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!
