Why learn it
Why OT and ICS security
Industrial control systems were designed for reliability, not to face hostile networks. Now that they connect to business IT and remote access, an attack can halt production or create a safety hazard. OT security needs people who understand both the controllers and the threats, and ISA/IEC 62443 is the framework the industry uses.

Questions
OT and ICS security: common questions
Do I need a PLC background?
It helps for the PLC hardening course. ICS Security Foundations starts from the basics.
Is IEC 62443 covered?
Yes, in depth in the IEC 62443 course and applied in the PLC, BMS and assessment courses.
How is OT security different from IT security?
Availability and safety come first, and many plant systems cannot be patched or scanned the way office systems are.
Is it free, and is there a certificate?
Every lesson, note and assessment is free. The EDWartens certificate is optional and paid, and it is not an ISA or IEC certification.
