In article position of equilibrium and stability of system in case of bifurcation of system and making of a saltus on the unsteady operation mode is considered. Saltuses such (change of defining parameter of equilibrium of system) result in danger to functioning of system. The concept of function of danger is provided and models of physical security (abstract) system on the basis of the energy approach are considered. The sensitivity of the system to the external influence is estimated.
