Dependencies may be established between assets. Dependencies are used to propagate value (that is, security requirements) from valuable assets ‘above’ onto equipment assets ‘below’.
You may rate the system by domains or asset by asset. You select in Options / Valuation
If you are valuating by domains, you may skip dependencies, and jump directly into Valuation by domains
If you are valuating asset by asset, you have to establish the dependencies, and then jump into Valuation by assets

This screen is used to establish the dependencies between assets. The left panel shows the "father" assets (the asset above in the dependency graph), while the right panel shows the "children" assets (the assets below in the dependency graph).

To establish a dependency
- select F in the left panel (one or more assets)
- select S in the right panel (one or more assets)
- click on APPLY
If F or S, or both of then, are groups, the dependency will be established between the corresponding sons. So, when a group depends on another group, every asset from the father group depends on each asset of the son group.
To remove a dependency
- select F in the left panel (one or more assets)
- select S in the right panel (one or more assets)
- click on REMOVE
or
- select S in the left panel (one or more assets)
- click on REMOVE
To find out the sons of F
- select F in the left panel (one or more assets)
- click on SONS
To find out the fathers of S
- select S in the right panel (one or more assets)
- click on FATHERS
To set a degree of dependency
By default, dependencies are 100% on every dimension.
To set a degree between 0% and 100%:
- expand dependencies under an asset
- select the son asset
- click on the right button of the mouse Dependencies per dimension of security
To discover the dependency route from one asset to another
- select the father on the left panel
- select the son on the right panel
- click on PATH
