damage is never far away, as we saw recently with the repeated malfunctions at the Corbeil-Essonnes hospital.

And the cyber weapon now prefigures, or accompanies, a land conflict.

It is therefore important to prepare for it by teaching about what the reality of the cyber threat may be in its different technical and informational dimensions.
