SC-03(05) Layered Structures

Control

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.

Discussion

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) enables the isolation of security functions and the management of complexity.

Assessment Objective

security functions are implemented 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.

Assessment Method

Examine

System and communications protection policy procedures addressing security function isolation system design documentation system configuration settings and associated documentation system audit records system security plan other relevant documents or records

Interview

System/network administrators organizational personnel with information security responsibilities
