How can you restrict an administrator's access to certain ADOMs?

An administrator's access to certain ADOMs in FortiAnalyzer can be effectively restricted by assigning specific ADOMs to the admin's account. This approach allows for granular control over what administrative users can see and manage within the FortiAnalyzer environment. By explicitly designating which ADOMs an administrator can access, you ensure that they only have visibility and control over the data and configurations relevant to their role.

This method is particularly useful in environments where multiple teams manage different ADOMs, as it enhances security by minimizing unnecessary access and reducing the risk of errors or inappropriate changes to configurations outside of an administrator's purview. The direct assignment aligns the administrator's responsibilities with their respective ADOMs, streamlining operations and governance within the system.

Other options, while potentially useful in different contexts, do not directly control access to ADOMs. For example, creating a new admin role or configuring user groups can influence permissions, but they would require additional setup and do not specifically limit access to the individual ADOMs like the direct assignment method does. Time restrictions simply control when users can access the system rather than what parts of the system they can access.
