This paper proposes a novel proxy network topology. The proposed network topology exhibits several attributes that strengthen the proxy network?s resistance to DoS attacks. Additionally, a novel reconfiguration algorithm for a class of proxy network topologies is proposed, and shown to decrease the topologies? vulnerability to DoS attacks. Proxy networks enable applications to communicate with users without disclosing their IP?s. An application?s resistance to DoS attacks is improved by hiding it behind a proxy network. We evaluate the proposed topology?s fault tolerance and its effectiveness in the resistance to DoS attacks.
