PROVIDING SECURE DATA TRANSFER BETWEEN NETWORKS

摘要

A data frame transmitted over a serial link between a destination network and a source network is received by a computer-implemented system in the destination network. The data frame is compatible with a data link layer protocol and includes a data field. The computer-implemented system in the destination network converts the data frame directly into a format compatible with an application layer protocol, where converting the data frame into the format comprises interpreting received information included in the data field as numerical values rather than executable code. The computer-implemented system in the destination network outputs the numerical values to an application in the destination network.

1. A computer-implemented method, comprising:
receiving, by a computer-implemented system in a destination network, a data frame transmitted over a serial link between the destination network and a source network, the data frame compatible with a data link layer protocol, the data frame including a data field; converting, by the computer-implemented system in the destination network, the data frame directly into a format compatible with an application layer protocol, wherein converting the data frame into the format comprises interpreting received information included in the data field as numerical values rather than executable code; and outputting, by the computer-implemented system in the destination network, the numerical values to an application in the destination network.
