Interdependencies of systems and components are analyzed so as
to determine indirect effects and attack weak points upon which strong
points depend. Examples include attacking medical information systems in
order to disrupt armed forces deployments, attacking the supply chain in
order to corrupt information within an organization, and attacking power
grid elements in order to disrupt financial systems.
analysis of dependencies appears to require substantial detailed knowledge of
an operation or similar operations. Finding common critical dependencies
appears to be straightforward, but producing desired and controllable
effects may be more complex. Mathematical analysis of this issue has not
been published to date. Common mode faults and systemic flaws are of
particular utility in this sort of attack.
