Documents must be configured to not open as Read Write when browsing.
An XCCDF Rule
Description
By default, when an Office 2013 document on a web server is opened using Internet Explorer, the appropriate application opens the file in read-only mode. However, if the default configuration is changed, the document is opened as read/write. Users could potentially make changes to documents and resave them in situations where the web server security is not configured to prevent such changes.
