# SC-3(1) — Hardware Separation

- **Control ID:** SC-3(1)
- **Family:** [SC](/md/families/SC.md)
- **Baselines:** No content available.
- **Enhancement of:** [SC-3](/md/controls/SC-3.md)

## Description

Employ hardware separation mechanisms to implement security function isolation.

## Discussion

Hardware separation mechanisms include hardware ring architectures that are implemented within microprocessors and hardware-enforced address segmentation used to support logically distinct storage objects with separate attributes (i.e., readable, writeable).
