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.
