This question is in regards to Computer Security:

By Brute Force attack, the hackers are identifying secret data by testing all possible combinations.

Lets take time here to discuss authentication: this is the verification that the users claimed identity is valid, and is verified through a password during the logon procedure.

There are three types to consider with authentication: Type 1: Something you know, such as a PIN or password Type 2: Something you have, such as a smart card Type 3: Something you are, such as a fingerprint

Whats your take regarding this practice of giving confidential information over the phone without authentication? Why does it continue to happen?
