Network Scanning with Nmap and Essential Security Tools

Understanding how data flows across your network and identifying vulnerabilities is the first line of defense in modern cybersecurity. This course guides you through the fundamentals of network scanning, reconnaissance, and security auditing using industry-standard tools. You will transition from a complete beginner to a confident practitioner capable of mapping networks, analyzing traffic, and identifying potential security risks. Through clear written explanations and practical examples, you will learn how to set up your environment and use essential tools responsibly to secure modern IT infrastructures. What you'll learn: Understand foundational networking concepts, IP addressing, and port states before running your first scan; Install and configure Nmap on Linux, Windows, and macOS environments; Execute basic to advanced network scans to discover active hosts and open ports; Analyze network traffic and capture packets using Wireshark to inspect protocol behavior; Explore the fundamentals of vulnerability scanning and web application security with Metasploit and Burp Suite; Apply modern security practices, including scanning within zero-trust frameworks and securing local network configurations. The course begins with essential terminology and network concepts, then moves step-by-step through installing Nmap and executing your first scans. From there, you will expand your toolkit to analyze packets and understand vulnerability assessment workflows. This text-based course is designed for absolute beginners in cybersecurity, system administration, or IT support, with no prior scanning experience required.
