Recent news regarding SCADA system intrusions has highlighted the security differences between network and s. SCADA system operators must assess vulnerabilities and implement security measures at both levels.
Human Machine Interface (HMI) has evolved significantly from the days when operations staff had to sit in front of a single screen to monitor a machine or a process. HMI/supervisory control and data acquisition (SCADA) applications now not only monitor and help control equipment and processes, but also provide a huge range of information regarding machine and plant operations.
Training of new employees is required for all businesses. For some jobs it may consist of an awareness followed by a gradual increase in duties and responsibilities or a complete boot camp approach in which one is educated on basic concepts and policies before taking on responsibility.
There is a trend in Enterprise SCADA toward larger systems controlling more assets from a single location within the pipeline company. As additional control systems are required for new assets, expansion of existing assets or projects to replace legacy systems, it is natural to want to leverage or expand an existing successful SCADA infrastructure.
In 2010, an incident in San Bruno, CA brought national attention to the oil and gas industry when a natural gas pipeline exploded in a residential neighborhood, leveling homes and claiming several lives. The resulting shockwave from the explosion was equivalent to a 1.1 magnitude earthquake.
SCADA migration projects are complex and filled with many challenges. When pipeline companies undertake these projects they are often focused on technical aspects such as selecting the right SCADA system, scoping and planning the conversion, establishing interface connectivity, and configuring the system properly.
Cybersecurity concerns with our critical infrastructures are well-known. In recent years, the Department of Homeland Security (DHS) and other authorities have encouraged critical infrastructure owners and operators to take steps to ensure cybersecurity for both their business and critical control system assets.
Supervisory control and data acquisition (SCADA) is a pivotal tool in achieving impressive productivity and reliability of pipelines. However, SCADA systems face cyber threats that could render them inoperable, causing substantial adverse effects on profitability. Worse yet, the threats could deactivate some safety systems, and jeopardize safety of the pipeline, workers and neighbors.
An Industrial Control System (ICS) is comprised of many disparate components, including hardware and software technologies, the system infrastructure–from the communications network to the physical plant–the human element for tasks that require manual intervention, and the environment.
