Discussion

Configuration settings are the set of parameters that can be changed in hardware, software, or firmware components of the system that affect the security posture and/or functionality of the system. Security-related parameters are those parameters impacting the security state of the system, including the parameters required to satisfy other security control requirements. Security-related parameters include, for example: registry settings; account, file, directory permission settings; and settings for functions, ports, protocols, services, and remote connections.

Check Content

Examine the policy agent policy statements. If it can be determined that the policy agent employs a deny-all, allow-by exception firewall policy for allowing connections to other systems this is not a finding.

Fix Text

Develop a policy application and policy agent to employ a deny-all, allow-by-exception firewall policy for allowing connections to other systems.
