  name        = "web-servers-sg"
  description = "Security group for web servers"
  vpc_id      = "vpc-123456"

  ingress_cidr_blocks = ["0.0.0.0/0"]
  ingress_rules       = ["http-80-tcp", "https-443-tcp"]

  egress_rules = ["all-all"]

  tags = {
    Environment = "production"
    Terraform   = "true"
  }
}
