  1. RB WhitakerCS 6100 10 December 2008 Dealing with trust issues in a multi-agent Intrusion prevention system

  2. IPS and MAS Comparisons IPS Features Run without human supervision Recover from failures Monitors itself Minimal overhead while running Match different security policies Adapt to changes in the system Scalable to multiple hosts Degradation of service Dynamically configurable Determine course of action for response Determine course of action for future prevention Capable of performing a determined course of action MAS Features Autonomy Proactivity Reactivity Social Ability

  3. The Basic System • Agents are responsible for specific components • Agents make judgements about the safety of the current situation • Agents work with other agents • Request for information about a state • Assemble collected information • Factor in what agent currently knows • Handle other agents’ state requests

  4. The Trust Problem • How has trust been dealt with in the past? • What happens when an agent becomes compromised?

  5. The Solution • You can trust yourself • You can’t trust anyone • You cantrust everyone • Develop a set or correspondence agents

  6. Experiments • Optimal configuration of correspondence set size • Comparison to other trust models • Comparison to existing Intrusion Detection Systems

  7. Determining an Optimal Configuration

  8. Comparison to Other Trust Models

  9. Comparison to other IDS’s

  10. Conclusions & Future Work • Group-based trust is a more effective approach in an IPS setting • Competitive with existing IDS systems • Can be applied to other areas of MAS
