Network and Perimeter Ethical Hacking Fundamentals

Every organization relies on a secure network perimeter to keep malicious actors out, yet these boundaries are constantly tested by sophisticated network-level attacks. Understanding how attackers bypass defenses is the first step in building a resilient security posture. This text-based course guides you from foundational networking concepts to perimeter defense strategies, teaching you to think like an ethical hacker to identify and mitigate vulnerabilities in network traffic, firewalls, and intrusion detection systems. You will learn to: Understand foundational network protocols and how traffic sniffing occurs; Analyze common perimeter threats including denial-of-service (DoS) attacks and session hijacking; Evaluate the mechanics of social engineering and how human factors compromise network security; Explore techniques used to test and bypass firewalls, intrusion detection systems (IDS), and honeypots; Apply modern Zero Trust principles to strengthen perimeter defenses against sophisticated evasion tactics; Practice identifying vulnerabilities through structured written scenarios and conceptual exercises. The course begins with essential networking terminology and core security concepts before moving into practical methodologies for testing firewalls, analyzing packets, and securing network boundaries. Designed for aspiring security professionals, IT administrators, and beginners curious about cybersecurity, this course requires no prior hacking experience.
