Identity Manager 8.2 - Risk Assessment Administration Guide

Risk assessment

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.

Rules in the context of Identity Audit can also be given a risk index. Each rule violation can increase the security risk. Therefore, these risk indexes are also included in the employee’s risk calculation. You can define appropriate countermeasures through mitigating controls, and store them with the compliance rules.

Other factors can influence the calculation of employee risk indexes. These include: the type of resource assignment (approved request in the IT Shop or direct assignment), attestations, exception approvals for rule violations, employee 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.

One Identity Manager provides default functions for the risk index calculations described in the following. These are available if the respective module is installed. You can also can set up custom functions.

To use risk assessment functionality

  • In the Designer, set the QER | CalculateRiskIndex configuration parameter and compile the database.

If you disable the configuration parameter at a later date, model components and scripts that are not longer required, are disabled. SQL procedures and triggers are still carried out. For more information about the behavior of preprocessor relevant configuration parameters and conditional compiling, see the One Identity Manager Configuration Guide.

One Identity Manager users for configuring risk assessment

The following users are used for specifying risk indexes and editing risk index functions.

  • Create system users and permissions groups for non role-based login to administration tools in the Designer as required.

  • Enable or disable additional configuration parameters in the Designer as required.

  • Create custom processes in the Designer as required.

  • Create and configure schedules as required.

 

Defining risk index functions

A risk index can be entered in One Identity Manager for the following objects types.

NOTE: Object types are defined in the One Identity Manager modules and are not available until the modules are installed.
Table 2: Risk index for objects in the One Identity Manager
Object type Application Available in module

Target system entitlements, such as Active Directory groups or Google Workspace products and SKUs

Risk to the organization if the target system entitlement is assigned to a user account.

In the respective target system module

Software

Risk for the company if the account definition, software, or resource is assigned to an employee.

Software Management Module

Resources

always

Account definitions Target System Base Module
Multi-request resources Risk for the company if the resource is assigned to an IT Shop structure. always
Multi requestable/unsubscribable resources always
Assignment resources always

Risk for the company if SAP user accounts match the SAP function.

SAP R/3 Compliance Add-on Module

Company policies

Risk for the company if a company policy is violated.

Company Policies Module

Attestation policies

Risk for the company if an attestation procedure denies approval for an attestation policy.

Attestation Module

Subscribable reports

Risk for the company if an employee has subscribed to a report.

Report Subscription Module

To enter a risk index

  1. Open the main data form for the object for which you want to enter the risk index.
  2. Enter the desired value in the Risk index field.

    The risk index is specified as a floating point number in the range 0.0 ... 1.0. This means:

    • 0.0: no risk
    • 1.0: problem; risk involved

Calculating risk index functions

One Identity Manager calculates the resulting risk indexes for employees, user accounts, and hierarchical roles based on the risk indexes already stored. All direct and indirectly assigned objects are taken into account.

The risk index is calculated for the following object types.

Table 3: Object types with a calculated risk index

Object type

Calculation

Available in Module

Employees

Calculated from the risk indexes of all associated user accounts, directly, and indirectly assigned software applications, resources, account definitions, and subscribable reports, membership in application roles, and rule violations.

User accounts, such as Active Directory user accounts or Google Workspace user accounts

Calculated from the risk indexes of all assigned target system entitlements.

In the respective target system module
