ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

During a code review you find that the API gateway plans to cache a user's authorization matrix in server memory for the entire eight-hour session to reduce database look-ups. Which design change would best uphold the complete mediation principle while preserving performance?

  • Continue caching the user's roles in RAM but purge the cache only when the user logs out or after eight hours.

  • Move authorization checks to client-side JavaScript executed after the initial login handshake.

  • Replace the long-lived server-side cache with short-lived, signed access tokens that the gateway must validate on every request.

  • Authorize write requests on each call but allow read-only requests once the session is established.
