Verify that the built-in firewall is enabled: # /usr/sbin/system_profiler SPConfigurationProfileDataType | /usr/bin/grep 'EnableFirewall\|EnableStealthMode' If the return is not "EnableFirewall = 1;" and "EnableStealthMode = 1;" this is a finding. If the built-in firewall is not enabled, ask the System Administrator if another application firewall is installed and enabled. If no application firewall is installed and enabled, this is a finding. |
