The price of cyber (in)security: evidence from the Italian private sector

No 407, Questioni di Economia e Finanza (Occasional Papers) from Bank of Italy, Economic Research and International Relations Area

Abstract: This paper presents evidence on the economic dimension of cyber risk in the Italian private non-financial sector, based on Bank of Italy survey data. In 2016, the median amount spent on preventing cyber attacks was a modest �4,530, i.e. 15 per cent of a typical worker�s annual gross wages. A wide variation exists across sectors and size classes, reflecting differences in how appealing a target a firm is to attackers and firms� awareness of threats: median values range from �3,120 for small firms to �19,080 in the ICT sector and �44,590 for large firms. The market for cyber defence in our reference universe is worth at least �570 million. Having been attacked in the past proves to be a strong incentive to invest in security. The majority of breached firms suffered damages worth less than �10,000; 0.1 per cent reported costs of at least �200,000. Neither the sampling design nor the questionnaire were geared towards the measurement of tail events: underestimation of large incidents is likely. More information is needed before the economy-wide cost can be estimated.
