Which of the following features of the Zero Trust Exchange helps to reduce attack surface?

The feature of Privileged Remote Access significantly contributes to reducing the attack surface within a Zero Trust framework. This is primarily because it enables secure and controlled access to resources, ensuring that only authorized users can connect to sensitive applications and services. By implementing strict authentication and authorization protocols, this feature minimizes the number of points of entry for potential attackers.

In contrast, Public Access to applications can increase the attack surface since it may allow unauthorized or less secure connections to the application. Open Network Connections may expose systems to various vulnerabilities as they do not enforce strict security measures. Simple Proxy Access could also provide a pathway for broader access without adequately verifying user credentials or context, potentially expanding the attack surface rather than reducing it.

Thus, Privileged Remote Access stands out as a critical feature for minimizing exposure to threats while maintaining secure access to vital resources.
