Abstract

Networked systems are subject to a wide range of challenges whose nature changes over time, including malicious attacks and operational overload. Numerous mechanisms can be used to ensure the resilience of networked systems, but it can be difficult to define how these mechanisms should be configured in networks that support many services that have differing and shifting requirements. In this paper, we explore the potential benefits of using policies for defining the configuration of mechanisms for resilience. We discuss some of the difficulties of defining configurations, such as identifying conflicts, and highlight how existing policy frameworks could be used or extended to manage this complexity.
