Mobile code in hosted applications allows the developer to add functionality and displays to hosted applications that are fluid, as opposed to a static web page. The data presentation becomes more appealing to the user, is easier to analyze, and navigation through the hosted application and data is much less complicated. Some mobile code technologies in use in today's applications are: Java, JavaScript, ActiveX, PDF, Postscript, Shockwave movies, Flash animations, and VBScript. The DoD has created policies that define the usage of mobile code on DoD systems. The usage restrictions and implementation guidance apply to both the selection and use of mobile code installed on organizational servers and mobile code downloaded and executed on individual workstations. The web server may host applications that contain mobile code and therefore, must meet the DoD-defined requirements regarding the deployment and/or use of mobile code. This includes digitally signing applets in order to provide a means for the client to establish application authenticity.

Check Text ( C-56589r2_chk )
Review the web server documentation and deployed configuration to determine whether mobile code used by hosted applications follows the DoD policies on the acquisition, development, and/or use of mobile code.

If the web server is not configured to follow the DoD policies on mobile code, this is a finding.
