You can manage the ability for users and groups to view or modify NiFi resources using access policies. There are two types of access policies that can be applied to a resource:
View - If a view policy is created for a resource, only the users or groups that are added to that policy are able to see the details of that resource.
Modify - If a resource has a modify policy, only the users or groups that are added to that policy can change the configuration of that resource.
You can create and apply access policies on both global and component levels.
