Le cloud, M365 et les sauvegardes sont aujourd\u2019hui des briques essentielles des syst\u00e8mes d\u2019information.<\/p>\n\n\n\n
Mais lors d\u2019une crise cyber majeure, le probl\u00e8me ne se limite pas \u00e0 la perte de donn\u00e9es. Les incidents impliquent souvent :<\/p>\n\n\n\n
Des comptes compromis,
Une propagation lat\u00e9rale,
Une perte de confiance dans le SI,
Voire la coupure volontaire de certains outils pour contenir l\u2019incident.<\/p>\n\n\n\n
Dans ce contexte, les principales difficult\u00e9s deviennent rapidement :<\/p>\n\n\n\n
La coordination des \u00e9quipes,
La communication,
L\u2019acc\u00e8s aux informations essentielles,
Et le pilotage de la cellule de crise.<\/p>\n\n\n\n
Les sauvegardes permettent de reconstruire. Les outils collaboratifs permettent de travailler au quotidien. La continuit\u00e9 op\u00e9rationnelle pendant la crise impose parfois des moyens d\u00e9di\u00e9s et ind\u00e9pendants du fonctionnement habituel du SI.<\/p>\n
