System and method for analyzing a router in a shared network system

A system and method for analyzing a router in a shared network system (SNS). Specifically, the present invention retrieves information for each network participating in the SNS from a common router. By identifying source and destination networks for communications in the SNS, and then comparing the identified networks to network policies, a network map, and/or flow tables, security findings for each network can be identified. These findings, as well as the network map, can then be outputted to each network according to their preferences in a report or summary format.
