I found out by chance that files (pdf) which I meant to be hidden securely by using the lockdown plugin seem to be open to the public simply by using google to search for certain keywords. I have warehoused these files so that the project files is not that big anymore, but have no password protection installed to my warehouse. Thus google is indexing all the files that I want to be hidden!
What are good options to protect these resources asap?
Can I put a password protection on my warehouse folder and still import these files into my lockdown plug-in?
How can I minimize the potential damage, i.e. stop the access to the files that have been indexed? Will changing the filenames do the trick?
