Across the United States, 3200 separate organizations own and operate electrical infrastructure. The widely dispersed nature of the nation’s electrical grid and associated control systems has a number of advantages, including a reduced risk that any single accident or attack could create a widespread failure from which it might take weeks to recover. Since the late 1990’s, however, cost pressures have driven the integration of conventional information technologies into these independent industrial control systems, resulting in a grid that is increasingly vulnerable to cyber-attack, either through direct connection to the Internet or via direct interfaces to utility IT systems.
Modern-day software operates within a complex ecosystem of libraries, models, protocols and devices. Ecosystems change over time in response to new technologies or paradigms, as a consequence of repairing discovered vulnerabilities (security, logical, or performance-related), or because of varying resource availability and reconfiguration of the underlying execution platform. When these changes occur, applications may no longer work as expected because their assumptions on how the ecosystem should behave may have been inadvertently violated.
