CompTIA CySA+ (CS0-002) — Question 421

Which of the following attack techniques has the GREATEST likelihood of quick success against Modbus assets?

Answer options

• A. Remote code execution
• B. Buffer overflow
• C. Unauthenticated commands
• D. Certificate spoofing

Correct answer: C

Explanation

The correct answer is C, as unauthenticated commands can be executed without proper credentials, making them highly effective against Modbus assets. In contrast, remote code execution (A) and buffer overflow (B) typically require more complex conditions to succeed, while certificate spoofing (D) involves more intricate setups that may not guarantee quick results.
