Ownership should sit with both security operations and identity governance, with clear hand-offs for investigation, review, and remediation. Logs are not just an IT operations asset because they feed controls across authentication, privileged access, and third-party oversight. Shared ownership prevents evidence from sitting outside governance workflows.
Why This Matters for Security Teams
access log review is not a housekeeping task. It is one of the few controls that can show whether identity policy is actually working across authentication, privilege elevation, and third-party access. When ownership is vague, suspicious activity can sit in tooling without becoming an investigation, and remediation can stall between security operations, identity governance, and platform teams.
That matters even more for non-human identities, where service accounts and API keys are often over-privileged and under-observed. NHI Management Group notes that 97% of NHIs carry excessive privileges in its Ultimate Guide to NHIs, which means log review is often the only practical way to detect misuse before it becomes lateral movement. The control focus also aligns with the OWASP Non-Human Identity Top 10, which treats visibility and monitoring as core security gaps rather than optional operations hygiene.
In practice, many security teams discover logging gaps only after an access incident has already been reconstructed from incomplete evidence, rather than through intentional review discipline.
How It Works in Practice
Best practice is to split ownership by control stage, not by tool. Security operations should own the detection side: collecting logs, tuning alerts, triaging anomalies, and opening investigations. Identity governance should own the control side: validating whether access was legitimate, confirming whether policy was followed, and driving remediation such as revocation, step-up controls, or entitlement reduction. That split prevents logs from becoming an IT-only archive with no governance outcome.
For NHI-heavy environments, this should extend to workload identities, secret usage, and privileged session activity. Current guidance suggests treating log review as evidence for both Ultimate Guide to NHIs — Key Challenges and Risks and the OWASP Non-Human Identity Top 10, especially where service accounts are shared, secrets are long-lived, or third parties have indirect access. A useful operating model includes:
- Security operations triages alerts and enriches events with asset, user, and workload context.
- Identity governance validates whether the access path matched approved policy and business need.
- Privileged access teams confirm whether elevated sessions, vault use, or JIT grants were expected.
- Application or platform owners remediate root causes such as weak service-account scoping or missing telemetry.
Logs should also feed periodic access recertification, not just incident response. That is how teams identify dormant entitlements, anomalous API activity, and stale third-party access before they become recurring exceptions. These controls tend to break down when logs are fragmented across SaaS, cloud, and CI/CD platforms because no single owner can trace the full access path.
Common Variations and Edge Cases
Tighter log ownership often increases coordination overhead, requiring organisations to balance faster triage against stronger governance. That tradeoff is real in global environments, where security operations may be centralised but identity decisions are local, and in regulated sectors where auditors want a named control owner for every review action.
There is no universal standard for this yet, but current guidance suggests three common patterns. First, a SOC-led model works when the primary goal is threat detection, provided identity governance receives mandatory escalation on confirmed anomalies. Second, an IGA-led model works when the main risk is entitlement drift, but only if operations still monitors for suspicious behaviour. Third, a shared-service model works best for mature programmes with clear SLAs, evidence retention, and documented hand-offs.
Edge cases matter. Log review for privileged human admins may sit with PAM operations, while log review for machine identities may need workload teams because the signal lives in CI/CD, cloud control planes, or API gateways. The key is not who clicks “review,” but who is accountable for decision, evidence, and remediation. This is especially important when organisations are trying to close gaps highlighted in the Top 10 NHI Issues and when third-party access is involved, where review failures often show up only after trust has already been abused.
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 and CSA MAESTRO address the attack and risk surface, while 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-08 | Log review supports detection of anomalous NHI use and privilege abuse. |
| NIST CSF 2.0 | DE.CM-1 | Continuous monitoring requires defined ownership for access log review. |
| CSA MAESTRO | Agentic and cloud identity oversight depends on traceable review ownership. |
Set explicit operational and governance roles for reviewing identity events across cloud and workload systems.
