Top 5 objections to using quantitative models within cyber risk management
Changing habits and mindsets take time and persistence. Especially within IT risk management. Again and again, we at ACI meet tonnes of objections to changing behaviour despite witnessing the benefits of moving from qualitative to quantitative. So, I felt...
Managing Cyber Risk With Tactical and Strategic Management Information

The art of producing a 90% confidence interval using decomposition and calibration
When speaking about future events, it's inherently subject to uncertainty. A risk assessment tries to understand future loss events and is therefore also subject to uncertainty. The less history or fewer measurements, the greater the uncertainty. How can one predict...
