Check Text (C-223780r991593_chk)
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 (F-25441r515029_fix)
Develop a policy application and policy agent to employ a deny-all, allow-by-exception firewall policy for allowing connections to other systems.
