Which security testing approach would be MOST effective for detecting cross-site scripting (XSS) vulnerabilities in a web application?
Architecture review
Dynamic Application Security Testing (DAST)
Code review
Vulnerability scanning
The correct answer is Dynamic Application Security Testing (DAST). DAST tools test running applications by simulating attacks, including XSS attempts, and analyzing the application's responses. This approach is particularly effective at finding XSS vulnerabilities because it can identify issues that occur when the application processes and renders input in a browser context.
Code review can help identify XSS vulnerabilities but requires expertise in recognizing vulnerable patterns and understanding all the contexts where output is rendered. It may miss complex or runtime XSS issues.
Vulnerability scanning typically refers to automated tools that check for known vulnerabilities in applications and infrastructure. While useful, general vulnerability scanners may not thoroughly test for all XSS vectors without specific XSS-focused capabilities.
Architecture review examines the high-level design of an application but is unlikely to identify specific implementation issues like XSS vulnerabilities, which occur at the code level rather than the architectural level.
