Will the rules in the security group be deleted along with the security group itself?

The answer is that the rules in the security group are not retained once the security group itself is deleted. When you delete a security group, all associated rules that define inbound and outbound traffic policies are removed. This action is a part of ensuring that there are no lingering configurations that could impact other resources or create security holes.

Understanding this concept is vital for managing cloud environments effectively. Security groups are designed to control access to resources, and their rules are specifically tied to their lifecycle. Therefore, when a security group is terminated, its rules are automatically purged, which prevents any mistakenly retained permissions or rules from impacting your cloud security posture.

While other options suggest different conditions under which rules might be retained or depend on additional factors, the standard operation across most cloud platforms is that rules do not persist after the security group is deleted.
