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

Figure 5

Dynamics of the cyber system and performance of the physical system when detection occurs at times drawn from the distribution in Figure 4(c), chosen to span most of the range of this distribution. The left hand column shows the number of uncompromised and vulnerable (black), uncompromised and temporarily hardened (blue), and compromised (green) cyber components as a function of time. The time of detection is denoted by a vertical dashed line. The right hand column shows performance of the physical system (black) and level of DCM (blue) as a function of time. As on the left, the vertical dotted line shows the time of detection.
