AC-04(28) Linear Filter Pipelines

Control

When transferring information between different security domains, implement a linear content filter pipeline that is enforced with discretionary and mandatory access controls.

Discussion

Content filtering is the process of inspecting information as it traverses a cross-domain solution and determines if the information meets a predefined policy. The use of linear content filter pipelines ensures that filter processes are non-bypassable and always invoked. In general, the use of parallel filtering architectures for content filtering of a single data type introduces bypass and non-invocation issues.

Assessment Objective

when transferring information between security domains, a linear content filter pipeline is implemented that is enforced with discretionary and mandatory access controls.

Assessment Method

Examine

Information flow enforcement policy procedures addressing information flow enforcement system design documentation system configuration settings and associated documentation system audit records system security plan other relevant documents or records

Interview

Organizational personnel with information flow enforcement responsibilities system/network administrators organizational personnel with information security responsibilities
