Look for three signals: credentials are owned, rotated and reviewed on a schedule; access is tied to enterprise identity policy; and logs show retrieval and administrative changes to the secure user store. If any of those are missing, the control is only partially effective.
What “working” means for SAP HANA credential controls
Credential controls are only working if they prove three things at once: the secure store has accountable ownership, credentials move through a defined lifecycle, and privileged retrievals are limited to approved identity paths. For SAP HANA, that means teams should be able to show who can access the store, when secrets were last rotated, and whether administrative changes are auditable.
The practical test is not whether the store exists, but whether it changes behaviour. If access still depends on shared knowledge, stale secrets, or undocumented exceptions, the control may exist on paper while leaving the database exposed in practice.
That is why evidence matters as much as configuration. A control that cannot produce ownership records, rotation history, and access logs is difficult to trust during incident review, audit, or recovery.
How to test ownership, rotation, and enterprise identity binding
Start with ownership and lifecycle. Every SAP HANA credential in scope should have a clear custodian, a renewal or review date, and a defined reason for existence. The Guide to the Secret Sprawl Challenge is useful background when the issue is not a single secret but unmanaged growth across systems.
Then test whether the credential is really governed by enterprise identity policy. If access to the secure store bypasses central identity, or if changes can be made without approved administrative roles, the control is not anchored in the broader access model. That is where OWASP Non-Human Identity Top 10 provides a useful lens on lifecycle, privilege, and secret handling.
Rotation is the next proof point. A strong control should show that the secret changes on schedule, that dependent applications still function after change, and that old values are invalidated rather than left usable. The most common failure is treating rotation as a calendar task while ignoring dependency mapping and rollback behaviour.
What the logs should prove when the control is effective
Logging needs to show more than generic system activity. Teams should expect records for secret retrieval, administrative updates, policy changes, and any failed or unusual access attempt. If those events are not captured at a level that can be reviewed later, you cannot reliably tell whether the secure store is being used correctly or merely assumed to be.
The most valuable log question is simple: can you reconstruct who accessed the credential, when they did it, and what change followed? That evidence is what separates a control that is enforceable from one that is only documented. For broader logging and accountability expectations, NIST SP 800-53 Rev 5 Security and Privacy Controls remains a strong reference point for auditability and access control.
Administrative changes also matter because they often reveal drift before an incident does. If an operator can alter policy, export secrets, or widen access without a review trail, the secure user store becomes a high-value bypass point rather than a control.
Risk and Threat Considerations
When SAP HANA credential controls fail, the failure is usually silent until a breach, outage, or audit exposes it. The main risk is not just secret theft, but weak accountability, stale credentials, and excessive administrative reach that turn a protected store into an attractive target.
Failure mechanism: controls break when ownership is unclear, rotation is not enforced end to end, or logging does not capture retrieval and change events, leaving exploitable secrets and untraceable changes in place.
Impact: attackers or insiders can reuse long-lived credentials, expand access, or hide unauthorised changes, while defenders lose the evidence needed to prove containment, support forensics, or restore trust in the store.
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 addresses the attack and risk surface, while NIST SP 800-53 Rev 5 sets the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-53 Rev 5 | IA-5 — Authenticator Management | SAP HANA credential controls depend on rotation, revocation, and lifecycle handling. |
| AU-2 — Audit Events | Logging retrieval and administrative changes is central to proving the control works. | |
| AC-2 — Account Management | Ownership and approved access paths hinge on controlled account administration. | |
| Recommendation — Enforce credential lifecycle rules and verify rotation, revocation, and reuse limits. Log credential retrieval and administrative changes as auditable events. Restrict and review administrative access to the secure store. | ||
| OWASP Non-Human Identity Top 10 | NHI-01 — Improper Offboarding | Credential controls fail when ownership and lifecycle do not remove stale access. |
| NHI-07 — Long-Lived Secrets | The question checks whether secrets are rotated rather than left usable indefinitely. | |
| Recommendation — Remove obsolete access paths and retire secrets on schedule. Replace long-lived credentials with short-lived or rotated secrets. | ||
Practitioner Guidance
What to verify: confirm that each SAP HANA secret has an owner, a rotation interval, and a documented dependent system list. If any secret cannot be rotated without manual exception handling, treat that as a control weakness rather than a minor operational inconvenience.
What good looks like: retrievals are limited to named admin paths, rotation succeeds without breaking consumers, and logs can link every credential change to a legitimate change request or maintenance event. That is the minimum evidence that the control is actually governing access, not merely storing passwords.
Practitioner takeaway: a credential control is only real when you can prove lifecycle discipline, identity-bound access, and auditable use all at the same time.
