What is the primary concern of the Zero Trust security model?

The primary concern of the Zero Trust security model revolves around the principle of "never trust, always verify." This approach emphasizes stringent access control management, which involves verifying the identity of users and devices before granting access to resources, regardless of whether they are inside or outside the network perimeter.

In a Zero Trust architecture, the idea is to treat every access request as a potential threat. This means constantly assessing and authenticating users, devices, and their behaviors in real-time to ensure that only authorized access is granted. As a result, access control management becomes a cornerstone of Zero Trust, focusing on ensuring that individuals and systems are vetted and monitored continuously to mitigate security risks effectively.

Other options touch on important aspects of security, but they do not capture the essence of the Zero Trust model as completely. Monitoring external threats is certainly essential in cybersecurity, but it doesn't fully encompass the comprehensive verification processes central to Zero Trust. Similarly, packet management and filtering pertain to network security but are more tactical measures rather than strategic principles guiding user access. User behavior analytics can play a role in Zero Trust by providing insights into user actions, yet it is a tool within the broader framework rather than the primary focus. Therefore, understanding that access control management is the critical aspect of
