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.
In the context of Identity Audit, compliance rules 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 or direct assignment), attestations, exception approvals for rule violations, identity's 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.
