CompTIA CySA+ (CS0-003) — Question 287

Several incidents have occurred with a legacy web application that has had little development work completed. Which of the following is the most likely cause of the incidents?

Answer options

• A. Misconfigured web application firewall
• B. Data integrity failure
• C. Outdated libraries
• D. Insufficient logging

Correct answer: C

Explanation

The correct answer is C, as outdated libraries can lead to vulnerabilities and incompatibilities, which are common in legacy applications. Options A and D may contribute to security issues, but they are less likely causes for incidents compared to outdated libraries. Option B, while a concern, does not directly relate to the development status of the application.
