Abstract
Network awareness is a crucial aspect of network security, and is usually achieved through the use of active scanning. This method periodically introduces a large amount of traffic on the network, using up bandwidth. Much of the information obtained through active methods may also be obtained by passively listening to traffic. This document explains how passive scanning methods can aid in achieving network awareness without introducing unnecessary traffic, and documents a proof-of-concept tool to show how the methods presented might be implemented.
