Abstract
A data diode provides a flexible device for collecting data from a data source and transmitting the data to a data destination using one-way data transmission. On-board processing elements allow the data diode to identify automatically the type of connectivity provided to the data diode and configure the data diode to handle the identified type of connectivity. A network tap allows monitoring network traffic on the source side of the data diode.
Claims20
A data diode, comprising:
- a first network interface circuitry, comprising:
- a first processing element;
- a first network connector, coupled to the first processing element;
- and
- a second network interface circuitry, comprising:
- a second processing element;
- and
- a second network connector, coupled to the second processing element;
- a one-way data bridge coupled between the first processing element and the second processing element that allows data flow from the first processing element to the second processing element and physically prohibits data flow from the second processing element to the first processing element;
- and
- a network tap, comprising:
- a first network port;
- a second network port;
- and
- a network switch, configured to mirror network traffic received from the first network port to both the first processing element and the second network port.

A network tap, comprising:
- a one-way data bridge having a first end and a second end that allows data flow from the first end to the second end and physically prohibits data flow from the second end to the first end;
- a first network port;
- a second network port;
- and
- a network switch, configured to mirror network traffic received from the first network port to both the second network port and the first end of the one-way data bridge.
2 more elements
A method of tapping a network, comprising:
- receiving network traffic by a first network port;
- sending the network traffic from the first network port to a network switch;
- mirroring the network traffic by the network switch to both a first processing element of a data diode and a second network port;
- and
- sending the network traffic or information about the network traffic from the first processing element of the data diode to a second processing element of the data diode via a one-way data bridge that physically prohibits data flow from the second processing element to the first processing element.
