All the SCADA systems irrespective of field where they implied rely on same principle. These systems are employed for remote management of critical processes.

These systems have central room/system to manage all these processes with the help of computers and communication networks. The remote sensors collect the data at specific interval of time which is predefined and then sends this data to central system which processes the data collected.

Thus, main components of SCADA system can be zeroed into three components: Hardware (for input and output), PLCs (Programmable Logic Converters, which determines the responses SCADA system issues when some error is detected) and Transmission media (through which data collected is sent to central system through remote terminals). Though various modes of media are used like Ethernet, internet or wireless but radio transmission has always been cost effective solutions.

Generally SCADA design engineers never show any concern about the security as well as authentication in the design of SCADA system, its deployment along with currently working SCADA networks.

Thus, many leakages prevail and hackers can take advantage of these loop holes which can lead to leakage of crucial data or huge financial losses. SCADA systems are also employed in nuclear electricity generation and leakage of such data can be a costly affair if it gets into wrong hands. This gives another reason for researchers to call for security enhancement for SCADA communication protocols.

There is no doubt about the fact that SCADA networks are physically secure. Thus, SCADA design engineers never pay any heed to make the transmission secure.

There can be SCADA Programmer which is able to carry programming of logic converters of SCADA systems. The job profile will include configuration and programming of automation and various control systems including Human Machine Interface (abbreviated as HMI), or Man machine interface (abbreviated as MMI) or even SCADA systems.

To see yourself in profile of SCADA engineer job profile, you need to be well versed in certain type of software packages which are of great importance in this field as they are used for doing programming. Common software employed are Wonderware, Intellution, Rockewell, Iconics. Ci-tech etc.

Also you need to be sound in Boolean logic, data logging, symbol conventions along with tagging convention. Generally the positions for SCADA engineers seek people having nice hand at Visual Basic Programming, reporting packages, alarming with external paging.
