| Online certificate validation provides a real-time alternative to validating a certificate. When enabled, if a certificate is presented, the status of the certificate is requested. The status is sent back as 'current', 'expired', or 'unknown'. Online certificate validation provides a greater degree of validation of certificates when running a signed Java applet. Permitting execution of an applet with an invalid certificate may result in malware, system modification, invasion of privacy, and denial of service.
Ensuring users cannot change settings, contributes to a more consistent security profile.
