I have a database, that has linked tables to the backend. The front-end is locked down so that the shift key can't be used, etc. and then the file was changed into an mde file so it can't be changed.

However, unfortunately, someone can still create a new database, import tables and import the tables from that mde file, and then they are linked directly to the back-end tables where they can read or modify any data they want.

Is there any way that anyone knows to protect this without implementing MSAccess security?
