WGU Courses and Certificates Cybersecurity-Architecture-and-Engineering Question # 58 Topic 6 Discussion

The correct answer is C — Structured Query Language (SQL) injection attacks.

As per WGU Cybersecurity Architecture and Engineering (KFO1 / D488), a Web Application Firewall (WAF) protects web applications by filtering and monitoring HTTP traffic. It isspecifically effective against attacks such as SQL injection, cross-site scripting (XSS), and other application-layer vulnerabilities.

Phishing (A) and social engineering (D) involve human deception, not web application vulnerabilities. Brute force attacks (B) typically target authentication but are not the primary focus of a WAF.

Reference Extract from Study Guide:

"A web application firewall (WAF) detects and prevents attacks against web applications, including SQL injection and cross-site scripting (XSS)."
