Reduce the probability of a breach by checking EC2 security groups for inbound rules that allow unfettered access to TCP port 443 (used by HTTP) and restrict access to IP addresses that require this port.
Malicious activity, such as denial-of-service (DoS) attacks and hacking, can occur when permitting unfettered access to this port.
Follow the Security group rules docs to learn how to add a security group rule that will restrict access to a specific port.
revoke-security-group-ingress to remove inbound rules that allow unrestricted access to port 443.
aws ec2 revoke-security-group-ingress --group-name your-group-name --protocol tcp --port 443 --cidr 192.0.2.0/24
authorize-security-group-ingress to add new inbound rules that restrict TCP access.
aws ec2 authorize-security-group-ingress --group-name your-group-name --protocol tcp --port 443 --cidr 192.0.2.0/24
