ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

During an architecture review, you learn that several microservices exchange business transactions through a central message queue. The architect is worried about malicious actors injecting or altering messages in transit. Which design decision most directly mitigates this risk?

  • Place the message broker behind a round-robin network load balancer to hide its IP address.

  • Require each publisher to digitally sign messages and have consumers verify signatures before processing.

  • Store duplicate copies of every message in a secondary queue for later forensic analysis.

  • Configure the queue to operate on plaintext TCP to minimize serialization overhead.
