Communication with encryption

HTTPS (HyperText Transfer Protocol Secure) is always used for communication, whereby encryption protocols SSL 3.0 (Secure Sockets Layer) and TLS 1.3 (Transport Layer Security) beneath HTTPS are supported. TLS 1.1 is used for the internal communication with administered AUs.

Automatic redirection to HTTPS takes place for HTTP calls. This applies both for external communication between the administration PC and one of the systems Server Unit, Management Unit or HNC, and also for internal communication of these systems with each other.
