Everyone with IT system authorization in a company represents a security risk for that company. For example, an identity with permission to edit financial data in SAP carries a higher risk than an identity with permission to edit their own main data. To quantify the risk, you can enter a risk value for every company resource in One Identity Manager. A risk index is calculated from this value for every identity that has this company resource assigned to it directly or indirectly. Company resources include target system entitlements (for example, Active Directory groups or SAP profiles), system roles, subscribable reports, software, and resources. In this way, all the people that represent a particular risk to the company can be found.
In the context of Identity Audit, compliance rules can also be given a risk index. With each rule violation, the security risk of all identities that violate the rule may increase. Therefore, these risk indexes are also included in the identities' risk calculation. You can define appropriate countermeasures through mitigating controls, and store them with the compliance rules.
Other factors can influence the calculation of identities' risk indexes. These include: the type of resource assignment (approved request or direct assignment), attestations, exception approvals for rule violations, identities' responsibilities, and defined weightings. Furthermore, the risk index can be calculated for all business roles, organizations, and system roles that have company resources assigned to them. The user account risk index is calculated based on the system entitlements assigned.
Based on the risk index history, resulting risk indexes are calculated for employees, user accounts, and hierarchical roles. All direct and indirectly assigned objects are taken into account.
One Identity Manager provides default risk index functions for risk indexes, which define the risk calculation for different types of objects. Certain properties of default risk index functions can be edited in One Identity Manager. You can also can set up custom risk index functions.
For more information about risk assessment, see the One Identity Manager Risk Assessment Administration Guide.

Table 26: Risk index function main data
Description |
Enter a description of the risk index function. |
Calculate immediately |
Select the check box to ensure that the risk index is calculated immediately. If you clear the check box, calculation is triggered asynchronously via the DBQueue processor. |
Disabled |
Select this check box if you do not want the risk index function to be taken into account in the overall the calculation of the risk indexes (see Disabling/enabling risk index functions). |
Calculation type |
Select the calculation type to be used for calculating the risk index:
-
Maximum (weighted): The highest value from all relevant risk indexes is determined, weighted and used as the basis for further calculation.
-
Maximum (normalized): The highest value from all relevant risk indexes is calculated, weighted with the normalized weighting factor and taken as basis for the next calculation.
-
Increment: The risk index of table column (target) is incremented by a fixed value. This value is specified in Weighting/Change value.
-
Decrement: The risk index of the table column (target) is decreased by a fixed value. This value is specified in Weighting/Change value.
-
Average (weighted): The average of all relevant risk indexes is calculated, weighted, and taken as basis for the next calculation.
-
Average (normalized): The average of all relevant risk indexes is calculated with the normalized weighting factor and taken as basis for the next calculation.
-
Reduction: Used when calculating the reduced risk index for compliance rules, SAP functions, company policies, and attestation policies. You cannot add custom functions with this calculation type! |
Weighting/change value |
Use the slider to set the value either with which to weight the risk index in the overall calculation or the value by which the risk index will change. |

Click Save.
If risk index functions are not to be taken into account in the overall calculation of risk indexes, you can disable them. You can enable disabled risk index functions again.
