PNM Sensor Security - UFW

This is the first in a series of videos where I go over ways to secure your PNM Sensor. In this video we are using the Uncomplicated Firewall wrapper to enable the Ubuntu Firewall and limit traffic to just the ports we need to manage the device and accept telemetry from all our exporters.
Remember that the PNM Sensor is a Linux Ubuntu Server and needs to be secured just like any device on your network.
