With the appearance of malware and nation state attacks on Industrial Control Systems (ICS), such as the Stuxnet (2010), Industroyer (2016) and TRITON (2017) attacks, the IEC 62433 standards are gaining wider attention.
While the potential targets to attack in an ICS system are many-fold, one plant asset that…
The exposure of industrial facilities to cybersecurity threats has never been higher. An analysis performed by IBM security found that the number of attacks on SCADA systems increased 636% from 2012 to 2014, with 675,816 cybersecurity incidents in January 20141. Finding an effective method for evaluating the current level…

Industrial Automation Control Systems (IACS) Cybersecurity based on IEC 62443 was created to be compatible with agile development methodology. The standard deliberately talks about processes and not phases, such as those in the waterfall model. The processes defined can be met simultaneously and are, most likely, already being followed…
By now we’ve all become familiar with safety integrity levels (SIL), as they have become part of our everyday lives. However, with the recent release of several cybersecurity standards in the IEC 62443 series, things are getting more complicated. This series of standards introduces two more levels…
Isn’t it frustrating when you experience an event that disrupts operations and then discover it could have been prevented? Very often a detailed analysis will reveal that a combination of (preventable) mistakes and unknown factors caused the incident. Training can help the mistakes, but dealing with the unknowns is a little…
Information Technology (IT) is the personnel, hardware, and software that controls non-physical devices and/or processes such as websites, financial data, personal information, etc.
Operation Technology (OT) is the personnel, hardware, and software that controls physical devices and/or processes such as manufacturing, oil & gas, power, etc. Today, OT has many…
