Cascade Damage Estimation Model for Internet Attacks

摘要

Risk analysis and damage estimation are inevitable studies to gain essential data for making a better decision in security investment. The most reasonable metrics to measure the damage of a security accident are recovery cost and business opportunity cost. In the case of a worm accident, the costs mean just the direct damage caused by infected systems. However, collaterally cascading damage is also serious damage which can impact on other innocent systems having depended on the infected systems for the purpose of processing their business or demanding some service.
