Title

The dialog to enable users to check publisher certificates for revocation must be enabled. (Cat II impact)

Discussion

A certificate revocation list is a directory which contains a list of certificates that have been revoked for various reasons. Certificates may be revoked due to improper issuance, compromise of the certificate, and failure to adhere to policy. Therefore, any certificate found on a CRL should not be trusted. Permitting execution of an applet published with a revoked certificate may result in spoofing, 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.crl' is not present in the deployment.properties file, this is a finding. If the key 'deployment.security.validation.crl' is set to 'false', this is a finding.

Fix Text

If the system is on the SIPRNET, this requirement is NA. Enable the 'Check certificates for revocation using Certificate Revocation Lists (CRL)' 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.crl' in the deployment.properties file. Set the value to 'true'.
