How to Review an Infrastructure Change That Opens a New Network Port

A planned firewall or security group change may expose a service more broadly than intended if its source range or destination is misunderstood.

What to check

Recommended next step

Narrow access to verified sources and record the reason and owner before applying. Informatix Systems can review infrastructure changes and cloud security posture.
