The Owl Multi-level Data Retrieval Service (MDRS) is a comprehensive hardware & software solution that provides a seamless NFS proxy service across a dual-path transfer platform. The Owl MDRS enables analysts to quickly and seamlessly access files in other security domains without having to wait for data requisitions to be completed. Analysts are able to “browse down” to lower security levels or in some cases, “browse up”, to access files housed at higher security levels, in the cloud or in other domains, or retrieve portions of very large files.
Using patented Owl technology, MDRS modifies the traditional two-way communication path used by NFS and enables two discrete, single direction paths (request & response) in a single Owl Cross Domain Solution (OCDS/ECDS) implementation. Each path passes through a distinct and isolated data diode, which protects the integrity of each network while allowing files to be transferred. MDRS maintains secure and isolated domains while requesting and accessing files through a transparent and secure implementation of the Network File Sharing (NFS) protocol. Cross domain security is maintained with a hardened RHEL operating system and strictly defined role-based access controls (RBAC).
