Find well known vulnerabilities on the scanned systems (using NSE scripts).What operating systems are running on the identified IP addresses.What services are running on the open ports (together with service versions etc).What ports are open on these IP addresses.What IP addresses are live on the network (i.e what IPs have hosts running on them).NMAP is an excellent utility to help you in the reconnaissance phase since you can collect information such as: This is the reconnaissance phase of a security test.

In a penetration testing project you need first to “map” and identify as much information about your targets so that to plan your next steps. Disclaimer: Network Scanning and hacking is illegal unless you have permission. The tool that I use in almost all penetration testing engagements is the famous NMAP scanner (short for Network Mapper tool). One of my responsibilities in the company I work is to perform security assessments and penetration testing on the external and internal systems of the enterprise. NOTE: For a more comprehensive NMAP Tutorial with all popular and useful commands you can download this Nmap Cheat Sheet PDF here. There are hundreds of scan options with NMAP but I will start with the most useful one which is to scan a range of IP addresses together with some other extra options. The purpose of this article is to describe how to perform a simple NMAP scan of an IP range/subnet on a network. This tutorial marks the beginning of a series of network security and penetration testing articles that I will be posting on this website.
