Use Field-Level Security to control data access is how the administrator should deliver this solution. Field-Level Security is a way to restrict users' access to view or edit specific fields on an object based on their profile or permission set. Field-Level Security can be used to make fields visible or hidden, and editable or read-only for different users. By using Field-Level Security, the administrator can ensure that only Marketing users can see all data on the Membership Details object, while Support users can only see the Support preference fields.

Data categories and visibility are features that allow you to organize and control access to your Salesforce Knowledge articles based on different topics or criteria. Data categories are logical groupings of articles that reflect your business needs and processes. You can create a data category group and assign it to one or more article types, and then create data categories and subcategories within that group. Data category visibility is a setting that determines which data categories users can access based on their profiles or permission sets. You can use data categories and visibility to provide relevant and appropriate product documentation to your customers and support team.
