Managing business health in the presence of malicious attacks

View publication


Business metrics play a critical role in determining the best system-level configuration to achieve an organizational business-level goal. We present a framework for reasoning about business-level implications of malicious attacks affecting information technology (IT) systems that underlie various business processes. Through an exemplar web-based retail company scenario, we demonstrate how to quantify both the relative value of the individual business processes, and the relative cost to the business caused by breach of key security properties. The framework allows for mapping business-level metrics to IT system-level metrics, and uses a combination of those metrics to recommend optimal response actions and to guide recovery from security attacks. We validate the framework against three high-impact attack classes common in such web-based retail company situations. © 2011 IEEE.
