We divide the study of economic impact of DDoS attacks into five components:
C1 Recognise the stakeholders of DDoS attacks. C2 Study attacker motives. C3 Analyse and measure the indirect losses to the victim. C4 Analyse the direct losses to the victim. C5 Build a model for businesses to chose the correct protection strategy. For each of these components we use publicly available data (Google alerts and OpenIntel) to conduct the analysis. In this talk I would be able to present the finalised results of two of my studies.
