3.2 INCIDENTS INVOLVING EACH THREAT

Each Incident is defined as triple of the form <threat, loss category, asset category>. By doing things this way it is possible to separate the various forms of loss that a given threat may cause to the enterprise as the result of acting on the same asset category.

The sections below look at each threat and indicate the various incidents that were associated with it in the analysis. For each incident, a table is presented (FIGURES 13.1, 13.2, ...) indicating its SLE and ALE (where the ALE is generated by multiplying the SLE for the incident by the AFE of the threat). The overall ALE for a threat is the sum of the ALEs for each of the associated incidents. This is shown as the total of the third column. The percentage of this total represented by the ALE for each incident is indicated in the fourth column.

Also shown for each threat is a barchart that provides a visual presentation of the relative magnitudes of the ALE for each incident. These are shown as FIGURES 14.1, 14.2, ....

Piecharts are then also provided that indicate the percentage of each threat ALE that is accounted for by each incident that is used in its calculation.
