أمن الشبكات والقرصنة الأخلاقية: دفاعات طبقة الشبكة

100% of the networks are vulnerable to attacks, and the network security is a critical component of the security of the Internet. Every digital interaction relies on a secure network infrastructure, yet networks remain prime targets for malicious exploits. Understanding how attackers compromise network layers is essential for anyone looking to build a career in cybersecurity or secure their own systems. This text-based course guides you through the foundational concepts of networking, vulnerability assessment, and defensive strategies.\n\nYou will gain a practical understanding of how network protocols work and how security professionals identify weaknesses. Through clear written explanations, practical scenarios,and guided exercises, you will transition from a beginner to someone who can confidently analyze network traffic, identify potential attack vectors, and implement robust security controls.\tn\tWhat you'll learn:\n- Understand foundational networking concepts, including IP addressing, subnetting, and OSI model.\n- Analyze network trafic using sniffing techniques to identify vulnerabilities and unencrypted data.\n - Explore how network-layer attacks such as Man-in-the-Middle (MitM) and ARP spoofing are executed and prevented.\n
