AWS Security Hub, a cloud security posture management service that performs security best practice checks, aggregates alerts, and facilitates automated remediation, now features a detailed history of changes that have occurred for each finding in your environment. This view provides an immutable trail of changes, indicating what fields were changed, by whom, and when. You can now get more visibility into the changes made to your findings over time, making it easier to identify and investigate any suspicious or unauthorized changes.
