Supervisory Control and Data Acquisition (SCADA) Systems for Command, Control, Communications, Computer Intelligence, Surveillance, and Reconnaissanmce (C4ISR) Facilities Date
The computer technology is also referred to as SCADA/EMS or EMS/SCADA. In these respects, the terminology EMS then excludes the monitoring and control functions, but more specifically refers to the collective suite of power network applications and to the generation control and scheduling applications.
In smaller SCADA systems, the supervisory computer may be composed of a single PC, in which case the HMI is a part of this computer. In larger SCADA systems, the master station may include several HMIs hosted on client computers, multiple servers for data acquisition, distributed software applications, and disaster recovery sites.
The security of IEC 104, by design has been proven to be problematic, [2] as many of the other SCADA protocols developed around the same time. Though the IEC technical committee (TC) 57 have published a security standard IEC 62351 , which implements encryption tunneling and network monitoring in an effort to address attacks such as packet ...
The IEC Technical Committee 57 (Working Group 03) have developed part 6 to provide a communication profile for sending basic telecontrol messages between two systems which is compatible with ISO standards and ITU-T recommendations.
Worldwide Industrial Telemetry Standards (WITS) is a suite of communications protocols designed for use within the public utility industry between components of a SCADA system. It was developed for communications between a WITS Master Station and its remotely connected WITS Field Devices (for example, Remote Telemetry Units ).
The OPC Data Access Specification is the first of a group of specifications known as the OPC Classic Specifications. [1]OPC Data Access is a group of client–server standards that provides specifications for communicating real-time data from data acquisition devices such as PLCs to display and interface devices like Human–Machine Interfaces (HMI), SCADA systems [2] and also ERP/MES systems.

The DNP3 protocol is also referenced in IEEE Std. IEEE 1379-2000, which recommends a set of best practices for implementing modern SCADA Master-RTU/IED communication links. These include not just encryption but other practices that enhance security against well known intrusion methods.
