Filter Sidecar Protocol (FSP) Specification

Abstract: The purpose of this document is to describe the cross domain solution (CDS) Filter Sidecar Protocol (FSP). A filter sidecar is generally considered to be a network connected system, usually on a trusted operating system, that provides high assurance content inspection and sanitization functions for Cross Domain Solutions. The Filter Sidecar Protocol is intended to provide a mechanism for making new filtering capabilities available to an existing cross domain solution by adding a certified sidecar platform. As long as the CDS is tested to properly implement the Filter Sidecar Protocol, users should be able to add new content types without having to completely recertify the CDS since the filter sidecar would be separately certified.
