Secure Connectivity via SSL / Kerberos

There are cases where you may want to encrypt data moving between users and applications hosted on IBM System Z (Mainframe). Ericom uses SSL and Kerberos encryption methods (Windows only) to secure such data transfers between clients and servers. For an extensive overview of how SSL works, visit Juniper's site here.

Telnet (Terminal Network) protocol transfers with SSH-secure confidentiality and integrity

When a telnet connection to a server is made, credentials (e.g., username & password) are sent to the server in plain text and a text file containing one's vital security information is available for viewing. As a replacement for Telnet, SSH is used to securely access and execute commands on remote systems and for securely transferring files via encrypted communications. You can learn more about SSH here.

Ericom PowerTerm InterConnect Security Settings Dialogs

SSL Security

In the SSL Security Setup dialog the user will specify the SSL security type. The user may select to accept only certificates that exist in the certificates path or any incoming certificate. The user can also specify to display unknown certificates at connection time and whether to save them.

SSH Security

In the SSH Security dialog the user can specify what type of SSH to use.

Kerberos Security (Windows Only)

In the Kerberos Manager dialog the user can configure advanced Kerberos parameters and perform advanced Kerberos actions.
