FOOTPRINTING
In ethical hacking training footprinting is the first and a vital module.
Footprinting (also known as reconnaissance) is the technique used for gathering information about computer systems and the entities they belong to. To get this information, an ethical hacker might use various tools and technologies. This information is very useful to an ethical hacker who is trying to crack a whole system. Footprinting is basically the first step where hacker gathers as much information as possible to find ways to intrude into a target system or at least decide what type of attacks will be more suitable for the target. This is also a very important step for ethical hacker; he can find possible attacks, vulnerabilities and patch that.
During this phase, a hacker can collect the following information −

• Domain name
• IP Addresses
• Namespaces

• Phone numbers
• E-mails
