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

Roles are used within User Criteria to grant specific permissions, but they are not the feature that limits access on their own for KBs.

Groups are used within User Criteria to grant access to a collection of users, but they are not the feature that limits access on their own for KBs.

Categories are used to organize knowledge articles within a knowledge base and do not control access permissions.

User Criteria allows administrators to define flexible conditions, often based on roles, groups, or other user attributes, to precisely control who can read or contribute to a specific knowledge base or individual knowledge articles. This granular control ensures sensitive information is only accessible to authorized personnel and contributions come from relevant users.
