CCSP Cloud Application Security Practice Question
A company is adopting DevSecOps and wants to incorporate security testing into their continuous integration pipeline. They have decided to run SAST (static analysis) and SCA (software composition analysis) tools. Which of the following is the PRIMARY reason for including SCA in addition to SAST?
⚠ Common exam trap
ISC2 often tests the distinction between SAST (custom code analysis) and SCA (third-party dependency analysis), and the trap here is that candidates may confuse SCA with DAST or think SCA can reduce SAST false positives, when in reality SCA addresses a completely different attack surface—open-source library vulnerabilities.

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
✓
To identify known vulnerabilities in third-party libraries and dependencies
SCA (Software Composition Analysis) is specifically designed to identify known vulnerabilities in third-party libraries and dependencies by comparing their versions against public vulnerability databases like the National Vulnerability Database (NVD) or OWASP Dependency-Check. SAST (Static Application Security Testing) analyzes custom source code for security flaws but cannot inspect external libraries that are often pulled in via package managers (e.g., npm, Maven, pip). Including SCA ensures that the organization addresses supply chain risks, which is a primary goal in DevSecOps pipelines.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To detect insecure runtime behavior
Why it's wrong here
Runtime behavior is detected by DAST or IAST.
- ✓
To identify known vulnerabilities in third-party libraries and dependencies
Why this is correct
SCA specifically scans open source components for known CVEs.
- ✗
To reduce false positives identified by SAST
Why it's wrong here
SCA does not reduce false positives from SAST; they address different things.
- ✗
To scan for vulnerabilities in custom APIs
Why it's wrong here
Custom API vulnerabilities are better found by SAST or DAST.
