CMMC CLARIFICATION (Ref CMMC – Appendix B)
No shared system resource such as cache memory, hard disks, registers, or main memory should be able to pass information from one user to another user. In other words, when objects are reused no residual information should exist on that object. This protects the confidentiality of the information. This is typically a feature provided by operating system and software vendors.
