Accountability should sit with the business owner of the delegated access, the identity team that approved the scope, and the platform team that allowed it to persist. Frameworks like NIST CSF and OWASP NHI both point toward clear ownership, review, and revocation as the controls that matter most.
Why This Matters for Security Teams
When a delegated app or secret is abused, the breach is rarely just a technical failure. It usually exposes a gap in ownership, approval, and review. The business owner benefits from the access, the identity team defines the scope, and the platform team keeps the entitlement alive. That shared chain is exactly why NHI governance has become a board-level concern, not just an IAM task.
In practice, the risk shows up fastest in secret sprawl, overbroad service accounts, and delegated integrations that survive well past the original use case. NHIMG research on the Secret Sprawl Challenge shows how quickly unmanaged credentials multiply across pipelines and tooling, while the OWASP Non-Human Identity Top 10 frames excessive standing privilege and weak lifecycle control as recurring root causes. The important point is accountability: a control owner is not the same as the business risk owner, and a ticket approval is not the same as ongoing governance.
One useful signal comes from The 2024 ESG Report: Managing Non-Human Identities by Oasis Security & ESG, which found that 72% of organisations have experienced or suspect a breach of non-human identities. In practice, many security teams encounter the accountability question only after a delegated secret has already been used to move laterally or exfiltrate data, rather than through intentional lifecycle review.
How It Works in Practice
Accountability for delegated access should be mapped across three layers: business ownership, technical control, and operational persistence. The business owner is accountable for why the access exists and whether it still supports a real workflow. The identity or security team is accountable for policy, scope, and review. The platform team is accountable for making revocation, rotation, and expiration actually work in production.
That model is consistent with current guidance from OWASP Non-Human Identity Top 10 and with NIST zero trust thinking, where access is continuously evaluated instead of assumed valid forever. For delegated apps, that usually means:
- Assign a named business owner for every app registration, service principal, or API integration.
- Track the approving identity team or platform control owner for scope, rotation, and exceptions.
- Use least privilege and explicit expiration dates for shared secrets, tokens, and certificates.
- Require periodic attestation that the delegated access is still needed.
- Revoke unused credentials automatically, not only during quarterly reviews.
For higher-risk workflows, the best practice is evolving toward just-in-time access, ephemeral credentials, and workload identity instead of static secret. NHI Management Group’s research on 52 NHI Breaches Analysis and 230M AWS environment compromise shows the same pattern: once a credential outlives its intended scope, accountability becomes forensic instead of preventive. These controls tend to break down when app ownership is unclear in CI/CD-heavy environments because credentials are created faster than they are reviewed.
Common Variations and Edge Cases
Tighter delegated-access governance often increases operational overhead, so organisations have to balance speed against revocation discipline. That tradeoff is especially visible in dev teams, SaaS integrations, and machine-to-machine automations where a single secret may support many services.
There is no universal standard for this yet, but current guidance suggests treating the following cases differently:
- Shared secrets: accountability must include the platform owner because revocation and blast radius are platform problems.
- Vendor-managed integrations: the business owner still carries risk, even if the vendor operates the mechanism.
- Emergency access: accountability shifts to the approver and the incident commander, with strict time bounds.
- Agentic workloads: the agent or delegated app may act autonomously, but the human or team that authorised the tool access still owns the outcome.
In agentic or highly automated environments, static role assignment is often too slow to reflect real behaviour. That is why frameworks such as Anthropic’s report on AI-orchestrated cyber espionage matter operationally: autonomous systems can chain tools and secrets in ways humans do not predict. Shai Hulud npm malware campaign illustrates the same lesson in supply chain form. The practical takeaway is simple: if no one can answer who approved the access, who owns the app, and who can revoke it today, the organisation does not actually control it.
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 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 | Directs clear ownership and lifecycle control for non-human identities. |
| NIST CSF 2.0 | PR.AC-1 | Access provisioning and authorization are central to delegated-access accountability. |
| NIST AI RMF | GOVERN | Accountability for autonomous or delegated systems starts with governance and ownership. |
Assign owners to every delegated app and secret, then review and revoke access on a fixed cadence.
