This paper presents an analytical model for optimal information security investment in threat controls and vulnerability reductions. The model quantifies the combined effect of security investments in addressing cyber threats and vulnerability, and derives the annual loss expectancy of the residual cyber risk – which represents the insurance premium for a full risk transfer. Based on the insights from the model, an improved cyber insurance design is proposed with more focus on risk advisory services and partnership. A case is made for insurance companies and IT security firms to jointly offer integrated risk mitigation and insurance protection services. This paper calls for collective spending by the private sector in pursuing cyber offenders and seeking loss recoveries, in collaboration with governments and law enforcement agencies.
