Acquisitionsserver

Back 1

acquisitionsserver An ICS server that collects and stores raw data. This serverconnects to field devices from which it receives the raw data andpasses that information on to other servers in the SCADA system.

Back 8

Oneof two methods that an ICS might use to control the physical system.In a closed loop system, decisions are made based on real-time data.Also called a closed network.

Front 9

Computerforensics

Back 9

Theprocess of investigating deeper data on a computer, essentiallyperforming an autopsy on the computer to discover hidden data, suchas deleted files and file fragments, and who has accessed that dataand when.

Back 14

Thecommunication channel that connects a PLC to an RTU (when these areseparate devices) or to an actuator.

Front 15

Historian

Back 15

AnICS server that stores a centralized database of collected andanalyzed data and control activities. This data is often analyzed torecognize trends in the physical system

Front 16

Back 16

(human-machineinterface) A computer, including hardware and software, thattechnicians use to monitor and manage physical systems in anindustrial system.

Front 17

Hot/Warm/ColdSite

Back 17

coldsite -A place where the computers, devices, and connectivity necessary torebuild a network exist, but are not appropriately configured,updated, or connected to match the network’s current state.

hotsite -A place where the computers, devices, and connectivity necessary torebuild a network exist, and all are appropriately configured,updated, and connected to match a network’s current state.

warmsite -A place where the computers, devices, and connectivity necessary torebuild a network exist, though only some are appropriatelyconfigured, updated, or connected to match the network’s currentstate

Front 18

ICSserver

Back 18

Aserver in an ICS or SCADA system that might include an acquisitionsserver, which collects and stores raw data, a supervisory server,which controls the physical system, or a historian, which is acentralized database of collected and analyzed data and controlactivities.
