  • MODELLING - elementary modelling through to sophisticated statistical analysis.

THREATS: I build threat models that give you the ability to identify a wide range of possible security threats, rate each one according to its potential to cause harm within your technical environment, and identify which should be the focus of your attention. 

This gives you a transparent way to get your technical subject matter experts working together to agree your top threats. Then, as your threat environment changes, which it will do all the time, you'll update your model and that will automatically refresh your list of top threats.

BUSINESS RISKS: I build business risk models that give you the ability to map and show the pathways by which security breaches affect your business operations and cause you business harm.


I help you assess each pathway in a way that exposes its significance for your business systems and operations. Then you can identify from the model which security breaches have the potential or tendency to cause your business the most harm. This will help you and your company’s business leaders agree what the Information Security function’s protection priorities should be. And it makes it easier for business leaders to see what they get in return for the support they give to you and your security team.


RISK POSTURE: I build risk posture models that give you the ability to assess the technical and non-technical controls protecting your business-critical systems against a wide range of threats.

You can then develop a dashboard view of each system's risk posture.

The controls can be your internal policies and standards or a recognised external standard such as ISO/IEC 27001 or the CSA’s CCM. Each system’s risk posture can be positioned against your business’ stated risk appetites so all concerned can see immediately whether that system’s risk posture is acceptable or not. Action plans can be devised and the effect of each plan on the risk posture calculated in advance so you can decide on the plan that will bring the system into acceptable compliance most cost-effectively. Multiple systems can be shown on the same display to show top management the company’s overall risk posture and to ensure top management attention gets directed to where it is most needed.
