Which of the IEC 62443 Security Levels is identified by a cybercrime/hacker target?

Answer options

• A. 4
• B. 3
• C. 1
• D. 2

Correct answer: B

Explanation

Security Level 3 (SL3) in IEC 62443 indicates that the system is targeted by cybercriminals, requiring robust security measures. In contrast, Levels 1, 2, and 4 pertain to less severe threats or different operational contexts, thus are not identified by a hacker target.
