I wonder what's the best practice when end-users upload confidential information to SP10, such as clients' SSN, competitor's private info, or military weapon contracts for various governments. And all the information is now searchable, roll up to enterprise search results.
How should we squeeze out those data in the search results in the server?
I'm using SharePoint 2013, so I would turn off the search ability for that library and the site immediately. At least the results won't show up anymore. What to do if it's a SharePoint 2010 environment and what's the best practice for this situation?
