What Makes AJAX So Different?
The AJAX Disadvantage
AJAX is a very powerful weapon but one must be aware of the security vulnerabilities that exist. Some developers have the misconception that AJAX applications offer tighter security because it is believed that the server-side script can’t be accessed without the rendered user interface, which is simply the AJAX-based page. Unfortunately, this couldn’t be further from the truth. The mere factor of increased interactivity within the application results in increased text, XML and HMTL network traffic. This in turn, could lead to the exposure of back-end applications that may have not vulnerable otherwise. Without adequate server-side protection, it could also give unauthenticated users the ability to manipulate privilege configurations.
While the evolution of web technologies has enabled applications to enjoy more responsive, interactive, efficient functionality, they also increase the vulnerabilities developers and businesses face on a daily basis. The growing prevalence of AJAX applications has considerably broadened the threat window, essentially giving hackers a greater opportunity to compromise sensitive data and thieve invaluable assets. For this reason, developers must stop living under a false sense of security and take every measure possible to ensure that their AJAX applications are completely secure.
