It is widely agreed that the Internet needs to become more resilient to a range of challenges that can seriously impact the normal operation of the network and networked services. Challenges include malicious attacks, misconfigurations, accidental faults and operational overloads. As part of an overall strategy for network resilience, a crucial requirement is the identification of challenges in real-time, followed by the application of appropriate remedial action. In this paper, we motivate and describe a new approach to challenge identification that goes beyond current techniques for attack, anomaly or fault detection. We describe a novel solution that uses policies to manage and orchestrate the interactions between various resilience mechanisms, which incrementally identify the nature of a challenge and deploys appropriate remediation mechanisms. We demonstrate the benefits of this approach via simulation of a resource starvation attack on an ISP infrastructure.
