Abstract
Systems and methods are provided for mitigating security attacks by enabling collaboration between security service functions. A Service Function Chaining (SFC) node receives a packet and determines whether to apply a service function to the packet. Responsive to determining that the packet has been treated by the service function, the packet can be reclassified and switched to a different SFC path.
