Change is prolific in organizations’ IT environments. Hardware assets change. Software programs change. Configuration states change. Some of these modifications are authorized insofar as they occur during an organization’s regular patching cycle, while others cause concern by popping up unexpectedly. Organizations commonly respond to this dynamism by investing in asset discovery and secure...

Which Flavor of the Purdue Model Should You Follow? If you enter the term "Purdue Model" into your favorite search engine, the resulting images will vary considerably. There's almost no better way to stir up an Operational Technology (OT) security conversation than to begin debating what belongs on Level 1 or Level 3 of the model. You might even find some diagrams place operator Human-Machine...

It seems that the most popular topics in cybersecurity for the last year have been zero trust as well as the convergence of Information Technology (IT) and Operational Technology (OT). These developments are good, as they signal some positive motion towards better overall security. Some of the current risks are worth noting, with a forward glance to protecting specific industries such as oil and...

In this episode, Patrick Miller , Founder of Ampere Industrial Security, discusses what utilities and other industrial companies need to consider when it comes to the goldmines of data they're collecting from their machines and customers. He also explains why security and privacy needs to be incorporated in these operations by design. https://open.spotify.com/episode/7cMR1D4nastJLUDE4VUXYm?si...

Throughout this blog series, I have examined real-world ICS cyber-related incidents as a way of looking back to predict what the next attack may look like. The three categories of attacker that I have considered so far are disgruntled insiders, ransomware groups, and APT. Knowing about past events, their impact, and how they unfolded can be critical for thwarting similar attacks in the future. As...

No discussion on ICS attacks could be complete without talking about what some would call, ‘the elephant in the room.’ Critical infrastructure has always been a target for warfare, and modern ICS are no exception. Several high-profile ICS disruptions have in fact been attributed to malicious hackers working at the behest of a military or intelligence agency. Looking at Examples of APTs The...

OT networks often rely on Windows systems for various ICS applications including HMIs, historians, and data gateways. Beyond that, they also commonly rely on Windows systems to run associated IT-networks . A successful ransomware deployment into either of these networks may prevent engineers from controlling plant operations and lead to an unplanned shutdown. This creates an immediate cost on the...

Often, the most critical threats come from within an organization itself. This is true for all sectors, but it is especially true for industrial control systems (ICS). Technicians in these environments already have access to plant controls and may have the deep knowledge of industrial processes needed to achieve specific goals. The damage caused by an insider may range from mild disruption to...

Faced with rows of empty gas pumps , many Americans on the East Coast may be wondering why this happened , whether it will happen again, or if there is anything we can do to avoid future catastrophe. The unpleasant truth of the matter is that this will certainly not be the last time society is disrupted due to attackers targeting critical industrial control systems (ICS). The impact of such an...

Over the weekend, the Alpharetta-based Colonial Pipeline was hit by an extensive ransomware attack that shut down its information technology (IT) and industrial operational technology (OT) systems. Simply put, an all-too-common ransomware event targeting IT systems encouraged a voluntary shutdown on the production side (OT) of the business to prevent further exposure. Colonial Pipeline is...

Lane Thames, PhD and principal security researcher at Tripwire explains the challenges you might not have considered in IT/OT convergence. https://open.spotify.com/episode/2w3lsuN3V1ZOiLVGqxw58v?si=5lVBp46tTiK7tfzmCnpeuA Spotify: https://open.spotify.com/show/5UDKiGLlzxhiGnd6FtvEnm Stitcher: https://www.stitcher.com/podcast/the-tripwire-cybersecurity-podcast RSS: https://tripwire.libsyn.com/rss...

When it comes to cybersecurity, industrial IT —consisting mainly of operational technology (OT) and industrial control systems (ICS)—has failed to keep up with development in the enterprise IT world. That’s mostly because industries’ adoption of internet technology has been slower when compared with enterprises. It would take some time to close the gap, but concerted efforts have already been made...

The latest Honeywell USB Threat Report 2020 indicates that the number of threats specifically targeting Operational Technology systems has nearly doubled from 16% to 28%, while the number of threats capable of disrupting those systems rose from 26% to 59% over the same period. Let’s face it. Critical infrastructure operators in manufacturing, aerospace, energy, shipping, chemical, oil and gas...

The trucking sector is essential to countless other industries. Without reliable transportation, supply chains would crumble, and companies and consumers would face shortages. With so much riding on it, it’s no wonder why the industry has fully embraced technology like telematics in recent years. Telematics refers to the suite of technologies fleets use to share data between vehicles and command...

Through the lens of the Florida water supply hack, Dale Peterson teaches how events like these remind us to take the necessary steps to maintain our cybersecurity. Founder and chair of S4 Events, Dale has been helping security professionals effectively and efficiently manage risk to their critical assets for over 15 years. https://open.spotify.com/episode/65nUedFSHvdRSPUHgYH2Qn?si=vd7cA3T7Q4CCh...

In the last quarter of 2019, researchers at ClearSky uncovered an attack operation that they dubbed the “Fox Kitten Campaign.” Iranian actors used this offensive to gain persistent access into the networks of dozens of companies operating in Israel and around the world across the IT, telecommunication, oil and gas, aviation, government and security sectors. These individuals were successful in...

The cyber threat landscape today continues to pose a myriad of unique challenges. This is especially the case for industrial organizations due to factors such as aging equipment, poor design or implementation, skills gaps and a lack of visibility. These shortcomings are exacerbated by the mean time to breach detection, which continues to hover above 150 days on average . The SANS Institute via the...

The digital threat landscape is always changing. This year is an excellent (albeit extreme) example. With the help of Dimensional Research, Tripwire found out that 58% of IT security professionals were more concerned about the security of their employees’ home networks than they were before the outbreak of coronavirus 2019 (COVID-19). Slightly fewer percentages of respondents expressed concerns...
