If you are looking to implement security, you could use something like Cryptor to encrypt the tables.

You could also set up file level security at the OS level. Only give access to certain accounts. Create a data access object that creates a connection to that directory using WNetAddConnection2 (see Ed Rauh's NETRESOURCE entry in the Files section) or Network object of the Windows Scripting Host. Both allow you to specify a user name and password for connection purposes. Once the connection is made, you can use methods of the data object to pass updates through.
