Is there a way to secure documents in confluence to prevent someone from viewing or downloading the document? We would like to secure a page/space and the attachments on that page but still allow others to have access to other pages on that site. We have an HR space where HR keeps general content for the company (tavel, 401k, etc) They also want to keep performance reviews on their space for managers to keep track of their employees (they upload the reviews as doc). We can restrict the page, but the site also has the 'attachments' page and we can see the documents. Any way to lock this down or suggestions on a way to secure this content?
