I’m confused about the levels. I thought Level 2 was more about basic threats, but I can't recall if hackers are specifically targeting that one.

I practiced a question like this, and I feel like Level 4 was mentioned as the highest risk. Could it be that one?

I'm a bit confused on the IEC 62443 security levels. Is level 4 the highest or the lowest? I want to make sure I don't get this backwards. Maybe I should review the standard quickly before answering.

Okay, let me see if I can reason this out. Cybercriminals and hackers would likely be going after the most valuable or sensitive systems, so that points to the highest security level, which is 4. I'll go with A.

Hmm, I'm a bit unsure about this one. I know the IEC 62443 standards have different security levels, but I can't remember which one is specifically for cybercrime targets. I'll have to think this through carefully.
