Trust-based collaborative defences in multi network alliances

Collaborative defences against, for example, Distributed Denial of Service attacks require trust between the collaborators. Even in a trusted alliance of collaborators, some members are more trusted than others with the execution of a specific task. This paper shows that trust can be used as a criterion in collaborative defences against attacks on computer infrastructures. We evaluate the implementation of a trust based defence in an overlay network and compare its' performance to other collaborative defences in the same environment. Results show that the trust-based defence has comparable results to the other collaborative defences after the trust values converge to reflect the behaviour of the nodes.
