SC-3(5): Layered Structures
(Not part of any baseline)
- NIST Special Publication 800-53 Revision 5:
- SC-3(5): Layered Structures
The organization implements 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.
The implementation of layered structures with minimized interactions among security functions and non-looping layers (i.e., lower-layer functions do not depend on higher-layer functions) further enables the isolation of security functions and management of complexity.
