Abstract
Information and Communication Technology (ICT) is increasingly
utilised in the electrical power transmission system. For the
power system, ICT brings a lot of benefits, but it also introduces new
types of vulnerabilities and threats. Currently the interdependencies between
the power and ICT system are not fully understood, including
how threats (both malicious and accidental) towards the ICT system
may impact on power delivery. This paper addresses the need for improved
understanding between ICT security and power experts. It explains
important terms used differently in the two disciplines, identifies
main impacts on power systems that may result from ICT incidents, and
proposes a set of indicators that can be used as a basis for selecting
measures. Copyright IFIP International Federation for Information Processing 2013
