DTOO179 - Documents must be configured to not open as Read Write when browsing.

Information

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.

Solution

Set the policy value for User Configuration >> Administrative Templates >> Microsoft Office 2013 >> Tools | Options | General | Web Options... >> Files 'Open Office documents as read/write while browsing' to 'Disabled'.
