Ownership should be shared, but the response must be coordinated. Application owners need to fix the vulnerability, IAM and PAM teams need to remove excess privilege, and audit or GRC teams need to verify that sensitive business actions are being monitored and recertified.
Why This Matters for Security Teams
When ERP abuse crosses patching and access control, the problem is no longer just a software defect or a permissions issue. It is a compound identity failure that can let a small weakness become financial fraud, unauthorized posting, or silent data manipulation. That is why NHI Management Group treats this as a coordinated remediation problem, not a single-team ticket. Guidance from the OWASP Non-Human Identity Top 10 is especially relevant because ERP abuse often rides on service accounts, integrations, and stale secrets rather than on a user login.
The practical risk is that patching alone does not remove excess privilege, while IAM cleanup alone does not close the vulnerable code path. In parallel, ERP environments often contain long-lived automation accounts, direct database connections, and business-critical integrations that are difficult to interrupt without a clear owner. NHIMG research on the Ultimate Guide to NHIs shows that 97% of NHIs carry excessive privileges and 71% are not rotated within recommended time frames, which makes shared remediation discipline essential rather than optional. In practice, many security teams discover the abuse only after suspicious postings or extractive transactions have already occurred.
How It Works in Practice
Ownership should be divided by control surface, but coordinated through a single remediation lead. The application owner typically owns the ERP defect: the vulnerable module, business logic flaw, missing input validation, or patch deployment. IAM and PAM teams own the identity layer: removing overbroad roles, disabling dormant service accounts, rotating secrets, and converting static credentials to short-lived access where possible. Audit or GRC owns assurance: validating that high-risk actions are logged, recertified, and tied to an accountable business owner.
This model aligns with current security guidance because ERP abuse usually spans multiple trust boundaries. A patch may stop one exploit path, but if the same account still has posting, export, or admin rights, the attacker can keep operating through a different workflow. Similarly, access review without remediation of the vulnerable ERP component leaves the original entry point open. NHI Management Group’s Key Challenges and Risks section highlights how excessive privilege and poor visibility compound each other across service accounts and integrations.
- Application owners patch the ERP issue, test the fix, and confirm no business process regression.
- IAM and PAM teams revoke unnecessary rights, tighten role mappings, and rotate exposed secrets.
- GRC validates that the affected transactions are covered by monitoring, recertification, and evidence retention.
- Incident response tracks whether the same identity was used across multiple systems and adjusts containment accordingly.
For control mapping, the OWASP NHI guidance and the PCI DSS v4.0 document both reinforce that privilege reduction and traceable authorization matter as much as code fixes. These controls tend to break down when ERP access is owned informally by a business unit that can approve changes faster than central security can verify them.
Common Variations and Edge Cases
Tighter remediation control often increases downtime and coordination overhead, requiring organisations to balance fast containment against business continuity. That tradeoff becomes most visible in ERP systems that support payroll, finance close, procurement, or manufacturing execution, where a patch cannot simply be rushed through without testing and approval. Best practice is evolving, but there is no universal standard for this yet: some enterprises centralize all decisions in incident response, while others keep operational ownership with the ERP platform team and assign security veto authority only for high-risk changes.
A few edge cases matter. If the abused account is a shared integration identity, IAM and PAM must treat it as a high-priority non-human identity rather than as a normal application credential. If the issue involves a custom ERP extension, the application team may need to ship both a code fix and a permission redesign. If the abuse was enabled by excessive entitlements but no confirmed exploit path exists, GRC may prioritize recertification and compensating controls while the technical teams complete remediation. The key is to avoid single-threaded ownership that leaves one half of the problem unresolved.
NHIMG’s 52 NHI Breaches Analysis and the Guide to the Secret Sprawl Challenge both show why fragmented ownership creates repeat exposure: the exploit is patched, but the credential, privilege, or monitoring gap remains. That is why shared accountability with one coordinating owner is the safer operating model.
