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. The setting must be locked so users cannot change the setting. Ensuring users cannot change settings contributes to a more consistent security profile.
