1. A method comprising: receiving, on a hardware computing platform, a dataset from a first Customer Information Control System (CICS) application executing on the hardware computing platform and within a first CICS region, the dataset received from the first CICS application for transmission to a second CICS application in a second CICS region; when the dataset includes channel data, populating a container of the channel data with credential data to authenticate the dataset within the second CICS region; forwarding the dataset to a CICS transformer process of the first CICS region to transform and communicate the dataset to the second application in the second CICS region; receiving the dataset in the second CICS region addressed to the second CICS application; and when the dataset received in the second CICS region includes channel data and the channel data includes a container holding credential data: extracting the credential data from the credential container and authenticate the credential data; removing the credential container from the channel data; and passing the dataset to the second CICS application.
