Handbook on Resilience of Socio-Technical Systems

Edited by Matthias Ruth and Stefan Goessling-Reisemann

The goal to improve the resilience of social systems – communities and their economies – is increasingly adopted by decision makers. This unique and comprehensive Handbook focuses on the interdependencies of these social systems and the technologies that support them. Special attention is given to the ways in which resilience is conceptualized by different disciplines, how resilience may be assessed, and how resilience strategies are implemented. Case illustrations are presented throughout to aid understanding.

Chapter 17: IT security for functional resilience in energy systems: effect-centric IT security

Lars Fischer and Sebastian Lehnhoff

Abstract

From the point of view of energy system operators, cyberattacks, that is, information technology (IT)-security incidents, comprise an additional source for reduced functionality or system failure. In this capability cyberattacks ‘compete’ with unintentional disturbances like weather, natural disasters and accidental disruptions. Information technology-security experts, developing countermeasures to cyberattacks, primarily are concerned with intelligent, complex, malicious attacks that must be defended against using dedicated countermeasures and security processes. In order to prevent degraded function of energy systems through intentional attacks, for example, effecting a blackout or instabilities, functional resilience of the energy system is mandatory.
