Data security is an important issue for most corporations. If you plan to create and distribute a phone-directory report for your company, you want to show employee names and phone extensions. You probably don't want people to change the report definition and create a report that includes people's salaries. Another concern is that someone could look at the report definition file, copy a connection string and start browsing (or hacking) your database.

These are legitimate concerns that affect all types of data-based applications, including C1Report. This section discusses some measures you can take to protect your data.
