NSE 7 – OT Security 7.2 — Question 10

Which type of attack posed by skilled and malicious users of security level 3 (SL 3) of IEC 62443 is designed to defend against intentional attacks?

Answer options

• A. Unintentional operator error
• B. Access to moderate resources
• C. Low access to resources
• D. Substantial resources

Correct answer: B

Explanation

The correct answer is B because access to moderate resources is designed to mitigate risks from intentional attacks by ensuring that only authorized users can access certain levels of information and capabilities. Options A, C, and D do not specifically address the goal of defending against intentional attacks; A refers to mistakes made by operators, while C and D pertain to resource access levels that do not directly relate to attack prevention.
