This article describes the method used to graph theory in security analysis. For the pursposes of this study, an environment is referred to here as a network of power lines and devices and a power grid is considered as a system of vertices which combine to make a network. Exploration of Fiedler´s theory will be applied herein to select the most important power lines for the entire network. Components related to these lines are logicly ordered and considered by the author´s modified analysis. This method has been improved and optimalized for risks related with illegal acts. Each power grid component has been connected with a variety of possible attacks and this device was gradually evaluated by five coefficients which takes values from 1 to 10. the level of risk was also assessed on the coefficient basis. In the last phase the most risky electricity network devices have been selected. Security measures have been proposed on the selected devices.

W artykule opisano wykorzystanie teori grafów w analizie zabezpieczeń. Opracowano model sieciowy z wykorzystaniem teorii Fiedlera. Każdy z elementów sieci połaczono z różnymi formami ataku i opisano odpowiednimi współczynnikami. Na tej podstawie wybrano najbardziej ryzykowny wariant.
