Russian Cyber Attacks on Critical Infrastructure: The “New Normal”
Concerns about Russian cyber attacks on U.S. electric utilities have increased again this week. The Wall Street Journal is reporting that such attacks have impacted hundreds of victims, not just the dozens reported earlier.
This news brings a new wave of concern about cyber attacks across the U.S. and beyond. If you are involved in this discussion, following is a recap of what is known about the Russian cyber attacks and my thoughts on its significance and repercussions.
Thwarting a Power Grid Control Center Cyberattack
Based on recent reports of Russian involvement in a multistage intrusion of the US power grid, it’s no longer a question of “if” threat actors will gain access to critical infrastructure control systems – it’s when it will happen again, and for what purpose.
What can be done to thwart these potentially disruptive assaults?
Russian Cyberattacks on Critical Infrastructure – What You Need to Know
The U.S. government has just released an important cyber security alert that confirms Russian government cyberattacks targeting energy and other critical infrastructure sectors.
The cyber campaign described is not new however, rather it is likely an expanded version of the Dragonfly 2.0 playbook. The Nozomi Networks solution ships today with an analysis toolkit that identifies the presence of Dragonfly.
Advancing ICS Cyber Security for Low-Impact Electricity Carriers
Cyber security threats to the power grid are a continuous danger nowadays, and because of this, regulation in North America may expand from covering bulk electricity carriers to low-impact carriers. Last month FERC, the U.S. Federal Energy Regulatory Commission, proposed a new rule for low-impact carriers, covering transient electronic devices such as USBs and laptops, and incident response policies.
While the regulation is still in the review stage, some low-impact utilities are not waiting to improve their cyber security posture and get a head start on compliance. They are taking advantage of the latest innovation for cyber threat monitoring and detection systems. Vermont Electric Coop is one such entity, and they have realized multiple benefits from their proactive approach.
Securing Substations and Power Grids with ICS Anomaly Detection
One of the findings of the recent SANS report “Securing Industrial Control Systems – 2017” is that the number one technology industrial organizations are looking to implement over the next 18 months is intrusion detection.
Up until recently, detecting anomalies on ICS networks that might be caused by a cyberattack has been ”mission impossible.” That’s because such networks typically include equipment from a wide assortment of vendors, run thousands of real-time processes and generate huge volumes of data. Analyzing and monitoring this data to detect anomalies was very difficult.
The good news is that a new generation of ICS cyber security tool is available for industrial intrusion detection. This article describes how our product, SCADAguardian does it, and gives an example of how it would detect and counter a cyberattack on a regional control center of an electric power utility.

SCADA Cyber Security for an Industry 4.0 Oil and Gas Application
If you’re boots-on-the-ground dealing with the daily oil and gas challenges of control and automation, you’ve likely heard lots about Industry 4.0, the fourth wave of industrial revolution. Given the inter-connection between more and more devices and commercially marketed systems, the cyber security challenges of this phase of automation are daunting.
To overcome these hurdles, let’s examine how an application that’s been around for a long time – hosted SCADA, can be monitored for cyber security, data integrity and reliability.
Improving ICS Cyber Security for Pipeline Systems
In the last decade market and cost pressures have driven significant technological advances in automation and industrial connectivity across all aspects of petroleum extraction, pipeline transport and refining. While technological advances are delivering business benefits, systems are now exposed to more cyber risks than ever before.
Yet, according to a 2017 survey by the Ponemon Institute, the deployment of cyber security measures in the oil and gas industry isn’t keeping pace with the growth of digitalization in operations.
One way to overcome the ICS cyber security gap is to utilize next generation technology that leverages machine learning and artificial intelligence (AI) to deal with system complexity and deliver immediate benefits. Let’s take a look at two examples of how a passive ICS anomaly detection and monitoring solution secures pipeline networks.
ICS Security Lags Digitization in U.S. Oil and Gas Industry
A recently released study by the Ponemon Institute finds that 61% of oil and gas operators in the U.S. indicate that their organization’s ICS protection and security is inadequate. While the implementation of digitally connected industrial components is delivering business benefits, it has significantly increased cyber risk. Yet only 41% of companies continually monitor OT infrastructure to prioritize cyber threats and attacks.
