Q. The term “Zero Trust Authentication (ZTA)” was seen in the news recently. In this context, which one of the following statements is correct?

[A] It provides a systematic approach to managing sensitive company information, ensuring its confidentiality, integrity, and availability.

[B] It offers a concise and prioritized set of best practices designed to help organizations improve their cybersecurity posture.

[C] It involves layering multiple security measures throughout an information system to provide redundancy in case one layer fails.

[D] It is a security approach that treats all systems, networks, and users as unreliable necessitating ongoing authentication for devices, users, and applications.

Answer: D
Notes:

Explanation – Zero Trust Authentication (ZTA) is a security model that requires all users and devices to be authenticated and authorized before they can access a network or system, regardless of their location or previous authentication status. The model is based on the principle that all network traffic, both internal and external, should be treated as potentially hostile, and that trust should never be assumed. This approach helps to protect against cyberattacks by limiting the access that attackers can gain if they manage to penetrate the network perimeter.
