Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics.
It was designed to rapidly scan large networks, but works fine against single hosts.
5.61TEST4 brings the following improvements:
- A spidering library for recursively crawling web sites, and a bunch of scripts to make use of it.
- A vulnerability management library (vulns.lua) for providing consistant output and reporting of discovered vulnerabilities.
- 51 new scripts, bringing the total to 297 in this release!
