The Fox DataDiodes software standard supports the Common Internet File System (CIFS) used by e.g. Windows to share file over a network. CIFS is also know as Server Message Block (SMB).
The solution is transparent for users, since they push files from the BLACK network just as if they where directly connecting to the RED side. The Fox DataDiode software supports NTLMv2 for authentication. The solution supports files but also (sub)-folders. Multiple parallel CIFS shares are allowed. Users can be limited by the administrator in having access to specific shares and group of shares. The throughput of CIFS is 100Mbit/s.
