Not really. Unless you encrypt the data, there is always ways that a determined hacker can get to it. The DBF is an open standard and the files are easy to get to. Anyone with Excel for example can open them.

You can, to a point, add some protection for VFP programs using DBC events. (See DBC events in the help files).

You can encrypt sensitive fields with the Windows CryptoAPI. All the tools needed are already in Visual FoxPro. Look in the Component Gallery (VFP7+ IIRC) for the crypto samples.

Or you can also encrypt the whole table on the fly with 3rd party utilities like Cryptor.

If you really want better data security you need to move your back end to a stronger database, like SQL Server or similar (note: VFP comes with MSDE in the CD, which will five you more security).
