JRE0010-J72K7- The dialog enabling users to grant permissions to execute signed content from an un-trusted authority must be locked.

Information

Java applets exist both signed and unsigned. Even for signed applets, there can be many sources, some of which may be purveyors of malware. Applet sources considered trusted can have their information populated into the browser, enabling Java to validate applets against trusted sources. Permitting execution of signed Java applets from un-trusted sources may result in acquiring malware, and risks system modification, invasion of privacy, or denial of service. Ensuring users cannot change settings contributes to a more consistent security profile.

Solution

Lock the 'Allow user to grant permissions to content from an un-trusted authority' feature.

Navigate to the 'deployment.properties' file for Java.

For 32 bit systems:
C:\Program Files\Java\jre7\lib\deployment.properties.

For 64 bit systems you must check both the 64 bit and the 32 bit files:
C:\Program Files\Java\jre7\lib\deployment.properties
C:\Program Files (x86)\Java\jre7\lib\deployment.properties


Add the key 'deployment.security.askgrantdialog.notinca.locked' to the deployment.properties file.
