A retrospective on the first two decades of control system cyber security – culture issues still prevent successfully securing control systems
A retrospective on the first two decades of control system cyber security – culture issues still prevent successfully securing control systems

It is 2020 yet there has been little movement/understanding on engineering issues and field devices. The irony is that cyber security exists at the network layer where you have short-term glitches, but there is no cyber security where you go “boom in the night” and can have months to years of down time and deaths.…

Why SISEngineer.com?

The world of functional safety can be a confusing place for an end-user.  Industry standards are continually changing, and they are not always clear or consistent.  There are hundreds of vendors and consultants that may or may not be able to offer good products and advice.

Meanwhile, governments and the public grow increasingly intolerant of incidents and near misses.  Traditional approaches to process safety are changing and becoming more sophisticated.

More than ever, it is critical for instrumentation and control systems engineers to have a firm understanding of the theory and practical aspects of process safety and safety instrumented systems.

The SISEngineer site offers unbiased information, tools, and training to prepare today's engineers to become technical leaders and advocates for safety.

If you enjoy this site and are interested in self-driving car safety, please checkout our sister site dedicated to automotive functional safety.
