Is it possible to configure the security settings to limit viewing tickets to only those who are on the ticket? For example, ticket is assigned to "IT" and we want to prevent "Dev Team" from seeing it in the queue.
Yes, that is possible. You would do this with a combination of an issue security scheme that defines who should have access based on the level, and automation that sets the security level based on the assignee. You can learn more about how to configure it here, Configure issue security schemes.
