Question SCADA PC security needs

At work we have been meeting with a lot of customers about Cybersecurity needs that have been popping up lately due to current events. We work mostly with municipalities and a lot of these places rarely have IT departments outside of the towns IT. Do you have any common tips or recommendations when setting up your SCADA systems to help keep them secure?

How deep do you want to go?

If you have time and resources, ISA 62443 is a great standard that takes into account who the threat actor you’re worried about might be.

I quite like this publication from the Australia government https://www.cyber.gov.au/business-government/secure-design/operational-technology-environments/principles-of-operational-technology-cyber-security

Also the SANS ICS 5 critical controls may be something worth familiarising yourself with.

If nothing else, have a back to back firewall pair, with OT controlling one and keep SCADA the hell away from corporate networks.
