Scoped knowledge bases
To protect knowledge bases containing sensitive articles, use a scoped knowledge base. Even system administrators and knowledge administrators can't administer scoped knowledge bases unless explicitly authorized through user criteria.
For example, say you have a knowledge article with sensitive payroll information that should be seen only by the Payroll department and not by a system administrator or knowledge administrator. You could create a knowledge article with the sensitive information in a scoped knowledge base within the Human Resources: Core application.
You can't modify the scope of existing knowledge bases. They remain in the global scope. However, you can create a scoped knowledge base to protect sensitive knowledge articles.
To create a scoped knowledge base for an application, in addition to the knowledge_admin or admin role, you must have access to view and select that application in the application picker (see Application picker). For example, before you create a knowledge base in the Human Resources: Core application, you must select the Human Resources: Core application in the application picker, and then create the knowledge base. Then, when you create a knowledge base, on the Knowledge base form, the application scope of the knowledge base is set in the Application field.
