Also, another arrow adjacent to the destination port number pointing toward the firewall is displayed to indicate that a communication is permitted to the destination port number. The destination port number and the other arrow are located between an icon for the network and an icon for the firewall. A table including definitions of a plurality of rules is generated and displayed. Each of the definitions includes entries for a source IP address and destination IP address of a permitted but vulnerable data flow. The source IP address and destination IP address entries are color coded to indicate security levels of respective source and destination networks. Another table includes definitions of a misconfigured data flow, and entries for a source IP address and destination IP address of the misconfigured data flow. The source IP address and destination IP address are color coded to indicate security levels of respective source network and destination network.
