Title
Choosing Protection: User Investments In Security Measures For Cyber Risk Management
Abstract
Firewalls, Intrusion Detection Systems (IDS), and cyber-insurance are widely used to protect against cyber-attacks and their consequences. The optimal investment in each of these security measures depends on the likelihood of threats and the severity of the damage they cause, on the user's ability to distinguish between malicious and non-malicious content, and on the properties of the different security measures and their costs. We present a model of the optimal investment in the security measures, given that the effectiveness of each measure depends partly on the performance of the others. We also conducted an online experiment in which participants classified events as malicious or non-malicious, based on the value of an observed variable. They could protect themselves by investing in a firewall, an IDS or insurance. Four experimental conditions differed in the optimal investment in the different measures. Participants tended to invest preferably in the IDS, irrespective of the benefits from this investment. They were able to identify the firewall and insurance conditions in which investments were beneficial, but they did not invest optimally in these measures. The results imply that users' intuitive decisions to invest resources in risk management measures are likely to be non-optimal. It is important to develop methods to help users in their decisions.
