What Is Listening?

Aurora's firewall was configured years ago and never reviewed. You are given the current inbound rule set and a connection snapshot from the edge. Identify what each rule actually exposes, and find the one exposure that should never face the internet.

What you will be able to do

  • Map ports to the protocols and services behind them.
  • Read a connection snapshot as IP + port + protocol together.
  • Identify the dangerous internet-facing exposure.
