What type of information gathering is carried out by obtaining details that are freely available on the Internet and through various other techniques, without directly coming into contact with the organization's internal servers

Passive information gathering

Explanation:

Passive information gathering refers to gathering as much information as possible without establishing contact between yourself and the target about which you are collecting information.

In this case, since the details about the organization are obtained from other sources outside the organizations servers, it is a passive information gathering process.

However, if the details were to be obtained directly from the organization's servers, it will be known as active information gathering. This is because contact is now established between the target and the penetration tester.
