Abstract-Distributed denial-of-service (DDoS) attacks continue to trouble network operators and service providers, and with increasing intensity. Effective response to DDoS can be slow (because of manual diagnosis and interaction) and potentially self-defeating (as indiscriminate filtering accomplishes a likely goal of the attacker), and this is the result of the discrepancy between the service provider's flow-based, application-level view of traffic and the network operator's packet-based, network-level view and limited functionality. Furthermore, a network required to take action may be in an autonomous system (AS) several AShops away from the service, so it has no direct relationship with the service on whose behalf it acts. This paper presents Antidose, a means of interaction between a vulnerable peripheral service and an indirectly related AS that allows the AS to confidently deploy local filtering with discrimination under the control of the remote service. We implement the core filtering mechanism of antidose, and provide an analysis of it to demonstrate that conscious attacks against the mechanism will not expose the AS to additional attacks. We present a performance evaluation to show that the mechanism is operationally feasible in the emerging trend of operators' willingness to increase the programmability of their hardware with SDN technologies such as OpenFlow, as well as to act to mitigate attacks on downstream customers.
Antidose system REF presents a means of interaction between a vulnerable peripheral service and an indirectly related Autonomous System (AS), which allows the AS to confidently deploy local filtering rules under the control of the remote service.
