Accountability sits with the security and identity leadership team, because credential security is now a foundational control for business access across people and machines. Governance should define ownership for visibility, issuance, storage, rotation, and revocation, with clear reporting into security and risk programmes. Without explicit accountability, gaps persist between teams and tools.
Why This Matters for Security Teams
Organisation-wide credential security is not just a hygiene issue. It determines who, or what, can access sensitive systems, move through environments, and trigger business processes. That makes it a governance problem as much as a technical one. NIST’s control baseline in NIST SP 800-53 Rev 5 Security and Privacy Controls treats identity, access, and auditability as core safeguards, but many organisations still split responsibility across IAM, infrastructure, application, and platform teams.
For non-human identities, that split becomes dangerous because secrets are often created in code, copied into pipelines, reused across services, and forgotten long before they are rotated. NHIMG research on the Guide to the Secret Sprawl Challenge and the Ultimate Guide to NHIs — Static vs Dynamic Secrets shows how quickly unmanaged secrets spread once multiple teams can issue or store them. In practice, many security teams encounter credential exposure only after a service account or API key has already been abused.
How Accountability Should Work in Practice
The accountable function is typically security leadership, with identity leadership as the operational owner, because the control span covers both employee credentials and machine identities. The organisation needs one governance model for issuance, storage, rotation, revocation, and monitoring, even if different teams execute parts of it. That model should define who approves access, who manages the technical controls, and who receives risk reporting when exceptions are made.
Practically, this means:
- Setting one policy for human and non-human credential lifecycle management.
- Assigning clear ownership for secret vaults, federation, and key rotation.
- Using access reviews that include service accounts, API keys, and workload identities.
- Escalating unresolved exceptions into security risk reporting, not local team queues.
For machine identities, the scope must include dynamic credentials and workload authentication, not just stored passwords or keys. That is why guidance such as the OWASP Non-Human Identity Top 10 matters: it frames secret misuse, over-permissioning, and lifecycle drift as identity problems, not isolated engineering issues. NHIMG’s reporting on the 2024 Non-Human Identity Security Report also shows that 88.5% of organisations say their non-human IAM practices lag behind or merely match human IAM, which is a strong signal that ownership is still too diffuse.
Security and identity leaders should therefore own the control design, while platform and application teams own implementation within a common standard. These controls tend to break down when each engineering team is allowed to manage its own secrets and service accounts because no single owner can see cross-environment drift.
Common Variations and Edge Cases
Tighter credential governance often increases operational overhead, requiring organisations to balance faster delivery against stricter review, rotation, and exception handling. That tradeoff becomes most visible in hybrid estates, mergers, and shared platform environments where different teams inherited different tools and conventions.
There is no universal standard for this yet, but current guidance suggests a central accountability model with federated execution. In a small organisation, the CISO or head of security may own the function directly. In a larger enterprise, the identity engineering lead may operate the platform, while security retains policy authority and risk acceptance. Either way, accountability should never sit only with individual application teams.
Edge cases matter. Shared admin accounts, break-glass credentials, legacy service accounts, and third-party integrations often fall between team boundaries. These should be explicitly named in policy, assigned an owner, and reviewed on a fixed schedule. When organisations discover credential sprawl, the issue is usually not the absence of tools. It is that no one was formally accountable for the whole lifecycle across people and machines.
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, NIST SP 800-63 and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | PR.AA-01 | Accountability depends on clear identity governance and access ownership. |
| OWASP Non-Human Identity Top 10 | NHI-01 | Covers non-human identity governance, ownership, and lifecycle control. |
| NIST SP 800-63 | Identity assurance and authentication guidance supports accountable credential management. | |
| NIST AI RMF | GOVERN | Governance is needed to assign responsibility for identity security across systems. |
| CSA MAESTRO | ID-2 | Agent and workload identity management needs explicit ownership and control. |
Assign named owners for credential lifecycle controls and review them through your identity risk process.
