Data Diode

Data diodes provide unidirectional network communication to securely transfer data from high-security environments, ensuring critical infrastructure and industrial control systems are protected from inbound cyber threats.

Disabled

When this checkbox is selected, the data diode functionality is disabled.

Producer

When this checkbox is enabled, it allows the Guardian to send data out to the data diode and the upstream Central Management Console (CMC).

When Producer is enabled, the fields below show.

Protocol (communication protocol to be used)
Token (of the upstream CMC)
Host (address of the data diode)
Username (for the data diode)
Password (for the data diode)
Directory (the location on the data diode to store the data)

This enables one-way data transfer to the data-diode and the upstream CMC system.
