Collision Domain

An ICS unit that can operate as a stand-alone device, be networked together with other SCADA systems, or be networked with traditional IT systems. Most SCADA systems are designed with minimal human interfaces. Often, they use mechanical buttons and knobs or simple LCD screen interfaces (similar to what you might have on a business printer or a GPS navigation device). However, networked SCADA devices may have more complex remote-control software interfaces.
