Modeling Coupled Nonlinear Multilayered Dynamics: Cyber Attack and Disruption of an Electric Grid

Figure 1

The cyber system contains components that are uncompromised and vulnerable, uncompromised and currently invulnerable (hardened), compromised, and resetting (and thus temporarily unavailable system; metaphorically “in the shop”). A fraction of the cyber components (shown only for uncompromised and vulnerable components) are decoys that do not contribute to functionality of the physical system and are unable to co-compromise [20]. Dotted lines represent transitions from one stage to another and solid lines represent either external compromise or co-compromise.
