Testing Scada Networks
SCADA is of course the protocol that utilities such as gas, electric, and telecoms use to control the equipment they have to manage. Think of a simple way to check a temperature or voltage reading and report back as well as set values on switches, pumps, etc. It’s easy. In the olden days SCADA devices were connected by phone lines and dedicated circuits. Today of course they are connected to IP networks that are often also connected to the Internet. Just to get a feeling for the type of device that can be controlled via SCADA check out this awesome movie of an electrical gate being tripped.
