- Air-gapped networks are physically isolated to enhance security but pose challenges for data extraction.
- A bespoke data diode solution using Raspberry Pi devices and opto couplers was implemented for one-way data transfer.
- The setup includes a 'send' Pi on the air-gapped network and a 'receive' Pi on the external monitoring network.
- Custom scripts ensure reliable, albeit slower, data transmission to maintain security and integrity.
- UART over serial ports was chosen for its reliability and simplicity in one-way communication.
- The solution allows secure extraction of syslog and performance data without compromising the air gap.
- Nelop Systems offers tailored solutions with over 25 years of experience in IT and systems integration.
- UK-based and on-site services ensure operational continuity and minimal downtime for critical systems.
