What type of control governs access to the UI server in Zscaler?

The type of control that governs access to the UI server in Zscaler is role-based administrator control. This type of access control is designed to restrict access to the user interface based on the roles and responsibilities of each administrator. By assigning roles, Zscaler ensures that users can only perform actions that are relevant to their job functions, enhancing security and preventing unauthorized access to sensitive settings and data.

This approach is essential in large organizations where multiple administrators may have different levels of access and responsibility. It allows for granular control over who can view or modify configurations, manage users, or access reports. This structure not only facilitates compliance with internal policies and regulations but also helps mitigate risks associated with human error or malicious intent.

In contrast, the other types of controls mentioned do not specifically pertain to the administration of the UI server. Time-based access control focuses on restricting access during certain time periods, while location-based access control relies on the geographical location of the user to determine access rights. Network-based access control restricts access based on the network from which the user is connecting, rather than their role within the organization. Hence, role-based administrator control is the most relevant and effective means of governing access to the UI server in Zscaler.
