Risk Management and Risk Ranking.




Has your organization performed a Risk Assessment? 

Many organizations fail to keep current on Risk Management. Often times risk management is only important after a costly incident occurs. With little effort it’s easy to reduce your organizations risk exposure by performing a Risk Assessment.  A risk assessment or risk analysis is a simple process of identifying the most values assets, assigning a value to them, and then identifying the probability of certain threat occurring. Once you have an inventory of assets in place and have identified the most likely threats then you simply calculate a risk ranking. The higher the risk ranking the more time, money, and effort is needed on risk mitigation steps to prevent loses from occurring.

 Here’s a simple and valuable formula that your organization can use to identify and rank risks to your organization.

Risk Ranking = (the likelihood of a vulnerability occurring) X (Value of the Asset) – (the percentage of risk mitigation controls) + (the uncertainty of knowledge of the vulnerability)



For example:
Let’s say that you have an Application Server that is used by most of your workers and you also have a separate email server that your workers use too. How do you determine which one has the most risk to the organization?

Asset
Asset Impact
Vulnerability
Vulnerability Likelihood
Certainty of assumptions
Risk Mitigation
Risk Rating Factor
Application Server
50
Hardware failure
1
.9
0
=55
Mail Server
100
Hardware failure
.5
.8
.50
=35

You can see from this chart that the greatest risk is associated with the Application Server. You can also see that unlike the mail server there is no risk mitigation associated with the application server. The conclusion is very simple; the organizations should spend effort on risk mitigation for the Application server because the risk ranking is the highest.
