Delete Unused AWS EBS Volumes

Risk level: Medium

Rule ID: EBS-001

An Amazon Elastic Block Store (EBS) volume is distinct from the lifecycle of its associated Amazon Elastic Compute Cloud (EC2) instance. EBS volumes are attached to EC2 Instances as storage devices. By default, unless you select the “Delete on Termination” option during instance launch, terminating the EC2 instance will only detach the EBS volume, not delete it. In dynamic development and testing environments where EC2 instances are frequently launched and terminated, this can result in an accumulation of idle EBS volumes. These unused volumes incur charges in your AWS account, even when they’re not in use. To improve cost efficiency, it’s essential to eliminate these unused volumes. Additionally, deleting inactive EBS volumes is a crucial security measure to prevent unauthorized access to any sensitive data that might be stored on them.

Rule EBS- 001 checks whether there are unused EBS Volumes in your AWS account. This rule can help you with the following as well:
