Entry into ICS/OT Cybersecurity

Question

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 
 Operational Security (OPSEC) for Control Systems (100W) - 1 hour Differences in Deployments of ICS (210W-1) &ndash; 1.5 hours Influence of Common IT Components on ICS (210W-2) &ndash; 1.5 hours Common ICS Components (210W-3) &ndash; 1.5 hours Cybersecurity within IT & ICS Domains (210W-4) &ndash; 1.5 hours Cybersecurity Risk (210W-5) &ndash; 1.5 hours Current Trends (Threat) (210W-6) &ndash; 1.5 hours Current Trends (Vulnerabilities) (210W-7) &ndash; 1.5 hours Determining the Impacts of a Cybersecurity Incident (210W-8) &ndash; 1.5 hours Attack Methodologies in IT & ICS (210W-9) &ndash; 1.5 hours Mapping IT Defense-in-Depth Security Solutions to ICS - Part 1 (210W-10) &ndash; 1.5 hours Mapping IT Defense-in-Depth Security Solutions to ICS - Part 2 (210W-11) &ndash; 1.5 hours Industrial Control Systems Cybersecurity Landscape for Managers (FRE2115) - 1 hour 
 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.
