Abstract: This paper aims at studying information attacks and related financial losses by assessing risks from these attacks. Firstly, a computational model on risk assessment is developed. A comparison study of information attacks in the USA and the UK is then conducted based on this model. Secondly, risk assessment is performed on attacks on the information systems and resulting financial losses in the USA based on growth indices and growth rates of risk assessments. Finally, correlation analysis is conducted to analyse relationships between attacks and financial losses in the USA. The study will help people to understand better how severe the current threat on computer information system is and which attack types cause more financial losses. The developed computational model can be used to assess risks for different attack types, and gauge relative risks introduced by each attack.
