Controls for Events Vulnerabilities can be viewed, added, and assigned to this page.
Here the controls are being assigned to one selected event given the threats/sources.
From the grid above, you can assign the potential controls to mitigate the vulnerabilities of the selected event "Late Train Running" given Threats/Sources.
You can select another event using the "Select an event:" dropdown:
Next to the index column is the "Control Name" column which lists all the controls for "Event Vulnerabilities" as rows.
The succeeding column headings correspond to the Sources Hierarchy of your Riskion model.
The intersecting cells given the controls (row) and the covering sources (column) are clickable. Clicking a cell will show a checkmark 
which means that the control is a potential control of the event given the source. Clicking the same cell will uncheck the cell.
From below, the control "Monitoring Gate System" is a potential control to reduce the vulnerability of the selected event "Late Train Running" given the source "Disregarding or Not Following Proper Policies, Processes, or Procedures". 
The dark gray cells (disabled) mean that the source is not contributing to the selected event (event is not vulnerable to the source), thus you will not be able to assign a control for it. This is true for the "Lack of Situational Awareness" source in our example. You can assign to which sources an event is vulnerable on the "Vulnerabilities Grid".
To add a new control to mitigate "Event Vulnerabilities, click the 
button.
Here you can specify the Control Name, Cost, and categories. The Control name is required, once you enter the control name the OK button will be enabled.
The added control will be displayed as a new row on the Controls column.
You can add multiple controls at once by pasting them from the clipboard.
You can see the format by hovering on the Paste controls button
Once you are ready, click "Paste controls".
