Which of the IEC 62443 security levels is identified by a hacktivist/terrorist target?

Answer options

• A. 1
• B. 3
• C. 4
• D. 2

Correct answer: B

Explanation

IEC 62443 security level 3 is designated for environments that require a higher degree of protection against targeted attacks, such as those from hacktivists or terrorists. The other levels (1, 2, and 4) do not specifically address the same level of threat or are focused on different aspects of security.
