Security is a key consideration as you set up your thin client environment. By its very nature, in a thin client environment traffic is flowing into and out of your network.
You should consider setting up a firewall to limit access to your data and enforce your organization's access control policy. When you set up a firewall, you'll need to indicate the port number through which the thin client, AcuConnect, and the ACUCOBOL-GT runtime can communicate. The default port number for both the thin client and AcuConnect is 5632.
You can indicate an alternate port number for AcuConnect using the configuration variable, ACURCL_PORT. To indicate a port number for the thin client, set ATC_PORT in the thin client command line file.
If you want to encrypt data before transmitting it across the network, you can use the AGS_SOCKET_ENCRYPT runtime configuration variable on the server. You can also use the ENCRYPTION_SEED variable to initialize an industry-standard 128-bit AES encryption algorithm.
