In the context of Zero Trust, if your phone number is unpublished, what does this imply?

• A. Everyone can access it
• B. Only authorized parties can call you
• C. It can be discovered through social engineering
• D. It is available for all trusted contacts

Answer: (B)

In the context of Zero Trust, an unpublished phone number implies that only authorized parties can access or call you. This aligns with the Zero Trust principle, which emphasizes that no entity, device, or individual should be trusted by default, regardless of their network location. By keeping your phone number unpublished, you restrict access to only those who have been vetted or authorized to reach you. This means that your contact information remains secure from unauthorized access and reduces the risk of unsolicited communications or potential threats. The other choices do not accurately reflect the implications of having an unpublished phone number. Making it available to everyone would create vulnerabilities, while suggesting that it can be discovered through social engineering minimizes the proactive steps taken to secure your contact information. Additionally, stating that it is available for all trusted contacts contradicts the idea of an unpublished number, which is specifically designed to limit knowledge of your contact details to a select group.
