We develop a method that substantially improves the robustness of complex networks against malicious attacks. This technique is successfully applied for the Internet at the level of autonomous system and other scale-free networks. As malicious attack we choose the dynamic degree-based attack and we numerically optimize the network under the condition that the degree distribution remains invariant. We also study three different types of scale-free network models and compare the results with the real network.
