Elastic Compute Service:DeleteSecurityGroup

Last Updated:Apr 11, 2024

Deletes a security group.

Operation description

Usage notes

Take note of the following items:

  • Before you delete a security group, make sure that the security group does not contain instances and is not referenced by other security groups. Otherwise, the DeleteSecurityGroup request fails. You can call the DescribeSecurityGroupReferences operation to query the reference details of the security group.
  • If the InvalidOperation.DeletionProtection error code is returned when you call the DeleteSecurityGroup operation to delete a security group or if a deletion protection-related message appears when you delete a security group in the Elastic Compute Service (ECS) console, the deletion protection feature is enabled for the security group. When you create a Container Service for Kubernetes (ACK) cluster, the deletion protection feature is enabled for an associated security group to prevent accidental deletion. You cannot manually disable the deletion protection feature for the security group. The deletion protection feature can be automatically disabled only after the ACK cluster is deleted. For more information, see Disable deletion protection for a security group.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.
