Nmap Fundamentals: Network Scanning and Security Mapping

Understanding what is running on your network is the first and most critical step in securing it. This text-based course introduces you to Nmap, the industry-standard tool for network discovery, security auditing, and vulnerability assessment. You will progress from understanding basic networking concepts to executing precise scans, interpreting command-line output, and identifying potential security gaps. By the end of this course, you will have a solid foundation in network mapping techniques used by security professionals worldwide. What you'll learn: - Understand core networking protocols, IP addressing, and port states - Execute basic and advanced Nmap scans to discover active hosts and open ports - Analyze scan results to identify operating systems and service versions - Apply the Nmap Scripting Engine (NSE) to automate vulnerability detection - Practice safe and ethical scanning techniques within a modern security framework - Interpret scan outputs to strengthen network defenses against common threats The course starts with foundational networking terminology and basic scanning commands. You will then progress to advanced scan configurations, scripting with NSE, and analyzing results to assess your network's security posture. This course is designed for absolute beginners in cybersecurity, system administration, and networking, with no prior scanning experience required.
