Interdependency
The terms interdependency and dependency are often used in the CIP literature as synonymous. See also dependency.
One of the most cited definitions of interdependency is the one by Rinaldi et al. who define interdependency as a

The CIPRNet project [3] uses the following definition:

Interdependence: dependency relationship or interference of a critical infrastructure with another, or of a Critical Infrastructure priority area with another.

The degree of interdependence does not need to be equal in both directions.
United States
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 [10].
Discussion
Empirical analysis of Critical infrastructure incidents and events by Van Eeten et al. shows that interdependencies (= the mutual Dependency) hardly occur; and when they occur the effect is at a lower (weaker) dependency level.
