The importance of up-to-date critical system monitoring
BY MARLEE ROSEN, Rosen Associates
Supervisory control and data acquisition (SCADA) networks contain computers and applications that perform critical capabilities in delivering essential services and commodities (for example, electricity, natural gas, water, waste treatment, wind farms, transportation) to consumers. As such, they are part of America’s critical infrastructure and require protection from a variety of threats that exist in cyber space and even more commonly today, the mentality that “if it isn’t broken then don’t fix it”.
To optimize the collection and analysis of the data and control of equipment such as pumps and valves from remote locations, SCADA networks provide great efficiency and are widely used but many have been set up roughly 15 years ago and left to run without any further concern for product updates or enhancements.
MITIGATE RISK
These legacy SCADAs present a tremendous security risk. SCADAs were initially designed to maximize functionality and automate processes, product updates and new revisions. However, SCADA companies merged, ceased to exist or evolved more into manufacturing execution systems (MES). Also, tremendous changes have occurred in the automation industry that have left multitudes of outdated SCADAs in the field. As a result,...
