Abstract:
In this paper, a game-theoretical solution concept
is utilized to tackle the collusion attack in a SDN-based framework.
In our proposed setting, the defenders (i.e., switches) are
incentivized not to collude with the attackers in a repeated-game
setting that utilizes a reputation system. We first illustrate our
model and its components. We then use a socio-rational approach
to provide a new anti-collusion solution that shows cooperation
with the SDN controller is always Nash Equilibrium due to the
existence of a long-term utility function in our model.
