Ethical Hacking Fundamentals and Network Security

In an increasingly digital world, securing networks and systems from malicious actors is more critical than ever. Understanding how attackers think is the first step toward building robust defenses. This text-based course guides you through the foundational pillars of ethical hacking, networking, and security analysis. You will transition from a complete beginner to someone who can confidently identify vulnerabilities, understand network protocols, and apply security frameworks to protect digital assets. What you'll learn: Understand the roles, responsibilities, and legal boundaries of an ethical hacker; Analyze core networking concepts, including the TCP/IP stack, IP addressing, and network topologies; Apply penetration testing methodologies, such as black-box, grey-box, and white-box models; Identify common system vulnerabilities and modern threat vectors; Explore modern security paradigms like Zero Trust and secure network configuration; Practice defensive strategies and vulnerability assessment techniques through written scenarios. Starting with essential security terminology and basic networking, the course moves systematically into scanning techniques, penetration testing methodologies, and modern defense frameworks. This course is designed entirely for beginners, requiring no prior cybersecurity experience or technical background. Read on to take your first step into the world of ethical hacking.
