ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question
Your team is preparing to deliver a new case-management system to a government customer. From the perspective of secure software lifecycle activities, which action best demonstrates validation-that is, evidence that the finished product satisfies documented business requirements before it is released?
Running static application security testing (SAST) on the source code to identify coding flaws.
Executing user acceptance tests with representative business owners using real-world scenarios and success criteria.
Measuring code coverage of automated unit tests during nightly continuous-integration builds.
Performing a peer review of the system's threat model to confirm identified threats are complete and accurate.
Validation focuses on confirming that the completed system meets the user's operational and business needs. Executing user acceptance testing with business owners under realistic scenarios directly shows the product fulfills stated mission objectives. Static analysis, threat-model peer reviews, and code-coverage measurements are important quality or verification practices, but they evaluate how the system was built rather than whether it is the right system for the end user.
