Determining the responsible approvers

The DBQueue Processor calculates which employee is authorized as an approver and in which approval level. Once a request is triggered, the approvers are determined for every approval step of the approval workflow to be processed. Changes to responsibilities may lead to an employee no longer being authorized as an approver for a request that is not yet finally approved. In this case, approvers must be recalculated. The following changes can trigger a recalculation for as yet unapproved requests:

  • Approval policy, workflow, step, or procedure changes.

  • An authorized approver loses their responsibility in One Identity Manager, for example, if a change is made to the department manager, product owner, or target system manager.

  • An employee obtains responsibilities in One Identity Manager and therefore is authorized as an approver, for example as the manager of the request recipient.

  • An employee authorized as an approver is deactivated.

Once an employee's responsibilities have changed in One Identity Manager, an approver recalculation task is queued in the DBQueue. By default, all approval steps of the pending approval processes are recalculated at the same time. Approval steps that have already been approved remain approved, even if their approver has changed. Recalculating approvers may take a long time depending on the configuration of the system environment and the amount of data to be processed. To optimize this processing time, you can specify the approval steps for which the approvers are to be recalculated.

To configure recalculation of approvers

  • In the Designer, set the QER | ITShop | ReducedApproverCalculation configuration parameter and select one of the following options as the value.

    Table 44: Options for recalculating approvers
    Option Description

    No

    All approval steps are recalculated. This behavior also applies if the configuration parameter is not set.

    Advantage: All valid approvers are displayed in the approval process. The rest of the approval sequence is transparent.

    Disadvantage: Recalculating approvers may take a long time.

    CurrentLevel

    Only approvers for the approval level that is currently to be edited are recalculated. Once an approval level has been approved, the approvers are determined for the next approval level.

    Advantage: The number of approval levels to calculate is lower. Calculating the approvers may be faster.

    TIP: Use this option if performance problems occur in your environment in connection with the recalculation of approvers.

    Disadvantage: The originally calculated approvers are still displayed in the approval sequence for each subsequent approval step, even though they may no longer have approval authorization. The rest of the approval sequence is not correctly represented.

    NoRecalc

    No recalculation of approvers The previous approvers remain authorized to approve the current approval levels. Once an approval level has been approved, the approvers are determined for the next approval level.

    Advantage: The number of approval levels to calculate is lower. Calculating the approvers may be faster.

    TIP: Use this option if performance problems occur in your environment in connection with the recalculation of approvers, even though the CurrentLevel option is used.

    Disadvantage: The originally calculated approvers are still displayed in the approval sequence for each subsequent approval step, even though they may no longer have approval authorization. The rest of the approval sequence is not correctly represented. Employees that are no longer authorized can approve the current approval level.

    In the worst-case scenario, the only attestors originally calculated here now have no access to One Identity Manager, for example, because they have left the company. The approval level cannot be approved.

    To see approval steps of this type through

    • Define a timeout and timeout behavior when you set up the approval workflows on the approval steps.

      - OR -

    • When setting up the IT Shop, assign members to the chief approval team. These can access open approval processes at any time.

Request risk analysis

Everyone with IT system authorization in a company represents a security risk for that company. For example, a person with permission to edit financial data in SAP carries a higher risk than an employee with permission to edit their own personal 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 person who is assigned this company resource, 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.

Every time a company resource with a specified risk index is assigned, the employee's risk index may exceed a permitted level. You can check the risk index of company resources if they are requested through the IT Shop. If the risk index is higher than the specified value, the request is denied.

To set up risk assessment for requests

  • Create an approval workflow.

    1. Add an approval step with the RI approval procedure.

    2. In the Condition field, enter the comparison value for the risk index. Enter a number in the range 0.0 to 1.0.

    3. Enter other approval levels if required.

The approval step is granted approval by One Identity Manager if the risk index of the requested company resource is lower than the comparison value. If the risk index is higher or equal to the comparison value, the approval step is not granted approval.

