Abstract
A method for processing a network service supported by a network infrastructure allowing virtualization of network functions. The network service is made up of a sequence, called an initial sequence, of at least one virtualized network function processing an incoming stream. The method includes: detecting an anomaly relating to the at least one virtualized network function; on the basis of the anomaly, detecting and identifying a network attack targeting the network service; identifying, in the initial sequence, at least one virtualized network function impacted by the attack; modifying the initial sequence so as to circumscribe the attack in such a way that the incoming stream is routed towards at least one virtualized network function, called the curative function, carrying out a processing of the incoming stream, called the malicious stream, as well as of functions implemented by the at least one virtualized network function impacted by the attack.
