Title

The option to enable online certificate validation must be locked. (Cat II impact)

Discussion

Online certificate validation provides a real-time option to validate 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. NOTE: The 'JRE' directory in the file path may reflect the specific JRE release installed.
