ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

A development team is planning security tests for an industrial IoT gateway that will operate in harsh field conditions. You are asked to design a test that will determine the exact load level at which the device's embedded web service stops responding, so the team can document that failure point and add safeguards. Which approach BEST satisfies the goal of break testing for this component?

  • Use a hardware debugger to flip individual bits in RAM and verify the watchdog handler resets the device correctly.

  • Perform a dynamic application security (DAST) scan against the live service to check for OWASP Top 10 vulnerabilities.

  • Run the full unit-test suite with code-coverage instrumentation to ensure at least 90 percent branch coverage is achieved.

  • Progressively increase concurrent HTTP sessions against the web service until it stops responding and record the threshold.
