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.
