SA-08(12) Hierarchical Protection

Control

Implement the security design principle of hierarchical protection in [Assignement: systems or system components].

Discussion

The principle of hierarchical protection states that a component need not be protected from more trustworthy components. In the degenerate case of the most trusted component, it protects itself from all other components. For example, if an operating system kernel is deemed the most trustworthy component in a system, then it protects itself from all untrusted applications it supports, but the applications, conversely, do not need to protect themselves from the kernel. The trustworthiness of users is a consideration for applying the principle of hierarchical protection. A trusted system need not protect itself from an equally trustworthy user, reflecting use of untrusted systems in "system high" environments where users are highly trustworthy and where other protections are put in place to bound and protect the "system high" execution environment.

Assessment Objective

[Assignement: systems or system components] implement the security design principle of hierarchical protection.

Assessment Method

Examine

System and services acquisition policy procedures addressing the security design principle of hierarchical protection used in the specification, design, development, implementation, and modification of the system system design documentation security and privacy requirements and specifications for the system system security and privacy architecture system security plan other relevant documents or records

Interview

Organizational personnel with the responsibility for determining system security and privacy requirements organizational personnel with system specification, design, development, implementation, and modification responsibilities system developers organizational personnel with information security responsibilities
