CGI programming involves designing and writing programs that receive their starting commands from a Web page-usually, a Web page that uses an HTML form to initiate the CGI program. The HTML form has become the method of choice for sending data across the Net because of the ease of setting up a user interface using the HTML Form and Input tags.

CGI is the first and remains one of the most widely-used means of extending Web servers by interfacing external applications, offering various advantages. However, the power of CGI comes with a price. CGI interfaces can completely compromise a Web server's security, and thus of the host on which it is running.
