ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

During security testing of a payment microservice in a staging cluster, you must confirm that the service fails safely if its hardware security module (HSM) suddenly becomes unreachable. Which testing action represents a targeted fault-injection test aimed at exercising this specific failure mode?

  • Intercept the microservice's calls to the HSM and programmatically force each request to time out before a response is returned.

  • Launch a high-volume set of random, malformed TLS handshake messages at the microservice to see how it handles unexpected input.

  • Shut down the microservice's network interface card to observe how it behaves when all outbound traffic is blocked.

  • Perform a static code review to look for unhandled exceptions around every HSM API invocation.
