Reconnaissance – FootPrinting – Information Gathering

The first step for a successful penetration test is reconnaissance, also known as footprinting or information gathering. The main objective of this step is to gather information about the target system. Footprinting can be achieved through steps such as social engineering or by probing and enumerating the network. Information gathering is the most critical. In this stage all relevant information about the company is gathered and used for later steps. In this step we are trying to identify company details, company web sites, ips, open ports, hosts, routers, os details, services details etc..
