Assessment Objective

Determine if:

• AC-04(32)(a) when transferring information between different security domains, the process that transfers information between filter pipelines does not filter message content;
• AC-04(32)(b) when transferring information between different security domains, the process that transfers information between filter pipelines validates filtering metadata;
• AC-04(32)(c) when transferring information between different security domains, the process that transfers information between filter pipelines ensures that the content with the filtering metadata has successfully completed filtering;
• AC-04(32)(d) when transferring information between different security domains, the process that transfers information between filter pipelines transfers the content to the destination filter pipeline.
