ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

During threat modeling, your team identifies that the order-processing microservice depends on an external OAuth token validator. To satisfy the fail secure design principle, how should the microservice behave if the validator becomes unreachable at run time?

  • Queue the requests and complete them after connectivity is restored, skipping a second token check.

  • Reject every incoming request until the validator is reachable again, returning an authorization failure.

  • Accept requests that present tokens found in a five-minute cache while logging a warning.

  • Temporarily bypass authentication but record detailed audit logs for later review.
