The instance is directly addressable from the internet, so its exposure rests entirely on the security group being right.

01

Detect

ZopNight checks this automatically across AWS, with read-only access to the account.

02

Explain

Every finding says exactly what to change: Remove the public IP from EC2 instance.

03

Fix

The finding opens with the fix already written out, step by step, so it is one ticket, not an investigation.

Applies to
EC2 Instances on AWS
The fix, by hand
  1. Confirm whether anything dials this instance directly from the internet (DNS records, monitoring probes, customer integrations).
  2. If inbound public access is required, terminate this instance and re-launch behind an Application Load Balancer in a public subnet, with the instance in a private subnet.
  3. If only outbound internet access is needed, move the instance to a private subnet with a NAT Gateway or VPC endpoints.
  4. If no internet access is needed, disable AssignIpv6 / public IPv4 on the network interface.
  5. Validate end-to-end (app smoke tests, monitoring probes) before the next prod release.

These are the steps the finding carries in the product.
