Abstract :
The style of networked file sharing that dominates modern workstations can provide a flexible and highly secure connection between networks operating at different security levels. We illustrate this by describing a highly secure multilevel file server under development as part of the Secure Network Server (SNS) Development Program. The file service, constructed with the Network File Service (NFS) protocol, would provide a trusted building block supporting low to high data transfers by existing applications hosted on commercial off the shelf (COTS) workstations. The facility will be hosted on a high assurance platform, the LOCK Trusted Computing Base, providing strong separation between security levels
