AJAX - Security

AJAX Security: Server Side

  • AJAX-based Web applications utilize the same server-side security schemes of regular Web applications.

  • You specify authentication, authorization, and data protection requirements in your web.xml file (declarative) or in your program (programmatic).

  • AJAX-based Web applications are subject to the same security threats as regular Web applications.

AJAX Security: Client Side

  • JavaScript code is visible to a user/hacker. Hacker can use JavaScript code for inferring server-side weaknesses.

  • JavaScript code is downloaded from the server and executed ("eval") at the client and can compromise the client by mal-intended code.

  • Downloaded JavaScript code is constrained by the sand-box security model and can be relaxed for signed JavaScript.
