  1. Using Topological Mapping to Manage & Secure Large NetworksNANOG23: October 23, 2001karl@lumeta.com

  2. Lumeta: What we do • Connect to a client network, send and receive lots of packets, and deliver maps and data • It all started with mapping the Internet...

  3. The Internet

  4. Why is this Important? • Images convey more information in less “real estate.” • Maps call attention to anomalies more clearly. • You can’t secure what you can’t manage. You can’t manage what you can’t define.

  5. A Typical Intranet

  6. Specifics for ISPs • Order Matters: For an ISP, the network is their business • The business portions of ISP networks are highly organized and methodically laid out • Yet, there are still organic components, e.g., the corporate intranet

  7. What an ISP Looks Like

  8. What can be Found? • Undocumented infrastructure or incomplete mergers • Legacy connections to forgotten business partners or spun off business units • Mismanaged firewalls and routers

  9. Routing Table Errors

  10. Incomplete Divestitures

  11. Another Look at the ISP

  12. Conclusion • Network maps condense complex structural information into a manageable form • Topological features can readily point out anomalies • Assertion: Any large network can be improved by being mapped
