Network Scanning Fundamentals for Penetration Testing

To secure a network, you must first understand exactly what is running on it. Network scanning is the critical reconnaissance phase of penetration testing that reveals active hosts, open ports, and potential entry points. This text-only course guides you from the absolute basics of network protocols to executing precise, secure scans. You will learn how to analyze network traffic, identify operating systems, and detect vulnerabilities while understanding the modern zero-trust security context. What you'll learn: - Understand foundational networking concepts, IP addressing, and the TCP/IP handshake - Discover active hosts and map network topology using industry-standard scanning techniques - Analyze open ports, services, and operating systems using Nmap and command-line tools - Identify common network vulnerabilities and misconfigurations safely and ethically - Apply modern scanning practices aligned with zero-trust security architecture principles - Practice interpreting scan logs and network traffic captures through written scenarios The course begins with essential networking definitions and terminology before moving into scanning methodologies, tool configurations, and analysis techniques. It is designed for aspiring penetration testers, system administrators, and cybersecurity beginners, with no prior scanning experience required.
