How can the user see if a change was made?
Use Amazon EC2 to see if the security group was changed.
Use AWS Identity and Access Management (IAM) to see which user or role changed the security group.
Use AWS CloudTrail to see if the security group was changed.
Use Amazon CloudWatch to see if the security group was changed.
Explanations:
Amazon EC2 does not provide a way to track changes made to security groups. It allows users to view and manage security groups but does not log or provide history of modifications.
AWS Identity and Access Management (IAM) controls access and permissions but does not track changes made to resources like security groups. It does not log the activity or modifications directly.
AWS CloudTrail logs API activity, including changes to security groups, such as modifications, deletions, or updates. By reviewing CloudTrail logs, users can see if and when changes were made to the security group.
Amazon CloudWatch is used for monitoring and logging metrics, not for tracking resource changes like security groups. CloudWatch does not record configuration changes or actions taken on resources like security groups.
