Information Gathering is a technique or we can say that it is the first phase of ethical hacking, in which we gather as much information as possible about our target. That target can be a website, a web application, an IP address, a person, or anything in general. If you target something for a particular reason, let us suppose for hacking, you will need a lot of information about that, which can be useful for you in the future for exploiting the target. It is a process of knowing the target, digging information about our target, and being in touch with our target.
Basically, the information gathering is of two types:
Active Information Gathering
Passive Information Gathering
