Cyber Security Leadership and Risk Management - How to Achieve Resiliency in the Face of Escalating Threats.


The state of an organisation’s IT security posture is too important to be fully delegated to the CIO and CISO. A serious cyber attack can have a material adverse effect on an organisation’s well being, financially and otherwise. This places cyber security into the category of a business risk that warrants CEO and Board attention. Getting the Board of Directors engaged and identifying key metrics to operationalise the needed risk and resource decisions will minimise successful attacks and achieve mission resiliency.

As organisations evolve their security posture, two key metrics for measuring their security capabilities are its Mean-Time-to-Detect (MTTD) threats that present an actual risk and its Mean-Time-to-Respond (MTTR) to fully analyse the threat and mitigate any risk presented. Each organisation needs to assess for itself the appropriate level of maturity based on its own risk tolerances and establish a robust cyber security scorecard to drive successful operations.
