('binary' encoding is not supported, stored as-is) Due to the lack of statistical skills the figures are a guess and all that occurs is a qualitative result rather then a quantitative one.

The real example of a quantitative risk assessment is to create a Bayesian prior based on the figures from the firm, an industry trend and other data. Trend data for malware can be formulated using a heteroscadestic trending of the time series data for infections coupled with a fragility / survival algorithm.=20

The issue is that although an extremely accurate risk profile can be developed, is that it is:
1 Costly
2 Few people will know what I am referring to let alone be able to
do this.

Hence, we end up with qualitative risk approximates and risk analysis remains an art rather then developing into a science.=20
