Abstract
Embodiments of the present disclosure relate to methods, devices and computer readable storage medium for tracing an attack source in a service function chain overlay network. In example embodiments, a request for tracing an attack source of an attacking data is sent at the attack tracer to a first service function chain domain of a plurality of service function chain domains through which the attacking data flow passes subsequently. The request includes flow characteristics of the attacking data flow. Then, the attack tracer receives a first set of results of flow matching based on the flow characteristics from the first service function chain domain. The attack tracer identifies the attack source in the plurality of service function chain domains at least in part based on the first set of results. In this way, the attack source may be traced efficiently in the service function chain overlay network.
