The operating system must implement security functions as a layered structure minimizing interactions between layers of the design and avoiding any dependence by lower layers on the functionality or correctness of higher layers.

RHEL-06-000419-PNF	RHEL-06-000419-PNF	RHEL-06-000419-PNF_rule		Medium

Description
The operating system isolates security functions from non-security functions by means of an isolation boundary (implemented via partitions and domains) controlling access to and protecting the integrity of the hardware, software, and firmware that perform those security functions. The information system maintains a separate execution domain (e.g., address space) for each executing process.
