Access Keys Older Than 90 Days
This page targets the check iam.access_keys_older_than_90_days and the query
"aws access key rotation 90 days" so teams can move from search to remediation quickly. Instead of broad
guidance, this page focuses on what the finding means in real operations, why it changes risk posture, and
the fastest path to a verified fix.
Posturio is built for practical cloud security operations. You can run a scan, confirm whether this issue exists in your environment, and prioritize remediation with clear context and ownership. The goal is not a static checklist; it is a repeatable process that improves your posture over time.
Check metadata
Understanding the finding in operational terms
One or more IAM access keys have exceeded your 90-day rotation target. In practice, this finding usually appears when baseline controls are implemented inconsistently across accounts, workloads, or teams. It can remain hidden for long periods because infrastructure drift happens gradually and ownership is often split between platform and application groups.
Treat this check as a control signal, not just a point-in-time warning. If the same issue appears after every deployment cycle, you likely need stronger preventive guardrails in infrastructure-as-code and review pipelines. Fast remediation is important, but durable prevention is what protects engineering velocity.
Risk impact and business implications
Security impact
Older static keys increase breach dwell time and often persist in scripts long after ownership changes. Findings in this category often sit on critical attack paths, so delayed remediation can compound risk.
Operational impact
Unresolved controls increase incident response load and create repeated triage work for the same root cause. Teams lose time on reactive cleanup instead of planned hardening.
Trust impact
Customers, auditors, and procurement teams increasingly ask for concrete evidence around cloud controls. Fixing and verifying this issue improves both security outcomes and external trust conversations.
Remediation steps for Access Keys Older Than 90 Days
- Inventory keys older than 90 days using IAM credential reports.
- Create replacement credentials or migrate to role-based temporary credentials.
- Update workloads, CI jobs, and local tooling to the new credential path.
- Deactivate old keys, monitor for breakage, then delete fully.
Verification workflow for reliable closure
- Confirm no active keys exceed policy age threshold.
- Audit CloudTrail for calls using deactivated key IDs.
- Re-run Posturio and verify iam.access_keys_older_than_90_days passes.
Verification should include both direct AWS configuration checks and scan-based confirmation. Combining these two methods catches false assumptions early and gives your team stronger evidence for internal or external reviews.
Access Keys Older Than 90 Days FAQs
Can I rotate keys without downtime?
Yes. Use a dual-key overlap window and cut over consumers before deactivation.
Is 90 days mandatory?
It is a common policy baseline; align timing with your security standard.
Is key rotation enough?
Rotation helps, but long-term improvement comes from replacing static keys with temporary role credentials.
How do I verify access keys older than 90 days is fully remediated?
Re-run your scan and confirm iam.access_keys_older_than_90_days passes, then review AWS configuration directly to validate persistence.
