Tools for Executing CGI Safely
If you're using Perl as your CGI scripting mechanism, there are a number of new tools and modules you can use to assure that your CGI scripts operate correctly and safely. These modules are consistently maintained and updated, and the authors are fully aware of all of the potential problems that face the Webmaster when introducing the CGI risk to his or her Web. We'll be introducing these tools and modules in Chapter 5, "Putting It All Together."
Note:
It's fairly trivial to write a Perl script to perform a specific task as a CGI if you're an experienced Perl programmer. So why bother learning how to use a specific module to perform a task if you can hack up something offhand? The risks of doing this probably are in proportion to the experience of the scriptor and his/her familiarity with the CGI-related risks, but in the long run, the added value of learning and using the appropriate module will definitely outweigh the bother of learning to use it. Hopefully, this will become evident to you as you read this book.
