What do data diodes do?

Data Diodes

Data diodes are designed to protect against three things - malware, unauthorised access to information and data leakage. They achieve this through preventing network protocol attacks.

How do Oakdoor data diodes work?

Oakdoor data diodes enforce a hardware-based one-way flow of information, separating inbound and outbound traffic with a protocol break.

Network traffic, such as IP frames, is deconstructed upon entering the input diode, transmitted through its hardware, then reconstructed into IP packets at the output before proceeding further. This ensures that protocol-based attacks are blocked by the diode, protecting against content-based attacks where malicious data attempts to infiltrate.
