>There are many files that are placed in the Bugzilla directory
area that should not be accessable from the web. Because of the way
Bugzilla is currently layed out, the list of what should and should not
be accessible is rather complicated. A new installation method is
currently in the works which should solve this by allowing files that
shouldn't be accessible from the web to be placed in a directory outside
the webroot. See
<A

>Be sure to test that data that should not be accessed remotely is
properly blocked. Of particular intrest is the localconfig file which
contains your database password. Also, be aware that many editors
create temporary and backup files in the working directory and that
those should also not be accessable. For more information, see

To test, simply point your web browser at the file; for example, to
test mozilla.org's installation, we'd try to access
<A
