Summary

The system must not store sensitive information in temporary files or cache memory.

Description

Applications sometimes reside in or get consumed by environments in which caching is possible. Caching helps performance or makes certain actions more comfortable for the application users. However, cached information is often more susceptible to being exposed or corrupted. Thus, avoiding cache memory and temporary files helps protect sensitive information.
