Connecter et protéger : réseaux et sécurité des réseaux from Coursera

Voici le troisième cours de la Certification en cybersécurité de Google. Ces cours vous permettront d'acquérir les compétences dont vous avez besoin pour postuler à un emploi de niveau débutant dans le domaine de la cybersécurité. Vous vous appuierez sur votre compréhension des sujets qui ont été introduits dans le deuxième cours de la Certification en cybersécurité de Google.

Dans ce cours, vous découvrirez comment les réseaux permettent de connecter plusieurs appareils, leur permettant ainsi communiquer. Nous commencerons par présenter les principes fondamentaux des opérations et des protocoles réseau actuels. Par exemple, vous découvrirez la suite des protocoles Internet (TCP/IP - Transmission Control Protocol/Internet Protocol) et comment le matériel réseau, tels que les routeurs et les modems, permet à votre ordinateur d'envoyer et de recevoir des informations sur Internet. Ensuite, vous en apprendrez plus sur la sécurité réseau. Les entreprises stockent et envoient régulièrement des informations importantes sur leurs réseaux ; les réseaux sont donc des cibles courantes de cyberattaques. À la fin de ce cours, vous serez en mesure d'identifier les vulnérabilités au niveau des réseaux et d'expliquer comment sécuriser un réseau à l'aide de pare-feu, de renforcement du système et de réseaux privés virtuels.

Les employés de Google qui travaillent actuellement dans le domaine de la cybersécurité vous guideront à travers des vidéos, des activités pratiques et des exemples qui simulent des tâches courantes de cybersécurité, et vous aideront à développer vos compétences pour vous préparer à l'emploi.

Les participants qui termineront cette certification seront aptes à postuler à des emplois de niveau débutant dans le domaine de la cybersécurité. Aucune expérience préalable n'est nécessaire.

Reviews summary

Réseaux et sécurité : bases essentielles

Selon les apprenants, ce cours est une introduction solide et très claire aux fondamentaux des réseaux et de la sécurité, particulièrement adapté aux débutants sans expérience préalable. Les concepts complexes sont expliqués de manière simple et directe, rendant le sujet accessible. Les vidéos de haute qualité et les explications des instructeurs sont souvent saluées. Bien que les démonstrations pratiques et les labs soient appréciés pour leur aide à la compréhension, certains souhaiteraient plus d'exercices pratiques ou de défis autonomes. Le cours est considéré comme un excellent point de départ pour la certification Google, mais certains ayant déjà des connaissances en IT le trouvent parfois trop introductif ou manquant de profondeur pour aller au-delà des bases.

Contenu pertinent et bien structuré, avec des instructeurs clairs.

"Chaque module est bien structuré et le contenu est très pertinent pour quiconque veut comprendre les bases de la sécurité réseau."

"Les intervenants sont clairs et donnent de bons exemples."

"La qualité de production est top. Les vidéos sont de haute qualité et les explications sont faciles à suivre."

Rend les concepts complexes de réseau et sécurité très accessibles.

"Ce cours est excellent pour les débutants. J'ai vraiment apprécié la façon dont les concepts complexes sur les réseaux et la sécurité ont été expliqués de manière simple."

"J'ai toujours eu du mal avec les réseaux, mais ce cours a rendu le sujet accessible."

"Les explications sont simples et directes, ce qui est parfait pour les non-initiés."

Bénéficierait de plus de cas pratiques et d'exercices moins guidés.

"J'aurais aimé un peu plus d'exercices pratiques pour renforcer l'apprentissage, surtout sur les configurations."

"Les labs étaient un peu trop guidés, j'aurais préféré plus de défis pour appliquer les connaissances de manière autonome."

"Il manque de cas pratiques réels ou des simulations d'incidents de sécurité pour mieux se projeter dans un rôle professionnel."

Idéal pour débutants, mais potentiellement trop superficiel pour les experts.

"Pour ceux qui ont déjà des connaissances de base en IT, certaines parties peuvent sembler un peu trop 'introductives' et répétitives."

"Le cours est correct pour une introduction, mais il manque de profondeur. J'ai eu l'impression que certaines explications étaient trop superficielles..."

"Pour un certificat professionnel, j'attendais plus de défis. Il manque de profondeur pour les personnes qui ont déjà une familiarité avec l'IT."
