Data Transmission Across Air Gap¶
For scenarios with strict isolation requirements, air gaps are usually used as network isolators for security isolation between the networks of different security levels. For example, in the power sector, high-to-low and low-to-high air gaps are deployed between Security Zone I and Security Zone III.
Even if high-to-low or low-to-high air gap is deployed, EnOS Edge can still achieve data communication and file transfers between different security zones by transmitting data across the air gap, providing data exchange services for the deployed applications while conforming to on-site security regulations.
Using the power sector as an example, the data transmission across air gap supported by EnOS can be divided as per the below.
High-to-low: Supports transferring data and files of the device collection points from Security Zone I and Security Zone II to Security Zone III.
Low-to-high: Supports transferring text files in E language from Security Zone III to Security Zone I and Security Zone II.
Specific air gaps are required for EnOS Edge’s data transmission capability. For details, see the link below.
