Network Security Scanning with Nmap for Penetration Testing

Understanding what is running on a network is the first and most critical step in securing it. This text-based guide teaches you how to leverage Nmap, the industry-standard tool for network discovery and vulnerability assessment. You will transition from understanding basic networking concepts to executing sophisticated network scans, identifying open ports, detecting operating systems, and uncovering security weaknesses. By the end of this course, you will be able to confidently audit network infrastructures and integrate scanning into modern security workflows. What you'll learn: - Understand foundational networking principles, IP protocols, and port states - Configure and execute basic to advanced Nmap scanning techniques - Detect active hosts, open ports, and running services on target networks - Analyze target operating systems and software versions accurately - Apply the Nmap Scripting Engine (NSE) to automate vulnerability detection - Practice stealth scanning techniques while understanding modern firewall and IDS evasion - Integrate network scanning results into broader penetration testing and security assessment workflows This course begins with essential networking terminology and basic command structures before guiding you through practical scanning scenarios, script automation, and security analysis. It is designed for beginners interested in cybersecurity, ethical hacking, or systems administration, with no prior penetration testing experience required.
