ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

During an architectural risk assessment of a new three-tier web application, you learn that the distributed in-memory cache keeps customer personally identifiable information (PII) in clear text. A stated security requirement mandates encryption of all sensitive data at rest. Which architectural change best ensures compliance with this requirement while maintaining cache performance?

  • Configure the cache to evict entries rapidly by setting a very short time-to-live (TTL) for PII objects.

  • Limit cache access to application servers by tightening network ACLs around the cache cluster.

  • Enable mutual TLS for all traffic between application servers and cache nodes.

  • Encrypt PII in the application before caching it, using keys stored in an HSM (envelope encryption).
