1 Network Basics

To start off strong in network security, you must grasp the basics of networking. This includes understanding protocols like TCP/IP, which is the backbone of internet communications, and how data is transferred across networks. Familiarize yourself with network topologies, routing, switching, and the OSI model—a conceptual framework used to understand network interactions. Knowledge of these fundamentals is crucial as they are the building blocks upon which security measures are implemented. Without a solid understanding of how networks operate, it's challenging to effectively secure them against potential threats.

Modes de communication dans un réseau. Les échanges de données dans un réseau s'effectuent de différentes manières?: la communication s'adresse à un seul utilisateur (communication?point à point?ou?unicast), à un groupe restreint d'utilisateurs (communication de type?diffusion restreinte?ou?multicast) ou à l'ensemble des usagers d'un réseau (diffusion générale?ou?broadcast). Adressage Toute ressource d'un réseau est désignée par un identifiant ou?nom. à ce nom, on fait correspondre une?adresse?qui dépend généralement du réseau utilisé. L'adresse doit être unique au sein du réseau concerné. Ainsi, dans le réseau téléphonique, le numéro de téléphone est l'??adresse?? d'un abonné connu par son nom.

2 Security Principles

Once you've got the networking fundamentals down, it's time to delve into core security principles. Learn about confidentiality, integrity, and availability—often referred to as the CIA triad—which are the key objectives of network security. Understanding how to achieve and maintain these principles is essential. You should also become familiar with different types of cyber threats, such as malware, phishing, and denial-of-service attacks, and the security measures used to combat them, including firewalls, intrusion detection systems (IDS), and encryption.

3 Hands-On Skills

Hands-on experience is invaluable in network security. You should practice setting up and configuring network components such as routers and switches. Additionally, get comfortable with using network monitoring tools to analyze traffic and detect anomalies. Learning to use penetration testing tools to identify vulnerabilities in a network before attackers do is also crucial. These practical skills will not only solidify your understanding of theoretical concepts but also prepare you for real-world challenges.

Les différents types de scripts et leurs utilisations Scripts shell: Utilisés pour automatiser des taches dans un terminal (Linux, macOS). Ils permettent de manipuler des fichiers, exécuter des commandes, contr?ler des processus, etc. Scripts PowerShell: Similaires aux scripts shell, mais spécifiques à Windows. Ils offrent des fonctionnalités plus avancées pour gérer les systèmes d'exploitation Windows. Scripts Python: Très polyvalents, ils sont utilisés dans de nombreux domaines (data science, développement web, automatisation). Scipts JavaScript: Exécutés dans les navigateurs web, ils permettent de rendre les pages web interactives et dynamiques. Scripts Bash: l'automatisation sur les systèmes Unix-like.

5 System Administration

Understanding system administration is vital because securing a network also involves securing the devices connected to it. This includes managing user privileges, configuring operating systems, and ensuring systems are patched with the latest security updates. A network is only as secure as its weakest link, which often lies in unsecured end-point devices. By mastering system administration, you can ensure comprehensive security across all aspects of the network.
