Modifying flow rule attack is a type of attack against controllers in SDN, leading to severe influence on network. In this paper, we propose Mcad-SA, an aware decision-making security architecture with multi-controller, to deal with it. It schedules the controllers in a dynamic and random way and adopts the vote results from the majority of controllers to determine valid flow rules. Theory analysis proves its validity.
