Secure Unidirectional Configurable RS232 Filter and Diode

The FF11N-4 RS-232 configurable filter and isolator diode enforces a unidirectional flow of data. This is an excellent method of protecting critical equipment that is being monitored by another device. The Secure RS-232 Isolator receives an RS-232 command from any connected device and sends it unidirectionally forward to its destination device, ensuring no return signal from the destination to the originating device.

The FF11N-4 RS-232 Configurable Filter uses the same hardware as the FT11N-4, but has the ability to filter the data messages from the sending device through BLACK and WHITE lists that parse the data. The sending device is protected from malicious acts by the optical data diode. The transmitted data from the sending device is protected by the BLACK/WHITE filtration rules programmed into the FF11N-4.

The FF11N-4 is especially suited to protect against data leakage in any scenario where command and monitoring information is sent between two otherwise separated networks. SCADA, System synchronization, control commands, and information sharing can all be done securely via the FF11N-4 Secure RS-232 Isolator.

Features of the FF11N-4 Secure RS-232 Isolator

• Unidirectional by design HW based enforcement of unidirectional data flow by using optical data diode
• Rule-based system Create rules based on regular expressions to enforce which commands and events pass throug
• Flexible configuration Serial communication parameters such as baud rate, parity, etc. are user-configured to fit any architecture
• Transparent The RS-232 Isolator is transparent to the other RS-232 devices in the setup, making it compatible for use in any architecture
