To answer this question, you need to understand the concept of social engineering.
Option A) Social engineering - This option is correct. Social engineering is a technique used to manipulate individuals into revealing sensitive information or performing actions that they wouldn't normally do. Obtaining a password from an employee through oral communication is an example of social engineering.
Option B) Weak authentication controls - This option is incorrect. Weak authentication controls refer to inadequate security measures in place to protect passwords and user credentials. While weak authentication controls can make it easier for social engineering attacks to be successful, it does not directly result in obtaining a password through oral communication.
Option C) Ticket-granting server authorization - This option is incorrect. Ticket-granting server authorization is a concept related to Kerberos authentication, which is not relevant to obtaining a password through oral communication.
Option D) Voice recognition software - This option is incorrect. Voice recognition software is a technology used to identify and authenticate individuals based on their voice patterns. It is not directly related to obtaining a password through oral communication.
The correct answer is A) Social engineering. This option is correct because obtaining a password from an employee through oral communication is an example of social engineering, where the attacker manipulates and deceives the employee into disclosing sensitive information.
