The answer is static application security testing (SAST). This is the correct choice because SAST analyzes source code, bytecode, or binaries without executing the application, making it ideal for early vulnerability detection during the coding phase of the SSDLC. By automating static analysis in the CI/CD pipeline, developers catch flaws like SQL injection or buffer overflows before the code is built or deployed, directly supporting the 'shift left' principle where issues are cheapest to fix. On the Certified Cloud Security Professional CCSP exam, this question tests your understanding of when to apply SAST versus DAST in the secure software development lifecycle; a common trap is confusing SAST with DAST, which requires a running application and finds vulnerabilities later in testing. Remember the mnemonic: SAST scans source, DAST detects dynamic—SAST comes first in the SSDLC timeline.
CCSP Cloud Application Security Practice Question
This CCSP practice question tests your understanding of cloud application security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is implementing a secure software development lifecycle (SSDLC) for its cloud-native applications. Which practice should be automated to detect vulnerabilities early in the development process?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Static application security testing (SAST)
Static application security testing (SAST) analyzes source code, bytecode, or binaries without executing the application, making it ideal for early detection of vulnerabilities during the coding phase of the SSDLC. By integrating SAST into the CI/CD pipeline, developers receive immediate feedback on security flaws such as SQL injection or buffer overflows, enabling remediation before the code is built or deployed. This aligns with the 'shift left' principle, catching issues when they are cheapest and easiest to fix.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Static application security testing (SAST)
Why this is correct
SAST scans source code early in development, enabling early vulnerability detection.
Related concept
Read the scenario before looking for a memorised answer.
✗
Penetration testing in production
Why it's wrong here
Penetration testing is typically performed later and is not automated in early stages.
✗
Dynamic application security testing (DAST)
Why it's wrong here
DAST is performed on running applications, which is later in the lifecycle.
✗
Manual code review
Why it's wrong here
Manual code review is not automated, though it can catch issues.
Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the distinction between SAST (white-box, early) and DAST (black-box, late), and the trap here is that candidates mistakenly choose DAST because they confuse 'dynamic' with 'automated,' forgetting that DAST requires a running application and cannot detect vulnerabilities in source code.
Detailed technical explanation
How to think about this question
SAST tools parse the application's abstract syntax tree (AST) and perform data flow analysis to trace untrusted input through sinks like SQL queries or system calls, flagging potential injection flaws without executing the code. In cloud-native environments with microservices, SAST must be configured to handle polyglot codebases (e.g., Java, Python, Go) and containerized build pipelines, often using tools like SonarQube or Checkmarx integrated via Jenkins or GitLab CI. A real-world scenario: a developer commits a change that introduces a cross-site scripting (XSS) vulnerability in a React component; SAST catches it in the pull request, preventing the insecure code from reaching the container image registry.

→Watch for words such as best, first, most likely and least administrative effort.

Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
