Title

The option to enable online certificate validation must be enabled. (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.

Check Content

If the system is on the SIPRNET, this requirement is NA. Navigate to the 'deployment.properties' file for Java. For 32 bit systems: C:\Program Files\Java\jre6\lib\deployment.properties. For 64 bit systems you must check both the 64 bit and the 32 bit files: C:\Program Files\Java\jre6\lib\deployment.properties C:\Program Files (x86)\Java\jre6\lib\deployment.properties If the key 'deployment.security.validation.ocsp' is not present in the deployment.properties file, this is a finding. If the key 'deployment.security.validation.ocsp' is set to 'false', this is a finding.

Fix Text

Enable the 'Enable online certificate validation' option. Navigate to the 'deployment.properties' file for Java. For 32 bit systems: C:\Program Files\Java\jre6\lib\deployment.properties. For 64 bit systems you must check both the 64 bit and the 32 bit files: C:\Program Files\Java\jre6\lib\deployment.properties C:\Program Files (x86)\Java\jre6\lib\deployment.properties Add or update the key 'deployment.security.validation.ocsp' in the deployment.properties file. Set the value to 'true'.
