DASTmenetelmiä

DASTmenetelmiä refers to Dynamic Application Security Testing methods. These techniques involve actively probing a running web application to identify vulnerabilities. Unlike Static Application Security Testing (SAST) which analyzes source code, DAST tools interact with the application as an external attacker would, sending various inputs and observing the responses.

DAST tools typically scan for common web vulnerabilities such as SQL injection, cross-site scripting (XSS), broken authentication, and security misconfigurations. They can be automated through scanners or performed manually by security professionals. The advantage of DAST is that it tests the application in its deployed environment, detecting runtime vulnerabilities that might not be apparent from code analysis alone. It can also identify issues related to the application's configuration and infrastructure.

However, DAST has limitations. It generally requires a running application and may not achieve full code coverage, potentially missing vulnerabilities in unexecuted code paths. Furthermore, DAST tools can sometimes produce false positives or false negatives. Despite these limitations, DAST remains a crucial part of a comprehensive application security testing strategy, often used in conjunction with SAST and other security testing methodologies.
