Multi-factor authentication is held up as a 'silver bullet' for protecting remote access systems, but Pulse VPN MFA was just breached. What does this mean for industrial security?
The threat environment continues to evolve with Russian Sandworm group breaching Centreon monitoring system installations with targeted attacks. New blog post by Andrew Ginter
The High-Tech Association of the Israeli Manufacturers Association has named Lior Frenkel, co-founder and CEO of Waterfall Security Solutions, to lead a newly established Cyber Companies Forum. Read more
Industrial/OT cybersecurity programs include people, processes and technology. We often talk about our technology, unidirectional security gateways, here, but that technology alone is not all that is needed. A full program includes all the elements from the NIST framework. Click here to explore secu
There are voices in the industrial security community advocating a return to hard-wired protective relays, discarding two decades of progress in this space. But, a practical solution is to protect the protection. In power plants, as in high voltage substations, protective relays can be connected to
Critical infrastructure OT equipment directly connected to the Internet is the focus of the just-issued and very long NSA/CISA AA20-205A alert. Surprises: this is the first alert recommending a manual-ops fall-back plan (resilience) and a tamper-proof repository for "gold" images (to use during manu
Honda shut down a number of manufacturing facilities on Monday June 8, 2020, with most, but not all facilities back up again Tuesday. The (unconfirmed) cause appears to be an infestation by the “Snake” ransomware
The US government acts to protect the electric grid - but there is only so much any government can do. Unlike physical conflicts, the only way to defeat the most sophisticated cyber attacks is for individual sites to take the lead
In this time of COVID-19 travel restrictions and quarantines, understanding options for safe, secure remote access to Industrial Sites and Control Centers is especially important. This post reviews 3 common options for secure remote access and support: server replication, Remote Screen View and Secu
The US DHS CISA just issued an alert describing a natural gas compression facility hit by ransomware. The alert recommends segmentation; the most robust segmentation is unidirectional. Read more why OT network segmentation is so important and how it should be done
How would Iran launch a cyber retaliation? Would they fly operatives into the country, drive up to power plants and cut through barbed-wire perimeters with USB drives? No - they will use their zero-days and custom malware remotely, sipping coffee in the safety of their offices. Several jurisdictions
In a recent Industrial Security podcast, Patrick Miller was asked about IT vs OT approaches to security. He replied, “We've always characterized it in terms of OT and IT
FireEye reports that the Triton (aka Trisys) malware targeting safety instrumented systems has been discovered at another undisclosed target in the Middle East. As a result of investigating that intrusion, FireEye reports that the threat actors behind Triton are a government-sponsored Russian agency

The Carbon Black Quarterly Incident Response Threat Report for 2018 shows that destroying forensic evidence to hide attack sources and attack capabilities is becoming increasingly common. The report quotes an incident response professional as observing that “We’ve seen a lot of destruction of lo
“The beginning of wisdom is the definition of terms.” - Socrates (470 – 399 B.C.) Definitions are important - good ones shape our understanding of concepts while poor ones impair that understanding. Consider the definition: pen: a tube of ink with a tiny ball bearing at the tip How useful is
The Meltdown / Spectre saga continues. Ulf Frisk just posted a description of a vulnerability he has coined "Total Meltdown". It seems that Microsoft developers introduced an even worse vulnerability while fixing the Meltdown vulnerability in Windows 7 and Windows 2008 Server R2. With this broken Me
Consider a prolonged power outage over a large metropolitan area, or a cyber attack targeting a nuclear power plant. These are real attacks, not hypothetical ones, that affected people’s lives, and cost owners and operators both monetary and reputational damages. A key problem with modernization
A chronic complaint of industrial control system (ICS) security practitioners is under-funding, and funding decisions for security programs are frequently made by business decision-makers with a limited understanding of cybersecurity and cyber risk issues. Waterfall Security Solutions has just relea
The big news today is the Spectre and Meltdown bugs. These vulnerabilities let attack code such as Javascript steal passwords, encryption keys and session cookies from kernel memory and/or browser windows on nearly all modern computers. The performance hits and code changes needed to fix these bugs
Recent reports of cyber attacks on U.S. nuclear reactors have brought upon public doubt on the strength of cyber protections at nuclear power plants. The response from nuclear plants has resoundingly been "no need to panic, nothing to see here," but other pundits are saying "I’m not sure I believe
I recently attended the NERC CIP Emerging Technologies Round Table meeting on Cloud & IoT, where a primary focus was Bulk Electric System (BES) Cyber Systems in the cloud. BES Cyber Systems are systems with an adverse effect on the BES within 15 minutes of failure or compromise. Interestingly, t
A short while back, I was asked to speak at an event held by The Cyber Resilient Energy Delivery Consortium (CREDC), a research and development initiative funded by the U.S. Department of Energy. Its research focuses on cybersecurity and cyber-resiliency of energy delivery systems for the electric p
Recently, Waterfall joined 24 vendors from Industrie 4.0 (I4.0) and the Industrial Internet Consortium (IIC) in demonstrating secure cloud interconnectivity at the Hannover Messe industrial event. Unidirectional gateway technology and strong encryption was at the heart of this outsourced security de
This is a question that might not even emerge initially in the minds of IT security professionals. However, when we take a closer look, the differences are clear. Consider the history of IT and SCADA networks. The original "killer app" for IT networks was mainframe transaction processing. The origin
