  5. 5. Features • Nmap was first published in September 1997 • Included operating system fingerprinting • Service fingerprinting • Code rewrites (C to C++) • Additional scan types, • Protocol support • New programs that complement Nmap's core features
  6. 6. How Nmap Works 1) Sends TCP and UDP packets to the target machine 2) Examines the response by comparing the result with the database 3) OS detection involves the process of finding open ports 4) Ping scan uses ICMP packets to check live machines within the network 5) Nmap is not limited to merely gathering information and enumeration
