By the
actions of the 16years of real-time process power as well as the SCADA
industry understanding, the industrial defender has calculated a
security submission from the SCADA also known as the Process control
environment.
The industrial advocate consultants provide a full series of risk
evaluation projects. The team has done more than 60 individual process
control and SCADA system assessments, this is much more assessments
than any other company that has been specified to the SCADA or also
known as Process Control RT.
Every aspect of SCADA is based on a solution that is built to help with
every function in the gas industry, from basic functions to the process
and control of the SCADA environment.

The brain of SCADA
system lies in Remote Terminal Units (also termed as RTU). Remote
terminal units are composed of logic converters which can be programmed
easily. Remote terminal unit is generally set as per the requirements,
but mostly RTU requires human intervention in case of emergency or any
extreme conditions. But in general, most of SCADA system behaves as
closed loop systems thus require minimal human intervention.
One of key features about SCADA systems is their ability of real time
monitoring of entire system. This is accomplished by data acquisitions
from sensors viz meter reading, status of sensor etc that are sent to
central system at regular time period depending upon the system. Along
with data acquisition another function performed by SCADA system is to
display the data collected from various sensors in human readable
format so that any time human can intervene as the need
arises. |

SCADA
systems, acronym for Supervisory Control and Data Acquisition systems
are supervisory systems that have made automated tasks more reliable
and efficient without having need of human to intervene or handle any
stage of process.
Thus, SCADA systems are also known as closed loop systems as they
operate of their own and response to change in parameter value/ state
beyond permissible values. Also, there is always a possibility of human
intervention as per the need that provides flexibility to SCADA
systems. Due to high range of flexibility, reliability and efficiency
SCADA systems have found their applications in control systems
(electricity control systems, water sewerage systems), radio
transmissions (long distance Scada GSM).
Even daily routine equipments have not left untouched by this
tremendous technology and many SCADA compatible equipments like water
metering pumps have flooded markets.
