Abstract
AbstractInternet service providers seek to increase revenue by reducing costs and increasing subscriptions. We take a systems security engineering approach to evaluate ways of enhancing customer modem cybersecurity, using a system dynamics model to show the impact of different solutions for improving customer modem bandwidth. The model is extensible and modifiable to test other stakeholder goals. We demonstrate this by modelling customer goodwill and solution cost. When used as a tool for planning system changes, the model can be compared to the live system before and during incremental system changes. This helps improve model validity, control risk, evaluate return on investment, and provide a platform for testing proposed system changes. Businesses with similar cyber vulnerabilities can benefit from using this system engineering approach.
