An access review process that records certification outcomes but cannot enforce them in the target application. It creates the appearance of governance while leaving entitlement changes dependent on manual follow-up, which weakens auditability and allows risk to persist after the review closes.
Expanded Definition
Read-only Review is a governance pattern in which reviewers can certify, reject, or comment on access decisions, but the outcome does not directly change entitlements in the target application. It is often used when the review system sits outside the identity plane, or when business owners want oversight without delegating enforcement. In NHI programs, that gap matters because service accounts, API keys, and workload identities often remain active long after a review closes.
Definitions vary across vendors, but the core distinction is simple: a true review drives remediation, while a read-only review only records intent. That means audit evidence may look complete even though the actual access state has not changed. This is especially risky for NHI estates with high credential churn, rotating secrets, or distributed ownership. The NIST Cybersecurity Framework 2.0 emphasizes governance outcomes that reduce risk, not just document it. Read-only Review should therefore be treated as a control signal, not a control outcome.
The most common misapplication is treating a signed certification report as proof of enforcement, which occurs when entitlement removals still depend on manual tickets or email follow-up.
Examples and Use Cases
Implementing Read-only Review rigorously often introduces workflow friction, requiring organisations to weigh faster attestation cycles against the cost of a separate remediation process.
- A platform team reviews cloud service accounts in a portal, but account disablement still requires a ticket to another operations queue.
- A security committee signs off on API key access, yet the review tool only exports a CSV and cannot revoke keys in the source system.
- An audit team uses a read-only dashboard to evidence quarterly certification for privileged workloads, while the engineering owner manually updates group membership afterward.
- An organisation maps review results into exception tracking, but closed exceptions do not automatically trigger secret rotation or JIT replacement.
- A mature NHI program compares review findings with inventory data from the Ultimate Guide to NHIs and then validates whether the target system actually accepted the change.
In standards-based identity operations, this pattern often appears where a review platform is separate from the enforcement point described in the NIST Cybersecurity Framework 2.0. The review remains useful for accountability, but it is not the same as automated entitlement reduction.
Why It Matters in NHI Security
Read-only Review becomes a security problem when teams mistake documentation for control. NHI risk does not decline if service accounts, secrets, and workload permissions remain active after certification. NHIMG research shows that only 20% of organisations have formal offboarding and key revocation processes, and 97% of NHIs carry excessive privileges, which makes unenforced review outcomes especially dangerous. The Ultimate Guide to NHIs also reports that 91.6% of secrets remain valid five days after an organisation is notified, underscoring how slow remediation can outlast the review itself.
That gap weakens auditability, creates false assurance for leadership, and allows dormant access to survive until it is exploited. It also complicates Zero Trust efforts, because policies that look governed on paper may still permit standing access in practice. Organisations typically encounter the consequences only after a breach review, access recertification failure, or failed offboarding event, at which point Read-only Review becomes operationally unavoidable to address.
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 Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-06 | Read-only reviews fail if certification does not drive entitlement removal. |
| NIST CSF 2.0 | PR.AA-04 | Access permissions must be reviewed and adjusted, not merely recorded. |
| NIST Zero Trust (SP 800-207) | AC-6 | Zero Trust requires least privilege to be enforced continuously, not noted after the fact. |
Ensure review results trigger actual NHI deprovisioning or secret revocation, not just documentation.
