CreateSecurityGroup - Elastic Compute Service - Alibaba Cloud ドキュメントセンター

Creates a security group. By default, a security group allows only instances in the security group to access each other. Access requests from outside the security group are denied. If you want to allow requests over the Internet or from instances in other security groups, you can call the AuthorizeSecurityGroup operation.
