Which of the following signs is not an indicator of an AWS-based security incident?

The creation of authorized IAM users, roles, keys, resources, and policies within an AWS organization account does not indicate a security incident. This activity typically reflects legitimate administrative tasks performed by authorized personnel for managing access control and resource management in an AWS environment. Organizations must regularly create and update IAM users and permissions to ensure that they follow security best practices, such as adhering to the principle of least privilege.

In contrast, unauthorized access attempts from unknown IP addresses, modification of security group rules that allow public access, and deletion of critical logs in AWS CloudTrail represent suspicious activities that could indicate malicious behavior or a security breach. Each of these actions typically signifies a compromise or a potential risk to the security posture of the organization, warranting further investigation.
