ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

During a peer review of a C++ service, you notice several threads insert and delete entries in a shared std::map that is declared in global scope. Intermittent crashes and corrupted data have been reported in production. Which change will most effectively eliminate the race condition while keeping the code logic intact?

  • Recompile the code with maximum optimization flags (e.g., -O3) to streamline memory access.

  • Configure the runtime to spawn more worker threads so contention is less likely.

  • Increase the capacity of the map to reduce hash collisions and improve performance.

  • Guard all map insert, erase, and lookup operations with a mutex or similar lock.
