Management and Security WG

1. Management and Security WG Adya, Hubaux, Qiu, Rao, Simon, Wetherall

2. Outline • Problem Space • State of the Art • Research Challenges

3. Problem Space • Security • Classic security and privacy issues • Confidentiality, integrity, authentication • Denial of service • Restricting network access • Management • Accounting, provisioning, configuration • Fault diagnosis and repair

4. State of the Art • Classic security problems technologically solved but deployment lags • DoS is an open problem • Few or poor management tools • Do low-level data collection • Do minimal fault diagnosis Much of above applies to wired networks as well

5. Research Challenges Epsilon Management • How much can we reduce management? • Complete zero management infeasible • Incentives require management • Accounting, provisioning, configuration • E.g., Bootstrapping: what should the mesh box do • What is the charging model? What accounting data to collect?

6. Research Challenges Fault Diagnosis and Repair • What kind of faults to analyze? • Connectivity: why are you disconnected? • Performance: what is normal behavior? • Misconfiguration, broken equipment • How do you detect and fix these faults? • Tools to detect various fault and recover from them • How much can the network be self-healing?

7. Research Challenges Incentives for honest participation • Getting people to participate • Why should someone forward packets? • Detecting and punishing greedy behavior • Preventing protocol exploitation • Environmental tampering • Hardware tampering

8. Research Challenges Denial of service • Physical attacks unpreventable but local • How can you locate the responsible nodes • Network attacks • How much can you localize DoS attacks? • Rationing scarce bandwidth fairly

9. Predictions • Dan says • Administration and incentive overheads doom widespread deployment • Rest of us say • The world is not so gloomy!
