Risk Assessment in Critical Infrastructure Security Modelling Based on Dependency Analysis (Short Paper)

摘要

Critical infrastructure (CI) services are consumed by the society constantly and we expect them to be available 24 hours a day. CIs can be mutually dependent on each other and a failure in one infrastructure can cascade to another interdependent infrastructure to cause service disruptions. Methods to better assess and monitor CIs and their interdependencies in order to predict possible risks have to be developed. In this work, we present a method for CI analysis to identify critical entities in CIs at a management/organisational level as well as at a technical level supported by the PROTOS-MATINE model for dependency analysis.
