Title

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

Discussion

Certificates may be revoked due to improper issuance, compromise of the certificate, and failure to adhere to policy. Therefore, any certificate found revoked on a CRL or via Online Certificate Status Protocol (OCSP) 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. Ensuring users cannot change these settings assures a more consistent security profile.

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.locked' is not present in the deployment.properties file, this is a finding. If the key 'deployment.security.validation.ocsp.locked' is not present in the deployment.properties file, this is a finding.

Fix Text

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 the key 'deployment.security.validation.crl.locked' to the deployment.properties file. Add the key 'deployment.security.validation.ocsp.locked' to the deployment.properties file.
