Description
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 malware running on the system, and risks system modification, invasion of privacy, or denial of service. Ensuring users cannot change the permission settings which control the execution of signed Java applets contributes to a more consistent security profile. NOTE: The 'JRE' directory in the file path may reflect the specific JRE release installed.
