TRITON/TRISIS Cyberattacker Has a New Target: Power Sector

XENOTIME, a cyberthreat activity group thought responsible for TRISIS/TRITON malware attacks on safety instrumented systems (SIS) at an oil and gas Middle Eastern facility in 2017, has been probing power company networks in the U.S. and elsewhere, new intelligence from industrial control systems (ICS) security firm Dragos shows.  “In February 2019, Dragos identified a change in […]

Equipment Showcase: Valves, Pipes, and Fittings

Proper valves, pipes, and fittings are important for the successful operation of power generation facilities. This equipment includes products with versatile designs to establish effective joining and sealing

Wireless Monitoring Improves Power Plant Operations

Wireless pressure gauges keep nine continuous emissions monitoring systems operating reliably, and wireless position monitoring helps close the loop on 90 control valves. Existing operations in power plants

Utility Group Under Congressional Investigation Will Disband

A utility industry coalition that has often challenged stricter air pollution and climate rules for power generation said it will dissolve. The Utility Air Regulatory Group (UARG), which has been under investigation from the House Energy and Commerce Committee due to its relationship with the Environmental Protection Agency’s (EPA’s) top air policy official and his […]

Modifying Behavior to Protect Systems in a Malicious Threat Landscape

The malicious threat landscape for industrial control systems (ICSs) is constantly evolving and getting more sophisticated, thereby raising the need to have visibility, implement protective controls, and perform continuous monitoring. As a result, it is important to take a look at the attack vectors of some malware/malicious events—such as Triton—that have occurred over the last […]

Certifying Precision Timing in the Smart Grid

Utilities deploying precise timing in their networks have an additional choice in evaluating solutions based on whether or not the devices are IEEE certified for compliance to the appropriate IEEE 1588 Power Profile. To reach this point, years of effort from the IEEE, International Electrotechnical Commission (IEC), National Institute of Standards and Technology (NIST), and […]

Proper Valve Trim Extends Life of Boiler Feedwater Valves

Boiler feedwater valves operate under severe service conditions and are subject to premature failure from seat leakage, cavitation, particulates, and frequent cycling. However, once the type and root cause of

Controlling Boiler Level When Operating Conditions Change

The right level instrumentation is key to keeping boilers on an even keel. Guided-wave radar offers a critical combination of capabilities. If asked to make a short list of factors able to improve heat rate

Working with Peers Is Critical to Power System Reliability [PODCAST]

When conversations around the power industry turn to computer hacking, more often than not experts say it’s not a question of if, but rather, how systems have been compromised. William Doering, adjunct professor in the online Master’s in Business Administration program at Maryville University and a director with Guidehouse—a management consulting services provider—said he has participated […]
