What Are the Benefits of Adopting the Cloud in Industrial Cybersecurity?

Cloud adoption has come a long way from its early days where corporate executives questioned the stewardship of their data. The initial suspicions of “where’s my data” have been laid to rest, as administrative tools and contractual obligations have emerged to give better visibility to, and accountability of, data custodianship. Even the capabilities...

ICS Security: What It Is and Why It's a Challenge for Organizations

Industrial control systems (ICS) are specific kinds of assets and associated instrumentation that help to oversee industrial processes. According to the National Institute of Standards and Technology, there are three common types of ICS. These are supervisory control and data acquisition (SCADA) systems, which help organizations to control dispersed...

Revisiting the Relevance of the Industrial DMZ (iDMZ)

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...

Partnerships – The Key to Navigating the Industrial Security Landscape

The events of 2020 helped to accelerate the convergence between information technology (IT) and operational technology (OT) for many organizations. As reported by Help Net Security, for instance, two-thirds of IT and OT security professionals said in a 2020 survey that their IT and OT networks had become more interconnected in the wake of the pandemic. More than three-quarters of respondents went...

The Next Disruptive ICS Attacker: Only Time Will Tell

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...

The Next Disruptive ICS Attacker: An Advanced Persistent Threat (APT)?

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...

The Next Disruptive ICS Attacker: A Ransomware Gang?

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...

The Next Disruptive ICS Attacker: A Disgruntled Insider?

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...
