Secure connections
Using Transport Layer Security (TLS), Z and I Emulator for Web extends secure host data access across intranets, extranets, and the Internet. Mobile workers access a secure Web site, receive authentication and establish communication with a secure enterprise host. With client and server certificate support, Z and I Emulator for Web can present a digital certificate to the Telnet server - such as IBM Communications Server for z/OS - for authentication.
Z and I Emulator for Web can also be configured for use in environments that include firewalls. Firewall ports need to be opened for the functions defined in your Z and I Emulator for Web session definitions. For more information, refer to Using Z and I Emulator for Web with a firewall.
