Web Security, Privacy and Commerce, 2nd Edition

16.8 Conclusion

Writing secure web applications is a difficult task. Any program that runs on your web server can potentially compromise the security of the entire system. To make things worse, no amount of testing will tell you if your programs are error-free. The solution to this apparent dilemma is to follow strict rules when writing your own programs and then to have those scripts carefully evaluated by someone you trust. Good luck!
