An access review campaign is a scheduled process where application owners, managers, or delegates confirm whether existing permissions should remain in place. It is a control for removing excess access, but it only works when reviewers can understand the permissions and complete decisions reliably.
Expanded Definition
An access review campaign is a time-boxed governance exercise that asks accountable reviewers to confirm whether each entitlement still has a valid business need. In NHI environments, the campaign should cover service accounts, API keys, bot identities, workload roles, and delegated agent permissions, not just human users. Definitions vary across vendors, but the operational goal is consistent: reduce privilege creep by making an explicit keep or remove decision for every item under review.
That distinction matters because access reviews are not the same as provisioning, recertification in a general IAM program, or privileged elevation approvals. A campaign is a repeatable control with a defined start, scope, evidence set, and completion deadline. It becomes more reliable when entitlements are grouped by owner, application, environment, and risk tier, and when the reviewer can understand what the identity actually does. OWASP’s OWASP Non-Human Identity Top 10 highlights how weak NHI governance turns into exposure when secrets, tokens, and workload permissions drift beyond their intended use.
The most common misapplication is treating the campaign as a checkbox exercise, which occurs when reviewers approve items they do not understand because the entitlement data is incomplete or overly technical.
Examples and Use Cases
Implementing access review campaigns rigorously often introduces reviewer burden and decision friction, requiring organisations to weigh stronger privilege hygiene against slower approval cycles and more governance overhead.
- A platform team reviews all Kubernetes service accounts before a quarterly release window and removes bindings for jobs that no longer run, using lifecycle guidance from the NHI Lifecycle Management Guide.
- A finance application owner validates which automation identities still need payment-system access, then marks stale roles for removal after comparing activity logs with business ownership.
- A security team runs a campaign on cloud access keys after reading the Ultimate Guide to NHIs and classifies dormant credentials by workload criticality.
- An AI operations lead reviews agent permissions that allow file access, ticket creation, and tool execution, then narrows authority to the minimum set needed for current workflows, consistent with the OWASP Non-Human Identity Top 10.
- A cloud centre of excellence compares campaign results against breach patterns documented in the 52 NHI Breaches Analysis to identify recurring overprovisioning across projects.
These examples show that the campaign is most useful when ownership is clear, entitlement descriptions are readable, and reviewers can act on evidence rather than assumptions.
Why It Matters in NHI Security
Access review campaigns matter because NHIs accumulate privileges silently. An identity created for automation today may still be active months later, connected to production data, secret stores, or agent toolchains long after the original business need has changed. When campaigns are weak, organisations tend to preserve inherited access, which increases blast radius after a token leak, code compromise, or misconfigured workload role. That risk is not theoretical: Entro Security reports that when AWS credentials are exposed publicly, attackers attempt access within an average of 17 minutes, and as quickly as 9 minutes in some cases, underscoring how little time remains to clean up stale entitlements once exposure occurs.
NHIMG analysis also shows why access review quality matters across the broader secrets lifecycle, especially when review outcomes are disconnected from remediation. In Ultimate Guide to NHIs — Key Challenges and Risks, the operational theme is clear: unmanaged NHI access tends to become visible only after an incident, not during steady-state operations. Practitioners should treat campaign results as a trigger for remediation, not a record-keeping exercise. After that, the next step is usually to link the review outcome to secret rotation, role reduction, or identity retirement.
Organisations typically encounter the need for an access review campaign only after an audit finding, privilege misuse, or secret exposure, at which point the control 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-02 | Covers review and governance gaps that let NHI permissions persist unchecked. |
| NIST CSF 2.0 | PR.AC-4 | Least-privilege access governance depends on periodic entitlement validation. |
| NIST Zero Trust (SP 800-207) | N/A | Zero trust requires continuous verification of access legitimacy, including NHIs. |
Schedule recurring access recertification and revoke privileges that no longer match business need.
