Unwanted Traffic Control via Hybrid Trust Management

At the same time as the Internet provides a lot of social value, it is bogged down by unwanted traffic, which is malicious, harmful or unexpected for its receiver. This paper proposes an unwanted traffic control solution through hybrid trust management. It can control unwanted traffic from its source to destinations according to trust evaluation at a Global Trust Operator and traffic and behavior analysis at hosts. Thus, it can support unwanted traffic control in both a distributed and centralized manner and in both a defensive and offensive way. Simulation based evaluation shows that the solution is effective with regard to botnet intrusion, malicious attack of ISP and DDoS intrusion via reflectors.
