The Nmap Scripting Engine is a bot belonging to website Nmap. Nmap (Network Mapper) is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap itself is around for many years and is often depicted as typical hacking software in movies. Wikipedia adds to this that Nmap is a tool that can be used to discover services running on Internet connected systems. Like any tool it could potentially be used for black hat hacking, as a precursor to attempts to gain unauthorized access to computer systems; however, Nmap is also used by security and systems administration to assess their own networks for vulnerabilities- i.e. white hat hacking.
