Proper Incentives for Proper IT Security Management - A System Dynamics Approach

It has been known for many years that security failures are caused at least as often by bad incentives as by bad design. However, the regulatory correction of bad incentives is not easy in practice and it is still lacking. In the meantime, system dynamics models of security systems can improve the situation by increasing the awareness that misaligned incentives can backfire as long-term consequences of security failures hit back the principal. We illustrate our argument using system archetypes and concept simulation models revealing the impact of two different security strategies, viz. misaligned incentives (the customer having the burden of proof in case of alleged fraud) vs the bank having the burden of proof. From this we argue that online system dynamics could be used in eGovernment to educate principals and the public. Also, legal measures could become more effective when supported with forensic evidence from simulation models.
