Data diodes (one-way networks) are often used to effect a hardware based 'air-gap' for high security sites. How do they deal with protocols, such as TCP, that require replys? I have some inclination that data diodes installed in both directions with…

I have a software which processes pure numerical data and gives some response. To make it safe, I put it behind two data diodes: one for incoming data, and one for outcoming response. The data diodes are implemented as customer-specific…

I have read data diodes are often used where high security is needed, like in military or critical infrastructures. However, most are UDP based. Modern diodes do support TCP protocol like SMTP, syslogs. However, I have not seen one that says it…

I'm trying to determine the feasibility of using a serial port/cable to act as a simple and cheap data diode. I'll be connecting 2 Windows PCs (1 of which is on a secured network) using a 1-way null modem serial cable. I have physically removed pin…
