Description
In the case of a production web server, areas for content development and testing will not exist, as this type of content is only permissible on a development website. The process of developing on a functional production website entails a degree of trial and error and repeated testing. This process is often accomplished in an environment where debugging, sequencing, and formatting of content are the main goals. The opportunity for a malicious user to obtain files that reveal business logic and logon schemes is high in this situation. The existence of such immature content on a web server represents a significant security risk that is totally avoidable. The web server must enforce, internally or through an external utility, the signing of modules before they are implemented into a production environment. By signing modules, the author guarantees that the module has been reviewed and tested before production implementation.
