The security features of DBF tables are extensive. If you intend to create private tables within dBASE Plus for which you want to set elaborate or varied access levels, the DBF table type is your best choice.

Table-level security relies on data encryption. Data encryption scrambles data so that it can’t be read until it is unscrambled. An encrypted file contains data that has been translated from source data to another form that makes the content unreadable. If your database system is protected, dBASE Plus automatically encrypts and decrypts tables and their associated index and memo files when a user supplies the required passwords or other login information.

In addition, DBF tables allow you to define which fields within tables users can access, and the level of access, read, read/write, or full.
