Blog Entry: IEC 61508 – Two Key Fundamental Concepts
We want our system to work. We're going to do everything we can to make it work properly. If it doesn't work, we want it to fail in a predictable and hopefully safe manner. If the failure modes are predictable, we can design the equipment to be fail safe. That's…

Blog Entry: Creating a Cyber Hygiene Plan
One of the things that automation companies are beginning to do is to plan for cyber hygiene. More and more companies are implementing automation specific awareness training for their employees. They conduct periodic exercises which like sending phishing emails to see who if you respond. They might leave USB devices…
Recorded Webinars: Using exSILentia Cyber for Cybersecurity Risk Assessments
A risk-based approach is key for effectively managing cybersecurity for Industrial Control Systems (ICS). It helps to identify critical areas requiring mitigation and focus limited resources on the most critical issues. The ISA/IEC 62443-3-2 standard provides the formal process for conducting these risk assessments in a two-staged approach (initial and detailed). Over the years as exida completed many cybersecurity risk assessments, it became clear that a tool which could efficiently record and export the results of the study was critical to the successful completion of the assessments. To meet this need, the exSILentia Cyber tool was developed as a new set of modules on the exSILentia v4 platform. In this webinar we will demonstrate how the exSILentia cyber tool can be used to improve the effectiveness of the cybersecurity risk assessment process and streamline the reporting process.
Blog Entry: Automation Cybersecurity - Myths vs. Reality
In today’s automation systems environment, certain myths continue to persist. For example, “cyber attacks are only a concern for big companies”. Although it may be less likely to be targeted by, say, a nation state attack, we’ve seen that malware can cause a shutdown of a system or trigger a…
News Item: exida Authored Article Appears in AiCHE Process Safety Progress Publication
How extreme failure-data filtering leads to poor process safety This paper describes both appropriate and inappropriate practices of filtering field failure data (FFD) prior to using the resulting failure count from the failure data to estimate failure rates. The underlying causes of inappropriate (extreme) filtering of FFD are examined, and…

Blog Entry: Why is Cybersecurity Hygiene Important for Automation Systems?
Cybersecurity incidents have shown that there can be major consequences for automation systems. There have been incidences where attackers have been able to manipulate the human resource interface console directly. It was only by chance that an operator in one particular instance happened to notice that his mouse pointer was…
Blog Entry: Automation Cybersecurity: IT vs OT - Differing Priorities
Before you can dive in and look at the core concept of automation cybersecurity , it's helpful to first define it. Automation cybersecurity is the prevention of intentional or unintentional interference with proper operation of automation systems including industrial controls, smart manufacturing, and IIOT systems through the use of computers,…

Recorded Webinars: Should my Initial Cybersecurity Risk Assessment Consider Non-hackable Protections?
The initial cybersecurity risk assessment (or high-level risk assessment as it was previously called) is an important step in the cybersecurity lifecycle. It is at this point that the basis for network segmentation and creating zones and conduits for an industrial control system (ICS) starts. At this stage the “worst case unmitigated cyber security risk” for any scenario is documented to allow assets to be grouped into areas of similar risks. Several methodologies have been adopted to complete this task, and two of the most common are asset-based and PHA-based, each with a slightly different focus and approach. One common question that we receive when conducting initial risk assessments, is if any protections can be credited. At this stage no cybersecurity protections can be credited, but what about non-hackable safety protections? In this webinar we will review similarities and differences between these two approaches to initial risk assessment and answer the question of whether or not we can look at non-hackable protections during the initial risk assessment.
White Paper: Improving Mechanical Component Reliability with Partial Valve Stroke Testing
This paper describes how failure rates of mechanical devices will change depending on how frequently they move in operation. The phenomenon involved has been defined as Static Friction (Stiction). Stiction is described along with its impact and the primary method of prevention, Partial Valve Stroke Testing (PVST).
