Lock the Risk Matrix

You can configure ACA to allow users to assign risk values to Asset Criticality Analysis System, Equipment, and Functional Location records using fields defined for the Asset Criticality Analysis System family. To do so, you will need to specify which Asset Criticality Analysis System fields will accept the risk values. You can optionally add these fields to the Asset Criticality Analysis System datasheet. If you add the fields to the datasheet, users will be able to specify risk values in those fields within ACA. If you do not add these fields to the datasheet, however, users will need to map values to them by importing the values from a Microsoft Excel file (when creating new analyses or updating risk values in existing analyses). After an Asset Criticality Analysis System record is saved with risk values in the specified fields, the appropriate Risk Assessment and Risk Rank records will be created automatically using the specified values. In the Risk Matrix, each section will contain the specified probability, consequence, and protection level. In addition, users will not be able to select a different probability, consequence, or protection level using the Risk Matrix. In other words, these properties of the Risk Matrix will be locked down.

In other words, you might lock the probability and the consequence, only the probability, only the consequence, and so on. For any property that is locked, the corresponding item on the Risk Matrix will be disabled. For example, if you lock only the probability, when a user accesses the Risk Matrix, he will be able to select a consequence but not a probability. The probability must be set from the selected field in the Asset Criticality Analysis System family.
