C\u2019est pourquoi il est essentiel que les organisations fassent \u00e9galement leurs devoirs.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tenez-vous inform\u00e9 des cyber-\u00e9v\u00e9nements actuels qui perturbent diff\u00e9rentes r\u00e9gions, diff\u00e9rents secteurs et diff\u00e9rents groupes, ainsi que des types d\u2019attaques les plus susceptibles d\u2019avoir un impact sur votre entreprise.

Contrairement aux sauvegardes classiques, les SIRE sont intentionnellement stock\u00e9s \u00e0 distance du r\u00e9seau principal afin que les donn\u00e9es ne puissent pas \u00eatre infect\u00e9es ou supprim\u00e9es en cas de cyberincident ou d\u2019autre sinistre.

Pour prot\u00e9ger leurs pr\u00e9cieux ensembles de donn\u00e9es et processus, les entreprises ont besoin d\u2019une visibilit\u00e9 sur les donn\u00e9es et de syst\u00e8mes \u00e0 l\u2019\u00e9preuve des d\u00e9faillances qui leur permettent de continuer \u00e0 fonctionner, m\u00eame si les hackers se font une place. J\u2019ai mentionn\u00e9 ci-dessus comment une plateforme d\u2019analyse rapide des donn\u00e9es de journal peut ex\u00e9cuter des recherches rapides et corr\u00e9ler les \u00e9v\u00e9nements afin d\u2019identifier les signes d\u2019acteurs potentiels des menaces dans votre environnement avant qu\u2019elles ne frappent. Un stockage de donn\u00e9es hautement performant comme Pure Storage peut ing\u00e9rer et analyser les anomalies en temps r\u00e9el, ce qui permet \u00e0 vos \u00e9quipes de chasse aux menaces de rep\u00e9rer les intrus qui se cachent sur votre r\u00e9seau avant que les dommages ne se produisent.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-4-adopt-super-immutable-backup-solutions\"><strong>4. Adopter des solutions de sauvegarde ultra-immuables<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Sans immuabilit\u00e9, les donn\u00e9es de sauvegarde deviennent tout aussi vuln\u00e9rables aux infections que votre jeu de donn\u00e9es principal. Ransomware ont \u00e9volu\u00e9 pour cibler sp\u00e9cifiquement les syst\u00e8mes de sauvegarde, rendant les strat\u00e9gies de protection classiques inefficaces. Ces attaques modernes par ransomware mettent d\u00e9lib\u00e9r\u00e9ment les sauvegardes \u00e0 l\u2019\u00e9preuve avant de lancer leur attaque principale, ce qui garantit que les victimes n\u2019ont pas d\u2019options de reprise \u00e0 part le paiement de la ran\u00e7on.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Les sauvegardes immuables constituent une barri\u00e8re formidable contre les attaques de ransomware, les suppressions accidentelles et m\u00eame les menaces internes malveillantes avec des privil\u00e8ges \u00e9lev\u00e9s. Il suffit de restaurer ces copies intactes sans payer de ran\u00e7ons, ce qui limite les temps d\u2019arr\u00eat et les pertes financi\u00e8res.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Contrairement aux autres solutions, les <a href=\"https:\/\/blog.everpuredata.com\/fr\/products\/protegez-vos-donnees-contre-les-attaques-de-ransomware-avec-les-snapshots-safemode\/\"><strong>snapshots SafeMode\u2122<\/strong><\/a> sont immuables et ne peuvent pas \u00eatre supprim\u00e9s (supprim\u00e9s), modifi\u00e9s ou chiffr\u00e9s par des ransomwares ou des acteurs malveillants. Elles sont prot\u00e9g\u00e9es par une authentification multifacteur et n\u00e9cessitent un processus de v\u00e9rification strict en plusieurs \u00e9tapes impliquant l\u2019\u00e9quipe de support de Pure Storage pour apporter des modifications. SafeMode g\u00e9n\u00e8re automatiquement des snapshots immuables \u00e0 intervalles personnalisables, ce qui vous garantit de disposer en permanence de versions \u00e0 jour et non modifi\u00e9es de vos donn\u00e9es. Des strat\u00e9gies configurables robustes pour la fr\u00e9quence des snapshots, la r\u00e9tention et la r\u00e9plication vers diverses destinations emp\u00eachent les attaquants de compromettre l\u2019ensemble de votre strat\u00e9gie de sauvegarde. SafeMode peut effectuer les restaurations 10 \u00e0 20 fois plus rapidement que les solutions concurrentes. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Gr\u00e2ce \u00e0 cette combinaison de protection et de capacit\u00e9 de reprise rapide, les sauvegardes immuables sont un \u00e9l\u00e9ment essentiel de toute strat\u00e9gie moderne de cyber-r\u00e9silience.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-key-to-organizational-success-is-resilience-and-agility\"><strong>La r\u00e9silience et l\u2019agilit\u00e9 sont les cl\u00e9s du succ\u00e8s organisationnel<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Cette Journ\u00e9e mondiale de la sauvegarde est un rappel opportun pour les organisations qui souhaitent r\u00e9\u00e9valuer leur approche et leurs outils de s\u00e9curit\u00e9. Mais l\u2019impact positif de la r\u00e9silience et de la protection des donn\u00e9es va bien au-del\u00e0 d\u2019une simple journ\u00e9e.
