Description
Java applets exist in both signed and unsigned forms. Although signed applets allow for authentication of the author in order to establish trust, even signed applets can potentially contain malware. Applet sources considered trusted will normally have their certificate information populated into the browser. This enables Java to validate applets against trusted sources automatically. Permitting users to grant execution permissions to Java applets signed by un-trusted authorities may result in malware executing on the system. This risks system confidentiality, integrity and availability.

If the system is on the SIPRNET, this requirement is NA. Navigate to the 'deployment.properties' file for Java. For 32 bit systems: C:\Program Files\Java\jre6\lib\deployment.properties For 64 bit systems you must check both the 64 bit and the 32 bit files: C:\Program Files\Java\jre6\lib\deployment.properties C:\Program Files (x86)\Java\jre6\lib\deployment.properties If the key 'deployment.security.askgrantdialog.notinca=false' is not present, this is a finding. If the key 'deployment.security.askgrantdialog.notinca' exists and is set to true, this is a finding.
