Port 53 (DNS) Open to the World

This bot identifies when a Resource Access List is created whether it allows unrestricted access (0.0.0.0/0) to TCP/UDP port 53.

Unrestricted access increases your infrastructure attack surface and can create opportunities for theft of data, loss of data, or hacking.

Recommended Action

Modify the Resource Access List to prevent unrestricted access. If the port is intended to allow unrestricted access, then consider additional security measures to secure your infrastructure such as IP tables.
