What feature allows you to limit who is able to contribute or read knowledge within a knowledge base?

Roles provide broad access permissions across the platform, but User Criteria offers more refined control for knowledge base access by combining roles with other conditions.

Groups organize users, and while they can be part of User Criteria, they are not the sole feature that limits access to knowledge bases in a comprehensive manner.

User Criteria is a powerful ServiceNow feature specifically designed to define conditions, based on roles, groups, or other user attributes, to control read and contribute access to Knowledge Bases and individual Knowledge Articles.

Categories are used to organize knowledge articles within a knowledge base for easier navigation and are not used for defining access control.
