“…In [12], trust system placement is combined with network segmentation. A mixed-integer linear program (MILP) is used to partition a power system supervisory control and data acquisition (SCADA) network into a collection of enclaves such that a trust node is placed on at least one end of all arcs connecting different enclaves.…”

“…Constraint (24) enforces that a relay is compromised when the enclave that controls it has been accessed by the attacker. Constraints ( 23) and ( 24) contain bilinear terms that can be linearized using the same technique that linearizes (10) and (12). Constraints ( 25)-( 26) enforce that the line k is opened if and only if some relay that controls it is compromised.…”

Network segmentation of a power grid's communication system is one way to make the grid more resilient to cyber attacks. We develop a novel trilevel programming model to optimally segment a grid communication system, taking into account the actions of an information technolology (IT) administrator, attacker, and grid operator. The IT administrator is given an allowance to segment existing networks, and the attacker is given a fixed budget to attack the segmented communication system in an attempt to inflict damage on the grid. Finally, the grid operator is allowed to redispatch the grid after the attack in order to minimize damage. The resulting problem is a trilevel interdiction problem, which we solve by leveraging current research in bilevel branch and bound. We demonstrate the benefits of optimal network segmentation through case studies on the 9-bus WSCC system and the 30-bus IEEE system. These examples illustrate that network segmentation can significantly reduce the threat posed by a cyber attacker with perfect knowledge of the grid.
