They confuse completion with control. A spreadsheet-based access review can produce a record, but it does not guarantee that entitlements were accurate, owners were reachable, or removals were enforced. Without reliable data and follow-through, the review becomes documentation rather than governance.
Why This Matters for Security Teams
Manual access reviews for disconnected applications are often treated as a control because they produce a sign-off, but disconnected systems make verification far weaker than the paper trail suggests. The risk is not just stale access. It is broken ownership, incomplete inventories, and removals that never reach the target system. NHI Mgmt Group notes that only 5.7% of organisations have full visibility into their service accounts in the Ultimate Guide to NHIs, which is a useful warning for any review process that depends on accurate source data.
Disconnected applications amplify that problem because there is no clean integration path for entitlement snapshots, approval workflows, or automated deprovisioning. Teams often assume a reviewer can compensate for missing system signals, but reviewers usually do not know whether an entitlement is active, duplicated, or tied to a legacy account. The result is a governance activity that documents intent rather than enforcing it, which is especially dangerous when access is high privilege or shared across functions. In practice, many security teams discover review gaps only after an audit finding, an internal misuse event, or an unsuccessful offboarding attempt, rather than through intentional control validation.
How It Works in Practice
Effective reviews for disconnected applications start with scoping, not signatures. Teams need a reliable entitlement inventory, an assigned system owner, and a defined remediation path for every access decision. Without those three elements, the review cannot distinguish current access from inherited access or abandoned accounts. Current guidance suggests mapping disconnected applications to a minimum evidence set: user or service account, entitlement name, business justification, last-known activity, approver, and removal method. That gives reviewers enough context to judge whether access is still required.
In mature programs, the review is paired with compensating controls rather than treated as a standalone event. For example, privileged access may be constrained through OWASP Non-Human Identity Top 10 principles such as rotation, least privilege, and lifecycle discipline, while evidence is centralised in the NHI Lifecycle Management Guide. That matters because disconnected apps rarely support real-time removal, so the control has to prove that removals were queued, tracked, and confirmed by the system owner.
- Use a current entitlement export, not an old spreadsheet copy, as the review baseline.
- Require owners to attest to business need and last use, not just presence in the system.
- Track exceptions separately so orphaned accounts do not disappear into the approved population.
- Reconcile post-review removals against ticket closure or system logs where available.
Where possible, use independent checks such as password vault records, directory logs, or access provisioning tickets to validate that access was actually removed. These controls tend to break down when disconnected applications are old, ownerless, or shared across multiple business units because there is no authoritative record to reconcile against.
Common Variations and Edge Cases
Tighter review discipline often increases operational overhead, requiring organisations to balance audit confidence against manual effort. That tradeoff becomes sharper when the application is disconnected by design, such as a legacy mainframe, a vendor-hosted portal with limited APIs, or a plant-floor system that cannot accept frequent change. Best practice is evolving here: there is no universal standard for fully automating disconnected reviews, so teams should be explicit about compensating controls and residual risk.
One common edge case is shared or functional accounts. A reviewer may approve the account because the business function is real, while missing that the same credential is used by multiple people or processes. Another is dormant but still valid access, where no recent login does not prove the account is safe to keep. A third is emergency access, which often has a legitimate use case but is poorly documented after the event. In these scenarios, the review should require stronger evidence, including an owner who can explain why the entitlement still exists and a removal path that does not depend on the same person who approved it.
For teams trying to improve mature governance, the practical goal is not perfect automation. It is reducing the number of decisions made from stale data and ensuring the ones that remain have a verifiable follow-through. When that is not possible, the review should be marked as partially evidenced rather than treated as complete.
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 CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-05 | Disconnected app reviews fail when entitlements and lifecycle controls are not enforced. |
| NIST CSF 2.0 | PR.AA-01 | Access review quality depends on knowing who or what has access to each disconnected system. |
| NIST CSF 2.0 | PR.AC-4 | Least-privilege review is central when manual attestation replaces automation. |
Validate necessity for each entitlement and remove access that lacks current business justification.
