Nmap (Network Mapper) is a powerful open-source tool widely used in ethical hacking and cybersecurity. It helps security professionals and penetration testers scan networks, discover vulnerabilities, and gather crucial information about target systems. Key Features of Nmap in Ethical Hacking Port Scanning: Identifies open ports on a target machine, revealing potential entry points for attackers. Service and Version Detection: Determines the services running on open ports and their versions, helping detect outdated or vulnerable software. OS Fingerprinting: Analyzes network responses to determine the operating system of a target device. Nmap Scripting Engine (NSE): Allows users to run custom scripts for advanced testing, automation, and vulnerability scanning. Network Topology Mapping: Provides a detailed view of a network’s structure, helping ethical hackers understand the attack surface. Common Nmap Commands Basic Scan: nmap <target-ip> (Scans a target for open ports) Aggressive Scan: nmap -A <target-ip> (Performs OS detection, version detection, and traceroute) Service Scan: nmap -sV <target-ip> (Detects services running on open ports) OS Detection: nmap -O <target-ip> (Attempts to determine the target’s operating system) Script Scan: nmap --script=<script-name> <target-ip> (Runs specific NSE scripts for vulnerability assessment) Nmap is an essential tool for ethical hackers, helping them assess security risks and strengthen defenses.
