Who is accountable when identity security gaps persist across applications and regulations?

Why This Matters for Security Teams

When identity security gaps persist across applications and regulations, the failure is rarely technical alone. It is usually an ownership problem: one team manages directories, another owns the application, and a third is asked to prove compliance after the fact. NIST’s Cybersecurity Framework 2.0 treats governance as a first-class security function for good reason. Without clear accountability, controls drift, exceptions multiply, and evidence becomes inconsistent.

This is especially visible in NHI programmes, where service accounts, API keys, and tokens often span cloud, CI/CD, SaaS, and legacy systems. NHIMG research shows only 5.7% of organisations have full visibility into their service accounts, and 68% do not know how to fully address NHI risks in practice. That gap matters because regulators do not accept “shared ownership” as a remediation plan. The organisation that owns the risk must also own the fix, even when execution is distributed across several teams.

In practice, many security teams discover accountability gaps only after audit findings, incident response, or a failed application upgrade expose them.

How It Works in Practice

Accountability has to be assigned at three levels: discovery, remediation, and evidence. Discovery means identifying which applications use which identities, secrets, and privileged paths. Remediation means deciding who rotates credentials, removes excessive privilege, updates code, or retires obsolete service accounts. Evidence means defining who can prove the control worked, when it worked, and against which assets. This structure aligns well with NIST SP 800-53 Rev. 5 Security and Privacy Controls, where control ownership and accountability are expected to be explicit rather than implied.

For NHI-heavy environments, best practice is to map each identity to a business service owner and a technical custodian. The business owner accepts risk, while the custodian executes rotation, revocation, monitoring, and exception handling. That model is stronger than a pure central IAM model because many gaps sit inside application code, scripts, build pipelines, or third-party integrations. NHIMG’s Ultimate Guide to NHIs notes that 96% of organisations store secrets outside secrets managers in vulnerable locations, which means ownership must extend into engineering workflows, not stop at the IAM team.

• Assign one accountable owner per application or service, not per tool.
• Separate control ownership from operational execution.
• Track every exception with expiry dates and named approvers.
• Require evidence for rotation, revocation, and access reviews, not just policy statements.

Where regulations differ, the accountable owner should still be the same internal function, even if the reporting format changes. That keeps remediation from fragmenting across audit, legal, security, and engineering. These controls tend to break down in federated SaaS and third-party OAuth environments because no single team can see the full identity chain end to end.

Common Variations and Edge Cases

Tighter accountability often increases coordination overhead, requiring organisations to balance speed against traceability. That tradeoff is real in merger environments, shared platforms, and outsourced development, where multiple teams believe they own the same identity surface. Current guidance suggests the answer is not more committees, but clearer decision rights and a documented escalation path. The accountable party should always be able to answer three questions: what identities exist, who can change them, and how compliance evidence is produced.

One common edge case is third-party access. If a vendor creates or uses NHIs inside your environment, the vendor may operate the tooling, but the organisation still owns the risk acceptance and regulatory exposure. Another edge case is legacy systems that cannot support modern lifecycle controls. In those cases, the accountable owner must document compensating controls and a retirement plan, not rely on informal monitoring. NHIMG’s 52 NHI Breaches Analysis and Top 10 NHI Issues show the same pattern repeatedly: fragmented ownership lets high-risk identities linger long after the original business need has passed.

There is no universal standard for exact organisational structure yet, but mature programmes treat accountability as a control requirement, not a reporting preference.
