Where can security be set for viewing, creating, updating, or deleting documents?

Setting security for documents in Appian can be effectively managed at specific levels to ensure that the right users have appropriate access. The correct choice highlights that security can be set at both the Knowledge Center level and the Document Folder level.

At the Knowledge Center level, administrators can define broad security settings that apply to all documents contained within. This simplifies management by allowing a collective permission setup across multiple documents and folders.

Similarly, at the Document Folder level, specific access rights can be assigned that apply exclusively to the documents housed within that folder. This granularity allows for tailored permissions, ensuring that only designated users are able to view, create, update, or delete documents as necessary.

The other options do not provide the same comprehensive approach to managing document security. Although user profiles and application settings play vital roles in overall security configurations, they do not address document-specific security as effectively as the Knowledge Center and Document Folder settings.
