One of the most useful but less known trick in a fully managed Oracle UCM production site, for example ImageSource, Inc., is to prevent content editing on a web site. By default, a managed or dynamic site allows the content owners to enter the contributor mode by navigating to web pages and hit a standard hot key Ctrl + Shift + F5. This mode is all fine and useful in development and contribution servers, but it is a no no in a production environment.
Below is a screen shot of how to disable the contributor mode on your UCM production server. Navigate to Administration for Servers | General Configuration and add the highlighted text.
Hope this helps.
