Secure scripts with Apache Suexec
For many admins, the security of a web application is more important than its performance. If you have a web server with multiple users, the Suexec module can help you avoid problems associated with globally writable directories.
If you follow security mailing lists, you know that web applications can be security nightmares. The reason for this is the subject of heated debate. Are languages like PHP to blame? Do too many web developers simply lack the skills to write secure applications? Whatever the cause, one thing is certain: something’s got to change. A holistic approach that redevelops every web server component from scratch is highly unlikely. Instead, the protagonists of the Apache project are working on improving individual components; although most people agree that this is not a perfect solution, it is infinitely better than no solution.
