Here's how you can specialize in network security for cloud computing.

Begin with mastering the basics of network security, including firewalls, IDS, IPS, encryption, and access control. Understand how these components collaborate to safeguard an organization’s information. Use this foundational knowledge to address the unique security challenges in cloud environments. Focus on cloud-specific security protocols and best practices for comprehensive protection.

Specialized Skills Development: Develop specialized skills in areas such as firewall management, intrusion detection and prevention systems (IDPS), encryption, secure network design, and incident response. Acquire hands-on experience with cloud security solutions offered by leading vendors, and seek opportunities to deepen your expertise in specific areas of interest.

It's important to not only understand these basic network security concepts theoretically, but also gain practical hands-on experience working with the technologies. Look for opportunities to set up and configure your own test networks, firewalls, VPNs, etc. Playing the role of both attacker and defender in simulated scenarios will help develop troubleshooting skills. The cloud introduces new complexities, so having a solid foundation through real-world application of traditional network security best practices will serve you well.

L'approche traditionnelle de la sécurité est une approche périmétrique : on protège les contours de notre réseau et l'on fait confiance à ce qui est à l'intérieur. L'évolution des usages Cloud ainsi que l'avénement de l'approche Zero Trust a fait changer ce paradigme. Maintenant il s'agit d'allier la sécurisation des droits et permissions, et de ne plus faire uniquement confiance à des logiques de sécurisations réseaux. On a alors des applications d'entreprises qui se retrouvent exposées sur internet (en mode SaaS exemple GMAIL, GDRIVE) mais qui sont protégées par des accès conditionnels qui sont une combinaison logique (machine, réseau, droits IAM)

Specializing in network security for cloud computing involves mastering cloud platform architectures and network configurations specific to providers like AWS, Azure, and Google Cloud. It's crucial to adopt cloud-native security practices such as configuring virtual networks, implementing identity and access management (IAM), and utilizing encryption for data protection. Familiarity with cloud security tools such as AWS Security Hub, Azure Security Center, and Google Cloud Security Command Center is essential for monitoring and responding to threats effectively. Additionally, integrating automation and DevSecOps practices ensures security is ingrained throughout the development and deployment lifecycle in cloud environments.

From my own experience working with cloud computing environments, understanding the shared security responsibility model was crucial. When I first started in a cloud role, I came from an on-premises background and assumed the cloud provider handled everything. However, I quickly learned that while they manage the underlying infrastructure, gaps remain that users must address - like identity management, encryption of data at rest, firewall configurations in virtual networks, etc. It was an adjustment to wrap my head around what was "lifted and shifted" versus what required new processes. Going through hands-on labs where I had to set up and protect my own cloud resources really drove home that shared model.

Les fournisseurs de services Cloud virtualisent des services novateurs et puissants : ils deviennent alors responsables de la sécurité des couches OSI "inférieures". Néanmoins le client reste toujours responsable de la sécurisation de la donnée (confidentialité, intégrité, disponibilité, tra?abilité, etc.)

Les risques majeurs d'attaque sur le cloud sont les erreurs de configuration API. Une approche standard pour y pallier: - définir sa politique de sécurisation cloud - opérationnaliser cette politique en règles standards à appliquer sur vos environnements - surveiller la conformité de vos environnements à ces standards - réaliser des remédiations continues afin de réhausser votre niveau de sécurité sur le cloud

Les outils du moment pour aider les professionnels de cybersécurité sont le CNAPP/CSPM. Ils permettent de gérer la conformité d'un ensemble de domaine importants: infrastructure, IAM, data, CICD afin de réduire la surface d'attaque ou rendre plus difficile les chemins d'attaques vers les ressources les plus critiques

Stay abreast of the latest developments, trends, and threats in cloud security and networking. Follow industry blogs, attend webinars, and participate in online communities to stay informed. Regularly update your skills by exploring new technologies, tools, and best practices in the field.

Gain practical experience by working on real-world projects involving cloud security. Seek internships, entry-level positions, or freelance opportunities to apply your knowledge in a professional setting. Experiment with setting up secure cloud architectures, implementing access controls, and configuring network security tools.
