Nmap (Network Mapper) is a powerful and widely used open-source tool for network discovery, security auditing, and vulnerability assessment. It helps security professionals, system administrators, and penetration testers gather information about live hosts, open ports, running services, operating system versions, and network vulnerabilities. Originally designed for scanning large networks, Nmap is flexible enough to work on small networks and even single hosts. It supports different types of scans, including TCP, UDP, SYN, and OS fingerprinting, making it a crucial tool in cybersecurity.

Some key features of Nmap include:
• Host Discovery: Identifies live hosts on a network.
• Port Scanning: Detects open ports and services running on them.
• OS Detection: Determines the operating system of a target.
• Service Version Detection: Identifies software versions running on open ports.
• NSE (Nmap Scripting Engine): Automates vulnerability detection and exploitation.
Nmap is widely used in penetration testing and red teaming to map out network structures, detect weaknesses, and gather intelligence for further attacks. Its flexibility, speed, and extensive scripting capabilities make it a go-to tool for ethical hackers.
