Cyber Security Resilience & Risk Aggregation concepts have a near relationship because Risk aggregation refers to efforts done by firms to develop quantitative risk measures that incorporate multiple types or sources of risk.
Cyber Security Resilience is the capacity to have different Cyber controls which can provide the organization an adequate resilience according the organization risk appetite by doing risk management of the aggregation of multiple types or sources of risk.
One interesting topic is Internet of Things (IoT) which is increasing in our personal and professional life. The more assets are “shared” (including Critical Infrastructures and Smart Cities IT assets) the more risk we are assuming in our organization. All these risk is added using Risk Aggregation, so more effort we will need to do to improve our security to get an adequate Cyber Security Resilience level.
I created a presentation where I explain in details this topic, you can see my presentation here:
