Abstract

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. The European FP7 ResumeNet project is exploring a holistic strategy for enhancing the resilience of future networks to such challenges. A crucial part of this strategy involves detection of challenges in real-time followed by appropriate remedial action. This requires appropriate identification of challenges. In this talk I will motivate and describe a new approach to challenge identification that goes beyond current techniques for attack, anomaly or fault detection. I describe a novel solution that uses policies to manage and orchestrate the interactions between various resilience mechanisms, which incrementally identifies the nature of a challenge and deploys appropriate remediation mechanisms. This is illustrated via simulation of a resource starvation attack on an ISP infrastructure. I finish the talk by briefly considering what is becoming the most widespread and pernicious challenge on the Internet: botnets.
