- 2. SCADA Supervisory control and data acquisition systems (SCADA)
- 3. SCADA stand for "Supervisory Control and Data Acquisition Systems". It is basically a software or it is a computer graphics install in computer to control any process. SCADA is an industrial computer-based control system employed to gather and analyze the real-time data to keep track, monitor and control industrial equipment's in different types of industries. SCADA systems, providing centralized monitoring and control of a plant's field sites. SCADA
- 4. • SCADA systems collect data from a primary system in order to control that primary system. • This is done through the use of various hardware devices such as Programmable Logic Controllers (PLC's) that are installed in various locations or through the use of specialized software. • SCADA is an industrial software it is user-friendly front-end to a control system, that easily communicate with PLCs. • SCADA software's are very useful to monitor and analysis of historical as well as new data. • It allow remote monitoring and controlling of various plant • operations in real time basis. • SCADA systems are generally used in automation industries along with PLCs.

- 6. 1st generation (1970s). Co-located control:- Controlled units were on the same site as the controlling computer with hard-wired connections between them. No network so no potential for external attack. Very limited chance of insider attack operation by teams rather than SCADA GENERATIONS
- 7. 2nd generation (1980s/90s) Distributed control:- SCADA systems networked with devices using special-purpose protocols No external network connection Vulnerable to insider attacks because of distributed sites SCADA GENERATIONS
- 8. 3rd generation (2000s) Networked systems:- SCADA systems no longer isolated but connected to external networks External connection through computers (particularly PCs) that are directly connected to the Internet More use of standard protocols such as TCP/IP for communications Remote system monitoring and upgrades from providers requires network connection SCADA GENERATIONS
- 9. A SCADA system performs four key functions:- Data acquisition from PLCs and RTUS Unit control Networked data communications with PLCs and other systems Data presentation for system operation SCADA FUNCTIONALITY
- 10. • Supervisory control and data acquisition (SCADA): A subset of ICS, SCADA is used to manage distributed systems, such as • Water distribution • Electrical utility transmission • Rail and other public transportation • Oil and natural gas pipelines SCADA FEATURES
- 11. • Industrial control system (ICS): Using an array of technology and protocols, ICS controls include management of • Industrial processes • Delivery of electricity • Delivery of water • Processing of wastewater • Delivery of natural gas SCADA FEATURES
- 12. • Human-machine interface (HMI): The HMI is the interface used by humans to interact with ICS and SCADA systems and devices. It is the portal to the ICS/SCADA supervisory computers used for monitoring and control. SCADA FEATURES
- 13. SCADA System Working:- • The SCADA system performs the following functions • Data Acquisitions • Data Communication • Information/ Data presentation • Monitoring/ Control SCADA
- 14. • Examples of SCADA Security:- The threats that occur in SCADA systems include the following. • Hackers • Terrorists • Malware • Error Inside • The weakness of SCADA security mainly occurs because of the following reasons. • Poor Training • Loopholes Development of App • Issues while Monitoring • Less Maintenance SCADA
- 15. • Generation and Distribution of Power • Public Transport • Water and Sewage System • Manufacturing • Industries & Buildings • Communication Networks • Oil & Gas Industries • Power generation, transmission, and distribution • Water distribution and reservoir system • Public buildings like electrical heating and cooling system. • Generators and turbines • Traffic light control system SCADA APPLICATION
- 16. • The quality of service can be improved • Reliability can be improved • Maintenance cost is less • The operation can be reduced • Large system parameters can be monitored • Manpower can be reduced • Repair time can be reduced • Fault detection & fault localization • It stores a large amount of data • As per the user requirement, it displays the data in various formats. SCADA ADVANTAGES
- 17. • It is complex in terms of dependent modules & hardware units. • It needs analysts, programmers & skilled operators to maintain • High installation cost • Unemployment rates can be increased • This system supports hardware devices and restricted software’s SCADA DISADVANTAGES