Risk assessment of requests works for both direct company resource request and assignment requests. Only risk indexes with inputted values are examined for the approval decision; calculated risk indexes are not taken into account. Therefore, risk assessment of requests only works if the product's original table or one of the member tables of a requested assignment has a RiskIndex column. If the table only has the RiskIndexCalculated column, the request is automatically approved. If both member tables of an assignment request have a RiskIndex column, the highest of the two risk indexes is used as the basis for the approval.

If the company resource request or an assignment has been granted approval, the employee's risk index is recalculated the next time the scheduled calculation task is run.

Testing requests for rule compliance

Installed modules: Compliance Rules Module

You can integrate rule conformity testing for IT Shop requests within an approval workflow. A separate approval procedure is supplied for this. This approval procedure checks whether the request's recipient will violate compliance rules if the requests are granted approval. The result of the test is logged in the request's approval sequence and approval history.

Table 45: Approval procedures for compliance checking

Approval procedure

Description

CR - compliance check (simplified)

Checks the current request for possible rule violations. It takes into account the requested product and all the company resources already assigned to the request recipient.

Prerequisites for request validation

Compliance checking requests

To retain an overview of potential rule violations, you can run a simplified compliance check. Use the CR approval procedure to test requests for possible rule violations before finally approving them.

The following data of a recipient's request is taken into account by the compliance check:

  • All pending requests

  • All company resources already assigned to the recipient

  • All the recipient's user accounts

  • All entitlement in the target system (for example, Active Directory groups or SAP roles) the recipient has obtained through these user accounts

Auxiliary tables for object assignments are regularly evaluated for the compliance check. Auxiliary tables are calculated on a scheduled basis. Furthermore, the approval procedure only takes into account compliance rules that are created using the simplified definition.

Rule checking does not completely check the requests with this. It is possible that under the following conditions, rule checking does not identify a rule violation:

  • Customer permissions change after the auxiliary table have been calculated.

  • If memberships are requested in business role or organization, a rule is violated by an object that is inherited through the business role or organization. Inheritance is calculated after request approval and can therefore not be identified until after the auxiliary table is calculated again.

  • The customer does not belong to the rule's employee group affected until the request is made.

  • The rule condition was created in expert node or as a SQL query.

TIP: A complete check of assignments is achieved with cyclical testing of compliance rule using schedules. This finds all the rule violations that result from the request.

It is possible that under the following conditions, rule checking identifies a rule violation where one does not exist:

  • Two products violate one rule when they are assigned at the same time. The product requests are, however, for a limited period. The validity periods does not overlap. Still a potential rule violation is identified.

TIP: These requests can be approved after checking by exception approver as permitted by the definition of the violation rule.

The compliance check is not only useful for specifying which rule is violated by a request, but it can also find out which product in the request caused the rule violation. This makes a detailed analysis possible of the rule violation. The request can still be approved by exception approval, the definition of compliance rules permitting. Additional approval steps are added in approval workflows to deal with exception approval.

Conditions for compliance checking requests

  • You can add only one approval step per approval policy with the CR approval procedure.

  • The rule conditions were created in the simple definition.

  • IT Shop properties that are specified for each rule are taken into account in the rule testing. Identification of a rule violation depends on the setting on Rule violation identified.

  • The compliance check should be added as the last approval level in the approval workflow. The subsequent approval levels only get one approval step to determine the exception approver if approval is denied.

Compliance check sequence

  1. If an approval step for compliance checking using the CR approval procedure is found in the request’s approval procedure, all products in pending requests are assigned to the customer. It is assumed that all pending requests will be approved and therefore the customer will obtain all the products. The current request is then analyzed with respect to potential violations against the defined rules.

  2. If no rule violations are found, the approval step is automatically granted approval and the request is passed on to the approver at the next approval level above.

  3. If a rule violation is detected, the request is automatically not granted approval. The request can still be approved by exception approval, the definition of rule violations permitting.
