A. Create a security group with a rule that denies inbound connections from 0.0.0.0/0 on port 80. Attach this security group to the ALB to overwrite more permissive rules from the ALB’s default security group.
B. Create a network ACL that denies inbound connections from 0.0.0.0/0 on port 80. Associate the network ACL with the VPC’s internet gateway.
C. Create a network ACL that allows outbound connections to the VPC IP range on port 443 only. Associate the network ACL with the VPC’s internet gateway.
D. Create a security group with a single inbound rule that allows connections from 0.0.0.0/0 on port 443. Ensure this security group is the only one associated with the ALB.
