Creates a new security group. Group names must be unique per account.
Every instance is launched in a security group. If no security group is specified
during launch, the instances are launched in the default security group. Instances
within the same security group have unrestricted network access to each other.
Instances will reject network access attempts from other instances in a different
security group. As the owner of instances you can grant or revoke specific
permissions using the AuthorizeSecurityGroupIngress and RevokeSecurityGroupIngress operations.
For more information about security groups, go to Security Groups in the Amazon Elastic Compute Cloud User Guide.
