Entry into ICS/OT Cybersecurity

Does anyone know, what is the best practical way to enter ICS/OT Cybersecurity field for a Control system professional ?

I have 20+ experience in hardware and software engineering for DCS, PLC systems but completely new in OT Cybersecurity field.

So, what is the best practical way to do that like the "good training course name", "good certification course" etc. It is purely OT cybersecurity and NOT "IT Cybersecurity"which is very vast.

  • Great question Aji. Asked by many!   Learn. Network. Read. Gain experience. Learn. Attend events. Experiment(safely!). and learn....   

    Tripwire have a good intro page. There are many many others... https://www.tripwire.com/state-of-security/7-top-technical-resource-providers-ics-security-professionals

    Try the OPSec 210 courses - free - you will know the OT stuff so that helps a lot.  https://www.cisa.gov/ics-training-available-through-cisa

    Then there are the ISA and the SANS courses which are amongst the most recognised but not low cost.

    There are many other training providers for lower cost - good search will finds them and look through LinkedIn. 

    Good luck. There are lots of mentors around to help.  We NEED more OT Cyber people.

  • Thanks for the reply. Out of the CISA courses, i have done 2-3 of them like 100W, 301V,401V etc. and will do further progress. ISA and SANS are very costly courses which may cost more than 8000 dollars and it is very difficult. perhaps i will do one foundation module of ISA. was looking for some cheaper options. Thanks once again for prompt reply.

  • Do a course in ISA or IEC62443  usually done as a fundermentals course then you can do the other in any order which are for design, maintenance and risk asessment
