Abstract:
Embodiments of the present disclosure relate to method and device for providing a security service. For example, a method comprises: in response to receiving, at a first controller, a first request to create a first service chain for an application in a network, obtaining configuration information associated with the security service from the first request; generating, based on the configuration information, a second request to create a sequence of security functions associated with the first service chain; sending the second request to a second controller so as to create the sequence of security functions in the network; and in response to receiving from the second controller an acknowledgement for the sequence of security functions, creating the first service chain based on the sequence of security functions. Embodiments of the present disclosure further provide a device capable of implementing the above method.
