ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question
While planning tests for a new web application, the team wants to (1) confirm that the recently added multi-factor authentication (MFA) mechanism actually blocks logons when an incorrect one-time code is entered, and (2) determine how the MFA implementation affects login response time during peak usage. Which categories of security testing should be assigned to activity (1) and activity (2), respectively?
Acceptance testing for (1); functional security testing for (2)
Nonfunctional security testing for (1); functional security testing for (2)
Functional security testing for (1); nonfunctional security testing for (2)
Regression testing for (1); dynamic application security testing (DAST) for (2)
Activity 1 examines whether the security feature (MFA) performs its intended access-control function, so it is a functional security test. Activity 2 evaluates a quality attribute-system performance-rather than a specific security function, so it is a nonfunctional security test. Functional tests focus on the correctness of security logic, whereas nonfunctional tests measure attributes such as performance, reliability, or scalability. Options that reversed the order or substituted acceptance, regression, or DAST do not match the objectives described.
