Electric power grids, vascular networks in leaves and neuronal networks in the human brain are examples of complex networks which are subject to fluctuations. Local changes in the underlying dynamics may affect the whole network and, in the worst case, cause a total collapse of the system through a cascading failure. However, certain network motifs exist, which effectively decouple different network modules and thus reduce failure spreading drastically, or even inhibit it completely. In this contribution we review the function of network isolator motifs for linear flow networks and investigate their operation for non-linear network dynamical systems, such as Kuramoto networks. We demonstrate how these network motifs can hide the source of a perturbation and discuss how they may be applied to improve the robustness of different types of networks.
