What is SCADA?What is SCADA?
SCADA systems were first used in the 1960’sThe acronym SCADA means supervisory
control and data acquisitionSCADA systems are used to monitor and
control plant or equipment in industries such as: Telecommunications Energy, oil and gas refining Transportation Water and Wastewater monitoring and control

What is SCADA What is SCADA cont.cont.
SCADA systems can be relatively simple, such as ones that monitor environmental conditions of a small office building, or very complex, such as systems that monitor the activity in a nuclear power plant or control a municipality’s water system through tank, pump, and well control.
What is SCADA What is SCADA cont.cont.
SCADA systems gather information such as:
Pump Runtimes FlowWater Levels PressureAmperage Temperature
…and transfers and stores the information back to a central site (computer).
What is SCADA What is SCADA cont.cont.
SCADA systems can monitor specific alarm setups such as:
● Phase Loss● High Temperature● Excess Pump Starts● Analog Thresholds
● High or Low Level ● Pump Failure● Intrusion ● Power Loss ● Generator Running

Why the need?Why the need?
Why the need?Why the need?Ever increasing regulatory restrictions are
being imposed on Water and Wastewater operators for efficient & safe system operations such as Class 1 Reliability (EPA, DEQ, etc)
Both current & historical data from electronic databases greatly simplify the regulatory reporting process
Redundancy to larger SCADA systems all ready in place
The tank does that all the time. It’s OK.
ApplicationsApplications
National Public Wireless Data Networks combined with Internet Data Access are now a
permanent contender for automation in the Water & Wastewater Industry.

SCADA SecuritySCADA Security
Security TerminologySecurity Terminology 1. Redundancy of the system. Redundancy refers to the ability of
certain components of a system to assume functions of failed components without adversely affecting the performance of the system itself.
2. Robustness of the system. Robustness refers to the degree of insensitivity of a system design to errors in the estimates of those parameters affecting design choice. Robustness or those properties that make the system less vulnerable to attack (stability).
3. Resilience of the system. Resilience is the ability of a system to operate close to its closest possible design technically and institutionally over a short run after an attack, such that the losses are within manageable limits.
Ways to Prevent AttacksWays to Prevent Attacks
Should My System Use SCADA?Should My System Use SCADA? Today’s SCADA systems are able to take advantage of the evolution from mainframe
based to client/server architectures. These systems use common communications
protocols like Ethernet and TCP/IP to transmit data from the field to the central
master control unit.
SCADA protocols have also evolved from closed proprietary systems to an open system, allowing designers to choose equipment that can help them monitor their unique system using equipment from variety of vendors
SCADA systems are widely used to monitor and control U.S. critical infrastructure utilities such as Electrical Power Plants and Water Distribution Centers
While SCADA protocols are more open today, there is no clear consensus of which protocol is best. IEC 60870-5 series and DNP3 have many similarities but are not 100% compatible.
SCADA systems, like other computer systems, are subject to many common security
attacks such as viruses, denial of service, and hijacking of the system
Because SCADA systems use leased telephone lines, twisted pair cable, microwave radio, and spread spectrum techniques, they have many of the same security vulnerabilities

The Explosive Growth In National Wireless Networks, Personal Communications, and the Internet Provide Great Flexibility and Scalability For Automation Of Water and Wastewater Applications
No Need For Large Capital Outlay for Proprietary Wireless Network Build-out
Can Be Cost Effective and Deployed in a Variety Of Applications- Rural, Suburban, and Urban Sites- High Cost Sites- Applications that Require Redundancy- New Installations, Upgrades, and Replacement Sites
