Messaging is a critical prerequisite for the scalability, dependability, and reliability of distributed services. A scalable messaging platform accommodates multiple diverse clients and adapts seamlessly within a heterogeneous environment. A reliable and dependable messaging scheme also offers a specific level of guarantee for the delivery of messages to legitimate services. Application services rely on message transport intermediaries to preserve loosely coupled message communication described as distributed communication services (DCS). DCS provides asynchronous and publish/subscribe communication for multiple dispersed services. Research in this area has exposed reliability and dependability problems with the publisher/subscriber architecture under denial of service (DoS) and/or distributed denial of service (DDoS) attacks. To support critical operations across distributed environments, the existing DCS paradigm needs to be extended to assure survivability against DoS/DDoS attacks.
