Yes, it is possible and it does help with security.  You need ResEdit
(maybe simular programs will work).  Go into ResEdit and select the
folder you want to operate on.  Then select "Get Info (command-I)" and
you will then be able to change some attributes.  Set the Invisible
flag.  Now the folder (and all its contents) still exists and can even
be used to some extent.

What we did here is to put all our applications (MacDraw, MacPaint,
etc.) into a folder that was then made invisible.  I had created
sample blank documents that were locked.  These blank documents (one
for each program) were needed to start up an application.  Suppose
someone wants to create a new MacWrite file, he can then open the
sample document and MacWrite will start up (even though it is in an
invisible folder!).  This is not perfect security, but does keep
people from throwing applications into the trash, etc.
