Cisco Certified Support Technician (CCST) CybersecurityVulnerability ManagementMedium
A security team has deployed a new web application firewall (WAF) to protect a critical online service. The team wants to ensure that the WAF is effectively blocking known attack patterns and preventing common web-based vulnerabilities before the service goes live. Which type of vulnerability assessment would be most appropriate for this scenario?
- AHost-based vulnerability scan
- BExternal penetration test
- CWeb application vulnerability scan
- DInternal vulnerability scan
Show answer & explanationAnswer & explanation
Correct answer: C. Web application vulnerability scan
A web application vulnerability scan specifically targets web applications, identifying flaws like SQL injection, cross-site scripting, and other common web-based attack vectors that a WAF is designed to protect against. This allows the team to validate the WAF's effectiveness.
Why the other options are wrong
- A. A host-based scan focuses on the underlying operating system and services of a server, not the application layer vulnerabilities of a web application.
- B. While a penetration test could include web applications, a dedicated web application scan is more focused on identifying specific web-based vulnerabilities and is often a precursor or complement to a penetration test.
- D. An internal scan focuses on internal network devices and services, not specifically web application logic.
Web Application Vulnerability Scan
An automated assessment that identifies security weaknesses in web applications by simulating attacks like SQL injection, XSS, and broken authentication.
- Targets application layer vulnerabilities.
- Often uses dynamic application security testing (DAST) tools.
- Helps validate WAF effectiveness.
