How does SAP IAG differ from SAP GRC Access Control?

SAP IAG Features

In this Article we will discuss an in-depth exploration of the Access Analysis Service, a component within SAP Cloud Identity Access Governance (IAG) that closely mirrors the functionality of Access Risk Analysis in SAP GRC AC (Access Control). This service facilitates the effective management of risks within systems connected to IAG. We underscored key distinctions from GRC AC (Access Control), notably the native risk analysis capability for Cloud systems. Unlike GRC AC (Access Control), which limits this feature to SuccessFactors, IAG allows native risk analysis for a broader spectrum of Cloud applications. Additionally, IAG enables cross-system risk analysis, encompassing both Cloud and non-Cloud applications.

Emphasis was placed on the benefits of Privilege Access Management (PAM), a tool that empowers the management of emergency access from request initiation to review. Here we can also highlighted the integration of PAM with the Access Request Service, enabling the request for emergency access through an approval workflow. Notably, this tool can be utilized directly by end-users without administrative intervention when configured appropriately. Distinctive features of PAM in comparison to GRC AC (Access Control) were outlined, including its exclusive use in ABAP systems, dependence on ID-based emergency access, and decentralized usage. Moreover, PAM does not necessitate software installation on satellite systems, with ABAP being sufficient.

we proceeded to analyze the functionalities of the Access Request Service, a tool centralizing access management in SAP. It employs an approval workflow to enhance efficiency and traceability of changes. While there are differences in configurability compared to GRC AC, such as less customizable workflows, this service distinguishes itself by its ability to connect with both On-Premise and Cloud systems. Additionally, the integration of HR events for automating the Hire to Retire process sets it apart, even though customization in this aspect is not as extensive as in GRC AC.

Lastly, We delved into the Role Design Service within IAG functionalities, which oversees the lifecycle of SAP system roles. This service serves as a repository for roles that can be seamlessly added to access requests through the Access Request service.

Distinguishing itself from GRC AC, the Role Design Service in SAP Cloud Identity Access Governance (IAG) operates as a versatile repository accommodating both On-Premise and Cloud system roles. This service not only serves as a repository but also offers assistants to aid administrators in the creation of Business Roles. Moreover, it stands out by necessitating less information for the categorization of roles.

Integrations

Choosing Between GRC AC and IAG Implementation

Exclusive IAG Implementation: In this scenario, organizations opt for IAG as the singular access control application.

Hybrid Implementation (GRC AC + IAG):

In this configuration, SAP GRC AC manages access, while IAG, seamlessly integrated with SAP GRC AC, takes charge of tasks associated with Cloud systems. This encompasses functions such as risk analysis, emergency access, access requests, and role management.

Conclusions As demonstrated throughout this article, the optimal approach involves adopting a hybrid scenario where SAP GRC AC and SAP IAG collaborate. The decision between a purely Cloud model (IAG only), a blended model (IAG & GRC AC), or a purely On-Premise model (GRC AC) can be summarized as follows:

Cloud Solution:

Suited for organizations with fewer than 500 users or those with straight forward and standardized access control processes, particularly related to account management.

This option seamlessly adapts to default processes provided by SAP IAG and is ideal for scenarios requiring access control over Cloud-type systems. Notably, the licensing cost of SAP IAG is lower than that of SAP GRC AC.

Hybrid Solution:

Recommended for organizations with more than 500 users or those with complex processes. This solution is advantageous when an organization needs to manage access to Cloud systems and demands a high degree of customization in the tool. GRC AC offers enhanced adaptability, and when integrated with SAP IAG, it extends its capabilities to Cloud systems.
