Scenarios

Both default and custom security groups are free.

Notes and Constraints

• The default security group is named default and cannot be deleted.

• If you want to delete a security group that is associated with instances, such as cloud servers, containers, and databases, you need to remove the instances from the security group first. For details, see Adding an Instance to or Removing an Instance from a Security Group.

  If you want to know the instances associated with a security group, refer to How Do I Know the Instances Associated with a Security Group?

• A security group cannot be deleted if it is used as the source or destination of a rule in another security group.

  Delete or modify the rule and delete the security group again.

  For example, if the source of a rule in security group sg-B is set to sg-A, you need to delete or modify the rule in sg-B before deleting sg-A.
