Connection security

Most communication between Developer for z/OS® client and host goes through RSE, thus utilizing the connection security provided by z/OS Explorer.

Some Developer for z/OS services use a separate external (client-host) communication path:
  • The Remote Connect Emulator on the client connects to a TN3270 server on the host. The encryption details are controlled by an Application Transparent Transport Layer Security (AT-TLS) policy.
  • Remote (host-based) actions in z/OS UNIX subprojects use an REXEC or SSH server on the host. SSH communication is always encrypted.
