In this presentation on Nmap Tutorial for beginners, we cover the basic explanation and operation of nmap. We also have a nmap vulnerability scan tutorial at the end of our lesson where we use Nmap to run multiple scans and breach a windows computer. This nmap hacking tutorial also lists the different modes of scanning and a couple of alternative tools to be considered. 1. Introduction 2. Phases In Ethical Hacking 3. What Is N-Map? 4. Modes of Operation 5. Alternatives to N-Map 6. Live Demonstration Nmap (Network mapper) It is a free and open-source Linux command-line utility for scanning IP addresses and ports for installed services. Nmap allows network administrators to identify network devices, open ports and services, and vulnerabilities. Gordon Lyon created Nmap to rapidly map a network and locate available ports and services. Along ith the Nmap custom scripting engine, it also supports simple commands (such checking a host's status). About Simplilearn Ethical Hacking Course: This Certified Ethical Hacker-Version 10 (earlier CEHv9) course will train you on the advanced step-by-step methodologies that hackers actually use, such as writing virus codes and reverse engineering, so you can better protect corporate infrastructure from data breaches. This ethical hacking course will help you master advanced network packet analysis and advanced system penetration testing techniques to build your network security skill-set and beat hackers at their own game. Why is the CEH certification so desirable? The EC-Council Certified Ethical Hacker course verifies your advanced security skill-sets to thrive in the worldwide information security domain. Many IT departments have made CEH certification a compulsory qualification for security-related posts, making it a go-to certification for security professionals. CEH-certified professionals typically earn 44 percent higher salaries than their non-certified peers. What are the course objectives? Simplilearn’s CEH v10 Certified Ethical Hacker training (earlier CEH v9) and certification course provide hands-on classroom training to help you master the same techniques that hackers use to penetrate network systems and leverage them ethically to protect your own infrastructure. This extensive ethical hacking course focuses on 20 of the most popular security domains to provide a practical approach to essential security systems. You will learn to assess computer system security by using penetration testing techniques; scan, test and hack secure systems and applications, and gain hands-on experience with sniffing, phishing and exploitation tactics.

7. What Is N-Map?
• Open source and free network scanner created by
Gordon Lyon
• Used during reconnaissance stage of hacking
• Can discover hosts and services on a system by the
responses received
• Finds vulnerable ports and services on a network
