I recently posted some new video’s to Tenable’s Youtube channel about how to visualize network attack and exploit paths in 3D. The videos are located on this playlist. They make use of data from Tenable’s Nessus and the Passive Vulnerability Scanner products to identify exploitable internet facing systems, exploitable internet browsing clients and exploitable clients that are trusted by servers. There is also a blog post and white paper on this sort of 3D analysis on the Tenable blog.
