CISA Practice Question: Is developing a web application using an Agile…
An organization is developing a web application using an Agile methodology. The security team wants to integrate security testing early in the development lifecycle. Which of the following is the BEST approach to achieve this?
⚠ Common exam trap
It's easy for candidates to confuse 'early testing' with any security test performed during development, but only SAST in the CI pipeline provides automated, continuous analysis at the code level before builds are deployed.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement static application security testing (SAST) in the continuous integration pipeline
Integrating SAST into the CI pipeline allows automated scanning of source code for vulnerabilities (e.g., SQL injection, XSS) as code is committed, aligning with Agile's iterative development. This shift-left approach catches flaws early, reducing remediation cost and effort compared to later stages.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Implement static application security testing (SAST) in the continuous integration pipeline
Why this is correct
SAST scans source code and can be integrated into CI to find vulnerabilities early.
- ✗
Conduct a penetration test after each sprint
Why it's wrong here
While a penetration test after each sprint can identify vulnerabilities in a completed increment, it violates the Agile principle of integrating security testing *early* in the lifecycle, as the test occurs only after development is finished for that sprint. This approach is tempting because periodic penetration tests are a standard compliance requirement for production releases, and would be correct in a waterfall model where security validation gates a final deployment.
- ✗
Schedule an annual vulnerability scan of the production environment
Why it's wrong here
This is too late and not integrated into development.
- ✗
Perform dynamic application security testing (DAST) on deployed builds
Why it's wrong here
DAST requires a running application, so it is not early in development.
