Discussion

Configuring the application to implement organization-wide security implementation guides and security checklists ensures compliance with federal standards and establishes a common security baseline across DoD that reflects the most restrictive security posture consistent with operational requirements. Configuration settings are the set of parameters that can be changed that affect the security posture and/or functionality of the system. Security-related parameters are those parameters impacting the security state of the application, including the parameters required to satisfy other security control requirements.

Check Content

On the Horizon Connection Server, launch the Registry Editor. Traverse the registry tree to "HKLM\Software\VMware, Inc.\VMware VDM\Plugins\wsnm\TunnelService\Params". Locate the "JvmOptions" key.

If "JvmOptions" does not exist, or the path does not exist, this is NOT a finding.

If "JvmOptions" does not include the "-Djdk.tls.rejectClientInitiatedRenegotiation=true" option, this is a finding.
