Questions
Cybersecurity: common questions
Is this offensive security?
No. It is defence: architecture, standards, detection, risk and response.
Where should I start?
Cybersecurity Fundamentals if you are new to the field. Engineers who work with PLCs, SCADA or building systems can go straight to the OT courses, which are written for them.
Is OT cybersecurity a job for network engineers or automation engineers?
Both, and the shortage is on the automation side: people who know what a PLC does and can read IEC 62443.
