Modern technology begets modern threats
November 14, 2008

As SCADA and networked systems become more common inside critical facilities like water and wastewater treatment plants, the need to ensure the security of those electronic control systems becomes even more important. Variable-frequency drives (VFDs) and programmable-logic controllers (PLCs) are frequently used in our lift stations and booster pump stations, and those are just two examples of high-tech pieces of the modern infrastructure puzzle. Attacks are not a commonplace occurrence yet, but disgruntled parties have used radio controls to cause pump station failures.
