Network vulnerability in two-phase evolution

Contrary to traditional evolutionary models of complex networks a novel consideration with two-formation & degradation - phases has been proposed. To clarify which of the stages of the phases are more sensible the evolving network has been put to simulated attacks. A novel integral vulnerability metrics has been proposed which demonstrated strong dependence on the network growth rate of the stage put under short time attacks. It was found that the higher the rate is the higher pertinent vulnerability is observed. The study gives a dynamic scope for future analysis of network security, hints to build resilient network systems, and ways to perform network management effectively.
