// Creates a security group. A security group acts as a virtual firewall for your
// instance to control inbound and outbound traffic. For more information, see
// Amazon EC2 Security Groups
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-network-security.html)
// in the Amazon Elastic Compute Cloud User Guide and Security Groups for Your VPC
// (https://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_SecurityGroups.html)
// in the Amazon Virtual Private Cloud User Guide. When you create a security
// group, you specify a friendly name of your choice. You can have a security group
// for use in EC2-Classic with the same name as a security group for use in a VPC.
// However, you can't have two security groups for use in EC2-Classic with the same
// name or two security groups for use in a VPC with the same name. You have a
// default security group for use in EC2-Classic and a default security group for
// use in your VPC. If you don't specify a security group when you launch an
// instance, the instance is launched into the appropriate default security group.
// A default security group includes a default rule that grants instances
// unrestricted network access to each other. You can add or remove rules from your
// security groups using AuthorizeSecurityGroupIngress,
// AuthorizeSecurityGroupEgress, RevokeSecurityGroupIngress, and
// RevokeSecurityGroupEgress. For more information about VPC security group limits,
// see Amazon VPC Limits
// (https://docs.aws.amazon.com/vpc/latest/userguide/amazon-vpc-limits.html).
