CompTIA CySA+ (CS0-002) — Question 241

Which of the following is the greatest security concern regarding ICS?

Answer options

• A. The involved systems are generally hard to identify.
• B. The systems are configured for automatic updates, leading to device failure.
• C. The systems are oftentimes air gapped, leading to fileless malware attacks.
• D. Issues on the systems cannot be reversed without rebuilding the systems.

Correct answer: D

Explanation

The correct answer, D, highlights that once issues arise in ICS, they often require complete rebuilding to resolve, which is a significant concern for operational continuity. Options A and B are valid concerns but do not pose as severe a risk as the inability to reverse system issues. Option C, while relevant, does not address the fundamental problem of system recovery as effectively as D does.
