Explore the Siphon Project, a passive network mapping technique, in this Black Hat USA 2001 conference talk by Marshall Beddoe and Chris Abad. Delve into the importance of network mapping and compare active and passive mapping methods. Learn about various mapping techniques, including port mapping, operating system identification, topology mapping, and vulnerability assessment. Discover the challenges and solutions in passive network mapping, such as TCP and UDP port mapping, OS identification, and information enumeration. Gain insights into routing protocols like RIP and OSPF for topology mapping, and understand the process of converting distance vector to link state routing. Examine traffic analysis techniques and view an example Siphon report to grasp the practical applications of this innovative approach to network security.
