Do you know all of the hosts on your network? Are you *sure*? Do you know if all of those hosts are secure from malicious tampering? In this article, you will learn how to find that information for yourself using three tools: nmap, nessus, and netcat. . nmap is a mature open source project for network exploration and security auditing. nmap has an enormous number of features, of which this article will use only one: the ability to discover hosts on the network. All the examples are from the author's home LAN; your network is probably much more complex. Warning if you intend to experiment with these tools on a corporate network, we strongly advise you to seek the cooperation of your local IT and Network Administration staff. All the of tools described in this article are capable of performing actions that will set off network intrusion detection systems. All of the tools described in this article are capable of performing actions that will likely violate company policies. At some companies, unauthorized possession of these tools behind the company firewall is grounds for immediate termination.

Nmap ("Network Mapper") is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. 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. Nmap runs on most types of computers and both console and graphical versions are available. Nmap is free and open source. .
