Cyber Security

Examining the costs and causes of cyber incidents

“We believe the analysis provided in this article will be relevant in a number of ways to firms, policy makers, consumers, and particularly insurance companies. First, this research has uncovered an interesting paradox. On one hand, aggregate rates of cyber events and litigation both show similar trends – that they are more frequent and therefore potentially more expensive to organizations collecting and using personal information. In addition, the kinds of information being compromised (SSN, medical, and financial), are those that could well lead to more severe and longer lasting forms of consumer identity theft and fraud.

On the other hand, as we examine the actual costs of these events in our dataset (clearly one of the most important outcome measures), we find that they cost most firms less than $200k, only a fraction of the millions of dollars commonly cited. We also estimate that they represent only 0.4% of firm revenues, far less than other losses due to fraud, theft, corruption, or bad debt (Clearly, however, in some cases, data breaches and other cyberattacks have caused massive losses to firms, as well as some cases of identity theft do cause extreme harms to individuals. Note, however, that these discussions relate to average or median outcomes.).

Therefore, while we show an increase in the number of events and legal actions, our estimates of firm costs do not reflect the same magnitude of consequence, or urgency of attention. An important point can therefore be made concerning optimal investment in security. Given these relatively low costs (i.e. again, not every breach is a ‘Target’), it may be the case that firms are, indeed, engaging in a privately optimal level of security – that they are properly and efficiently managing cyber risks as they do with other forms of corporate risk. And that for most firms, because their expected losses are relatively low, they subsequently are investing in only a modest amount of data protection.

In addition, other research based on consumer surveys shows that 77% of respondents are very satisfied with firm responses to data breaches, and that only a small percentage (11%) of customers are lost due to attrition (Ablon et al. 2016). Therefore, while the potential for greater harm and losses appears to be increasing in time, evidence suggests that the actual financial impact to firms is considerably lower than expected. And so, if consumers are indeed mostly satisfied with firm responses from data breaches, and the costs from these events are relatively small, then firms may indeed lack a strong incentive to increase their investment in data security and privacy protection. If so, then voluntary adoption of the NIST Cybersecurity framework may prove very difficult and require additional motivation.

Therefore, where could the incentives originate? It is conceivable that the primary motivation may come from the cyber insurance industry through its use of incentive-based reductions in premiums (or deductibles). Indeed, with over 70 carriers offering cyber insurance policies (based on conversations between the author and Advisen representatives), and an estimated $2 billion in US premiums (Romanosky 2015), insurance companies may already be driving a de facto national cyber security practice across insureds. But while insurance companies do have an incentive to drive security investments, there is, as of yet, no evidence showing that firms are actually improving their posture in response to cyber insurance policies.”
