Hard to chew. Probably not worth the jaw work.
Summary
The article discusses the challenge of extracting operational data from air-gapped networks while maintaining security. It describes a solution involving creating a custom data diode using Raspberry Pi and opto-couplers to safely extract syslog information from isolated networks used in critical infrastructure, finance, and healthcare sectors.
Key quotes
· 4 pulledAir-gapped networks are physically isolated computer networks that do not connect to the internet or other external networks.
By design, these networks prevent remote access and reduce the risk of cyber attacks.
How do you safely extract operational data for monitoring or analysis without compromising security?
Learn how we developed a data diode using Raspberry Pi and opto couplers to extract syslog information from air-gapped networks.
