Accountability usually sits with identity, application, and platform owners together, because SAP access spans multiple control domains. Security leaders should expect shared responsibility for approvals, policy enforcement, and audit evidence. Governance teams need clear ownership for certifications, GRC alignment, and remediation so that access decisions are traceable across the full SAP landscape.
Why This Matters for Security Teams
When SAP access is governed inconsistently across cloud and on premises environments, accountability becomes blurred between identity teams, SAP application owners, infrastructure teams, and audit functions. That gap is risky because access in SAP often spans privileged roles, business-critical transactions, and non-human identities that are hard to see in standard reviews. Current guidance from the NIST Cybersecurity Framework 2.0 emphasizes clear governance and ownership for control outcomes, not just technical configuration.
NHIMG research on broader NHI governance shows why this matters operationally: the 2024 ESG Report: Managing Non-Human Identities found that 72% of organisations have experienced or suspect a breach of non-human identities. In SAP environments, that kind of exposure often hides in overlapping approval paths, inconsistent role design, and weak evidence collection across platforms. In practice, many security teams discover the ownership problem only after a failed audit or a privileged access incident has already exposed the inconsistency.
How It Works in Practice
Accountability should be assigned by control domain, then tied together through a single governance model. For SAP, that usually means identity owners define who can authenticate, application owners define what roles and transactions are allowed, and platform or basis teams enforce how those controls are implemented in each environment. Security leadership is responsible for ensuring the model is consistent across cloud and on premises systems, while GRC or compliance teams verify that approvals, recertifications, and evidence are complete.
This approach is aligned with the OWASP Non-Human Identity Top 10, which treats credential governance, over-privilege, and lifecycle control as first-order risks. For SAP specifically, practitioners should document:
- who approves access for human users versus service accounts and integrations
- which team owns role design, segregation of duties, and emergency access
- where policy is enforced for cloud identity providers and on premises directories
- how access reviews are evidenced across both landscapes
- who remediates exceptions when entitlement drift is detected
NHIMG’s Top 10 NHI Issues is useful here because the same operational pattern appears in SAP: when identities, secrets, and approvals are managed separately, no single owner sees the full risk. The practical answer is not to assign one team everything, but to assign one accountable owner for the end-to-end control outcome and require explicit handoffs between the teams that execute it. These controls tend to break down when SAP is split between SSO-driven cloud access and legacy on premises administration because evidence, approvals, and remediation live in different systems.
Common Variations and Edge Cases
Tighter cross-domain governance often increases coordination overhead, requiring organisations to balance faster access delivery against stronger accountability. That tradeoff is especially visible in hybrid SAP estates, where some access paths are managed through central identity governance while others are still handled locally by functional teams. Best practice is evolving, but there is no universal standard for this yet: the important point is that ownership must still be explicit even when implementation is distributed.
Edge cases include third-party support accounts, emergency firefighter access, and service integrations that bypass normal approval flows. In those cases, the accountable owner is still the business or platform function that accepted the risk, even if a separate team performed the technical change. Security teams should also be careful not to let certification ownership drift into a compliance-only exercise; if a role owner cannot explain the business purpose of access in both cloud and on premises SAP, the governance model is too weak. For audit-ready traceability, align the operating model with the NIST Cybersecurity Framework 2.0 and maintain supporting references in the Ultimate Guide to NHIs — Regulatory and Audit Perspectives. The model fails fastest when ownership is assumed rather than documented, because local exceptions then accumulate faster than governance can reconcile them.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 and CSA MAESTRO address the attack and risk surface, while NIST CSF 2.0 and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | SAP access often relies on secrets and service identities that need lifecycle control. |
| NIST CSF 2.0 | GV.OV-01 | This question is about governance accountability across shared SAP control domains. |
| NIST AI RMF | GOVERN | Shared accountability needs clear governance, oversight, and traceable decision-making. |
| CSA MAESTRO | GOV-02 | Agentic governance patterns apply to distributed control ownership and auditability. |
Assign one owner for each non-human SAP identity and review its lifecycle, scope, and rotation on a fixed cadence.
