  We present a comprehensive resilience glossary, comprising a set of 91
definitions of resilience-related terms used in the context of critical
infrastructures. The definition and use of many of these terms, as well as the
term resilience itself, shows an enormous variability in the literature.
Therefore, we draw from the diverse pool of published definitions, integrate
multiple contrasting views, compare the individual terms, and provide
references to adjoining or contesting views, to create a clear resilience
terminology. This terminology outlines a specific understanding of resilience
which supports the effective assessment and management of the resilience of
critical infrastructures. The two central elements of this understanding are
that (1) resilience is the ability of a system to deal with the impacts of
unspecific and possibly unforeseen disruptive events, and that (2) this ability
comprises three pillar capacities whose quality can be extracted from
performance curves.
