Authentication is a critical aspect of information security, aiming to verify the identity of users accessing systems and data. The most common authentication mechanisms are categorized into several factors, including "Something You Know," "Something You Have," and "Something You Are." These factors can be used individually or combined to enhance security.
Here is a detailed explanation of each factor:
1. Something You Know (สิ่งที่คุณทราบ)
This factor refers to information that the user knows, such as a password, PIN, or answer to a security question. It is the most common form of authentication but also the most vulnerable to attacks such as phishing, social engineering, and brute force attacks.
