Official European Definition
One of the most cited definitions of interdependency is the one by Rinaldi et al. who define interedependency as a bidirectional relationship between two infrastructures through which the state of each infrastructure influences or is correlated to the state of the other [1]. This definition is adopted on the Commission's staff working document on a new approach to the EPCIP [2]. Interdependencies can be identified "between critical infrastructures, industry, and state actors". The working document also highlights that threats to a single Critical infrastructure can have "a very significant impact on a broad range of actors in different infrastructures and more widely". The document also highlight the cross-border effect of interdependencies, spanning a number of European countries. The example identified in the document is the European high-voltage electricity grid, composed of the interconnected national high-voltage electricity grids.
National Definitions
USA
Mutually reliant relationship between entities (objects, individuals, or groups) [3]. The degree of interdependency does not need to be equal in both directions. For example, the Energy Sector depends on a functioning Water Sector for successful day-to-day operations, just as the Water Sector needs energy to effectively manage water and wastewater systems [4].
Germany
Interdependency is the complete or partial mutual dependency of several goods or services [5].
