Seminar Title: A Structural Model of Cyber Risk Aggregate Loss Distribution of Medium Size Enterprises

19 July 2018 – RiskLab Event: Seminar and drinks/finger food


In a corporate and/or government domain, a cyber risk can be seen as a risk of a financial loss due to a breach of an institution’s IT infrastructure by unauthorized parties and the ex- ploitation, taking possession of, or disclosure of data assets, thus creating financial and/or reputational damage.

During this seminar we propose a structural model of aggregate loss distribution for the cyber risk of medium-size enterprise. To our knowledge, no theoretical model of aggregate loss distri- bution for cyber risk exists in this setting. To achieve this, we contextualize the problem in the probabilistic graph-theoretical framework, assuming the IT network topology to be represented by an appropriate (random) graph of finite (or infinite) size. We allow for heteroge- neous node vulnerability and loss topology, and discuss the characteristic examples. Contagion is modelled using the framework of percolation theory.
