How to Investigate a Security Alert for a New Cloud Access Key

A new access key can support legitimate automation or create long-lived access outside normal interactive sign-in monitoring. The creator, permissions, and storage location determine how risky it is.

What to check

Review the creating identity, key scope and age, last use, associated deployment, secret storage, and activity after creation. Compare with approved change records and check whether the key belongs to a human or service account.

Recommended next step

Revoke unauthorized keys and investigate their use. For approved automation, restrict permissions, store the key securely, set rotation ownership, and monitor for unused or unexpected access.
