ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

During an architecture review, you discover that an order-processing service will invoke an external payment gateway's REST API over TLS and parse its JSON response to update transaction status. To mitigate security risks introduced by this upstream dependency, which design measure should you add?

  • Allow the gateway to write payment results directly into the backend database to streamline processing.

  • Place the gateway in the same network segment to reduce latency and firewall traversal.

  • Disable mutual TLS and rely on username/password authentication to simplify certificate management.

  • Validate all JSON responses from the gateway against a strict schema before any business logic executes.
