Description

Classic Load Balancer (ELB) provides basic load balancing across multiple Amazon EC2 instances and operates at both the request level and connection level. The load balancer {AwsEc2Elb} was discovered to be associated with a security group {AwsEc2Elb.SecurityGroups} that allows public ingress access without IP filtering (0.0.0.0/0). Load balancer configured with public access opens the application hosted behind the load balancer to attacks from malicious entities on the Internet.
