Who is accountable when a broken SAP administrative check exposes privileged functions?

Why This Matters for Security Teams

A broken SAP administrative check is not just an application defect. It is an access-control failure that can expose privileged functions to a service account, integration user, or administrative workflow that was never meant to hold that reach. That is why accountability sits with both SAP platform owners and identity governance owners: one side controls the authorization design, the other controls the identity lifecycle and review discipline. The risk is amplified when privileged paths are treated as “internal” and therefore trusted by default.

This is exactly the kind of issue that frameworks expect teams to prevent through least privilege, monitoring, and recertification. The NIST Cybersecurity Framework 2.0 and the OWASP Non-Human Identity Top 10 both point to the same operational reality: if machine identities can invoke privileged SAP functions without tight controls, the control gap is shared, not isolated. NHI Mgmt Group’s Ultimate Guide to NHIs — Why NHI Security Matters Now notes that 97% of NHIs carry excessive privileges, which is why SAP admin paths should be assumed sensitive until proven otherwise.

In practice, many security teams discover this only after a service principal has already exercised privileged access through a permissive check, rather than through intentional control testing.

How It Works in Practice

Accountability should be divided by control plane, not by incident blame. SAP platform owners are responsible for the application authorization model: which functions are protected, what checks gate them, and whether privileged transactions are exposed through custom code, RFC destinations, background jobs, or technical users. Identity governance owners are responsible for who or what can hold those identities, how access is approved, how often it is reviewed, and whether the identity is still justified.

In practice, teams should map each privileged SAP function to a named business owner, a technical owner, and an identity owner. Then they should verify three things:

• Privileged functions are protected by explicit authorization objects, not assumed application trust.
• Service principals and administrative users have narrowly scoped entitlements with documented purpose.
• Access reviews include non-human identities, not only named humans.

That operating model aligns with current guidance in the Ultimate Guide to NHIs — Key Challenges and Risks and with the NIST Cybersecurity Framework 2.0, which treats identity governance and access enforcement as shared responsibilities. Where SAP supports it, teams should also log privileged function use, recertify it on a fixed cadence, and remove standing access that is only needed for exceptional operations. The practical question is not whether the check exists, but whether it is enforced consistently across custom code, batch execution, and integration accounts. These controls tend to break down when legacy SAP roles, shared technical accounts, and custom authorization logic converge in one environment because ownership becomes fragmented across multiple teams.

Common Variations and Edge Cases

Tighter SAP authorization and identity review often increases operational overhead, requiring organisations to balance privileged access control against system uptime and change velocity. That tradeoff is real, especially where operations teams depend on shared technical users or emergency access. Best practice is evolving, but current guidance suggests that exceptions should be temporary, logged, and recertified rather than informal.

The hardest cases are not standard users. They are background jobs, middleware accounts, break-glass roles, and cross-system service principals that can reach SAP through RFC, API, or scheduler integration. In those environments, identity governance owners may approve the account, but platform owners still own the runtime authorization boundary. If either side assumes the other is monitoring the control, the gap remains open.

This is also where NHI-specific evidence matters. NHI Mgmt Group’s 52 NHI Breaches Analysis shows how machine identities are frequently involved in privilege exposure, and that pattern is consistent with SAP administrative checks that fail silently until an audit or incident exposes them. A useful rule is simple: if the function can change configuration, approve access, or expand privilege, then both the SAP control owner and the identity owner should be named in the accountability model. There is no universal standard for this yet, but the direction across OWASP and NIST is clear.
