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.
SCADA
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
