nections.

2 = medium
3 = high
4 = any (automatic negotiation)
WARNING
Current browsers do not support
cipher suites from the Low level. If
you use Low with a current
browser and the setting HTTPS
only for access to the utnserver
Control Center ( 66), a connec-
tion cannot be established.
Use an encryption level as high as
possible.
Description
Defines the connection type (HTTP/HTTPS) to
be used for connecting to the utnserver Control
Center.
on = HTTP/HTTPS
off = HTTPS only
The encryption strength is defined via the
encryption protocol and level  64.
WARNING
Current browsers do not support
low security settings. With them a
connection cannot be established.
Do not use the following combina-
tion: Encryption protocol HTTPS
and encryption level Low.
When the connection is estab-
lished, the identity of the UTN
server is verified. For that, the client asks for the
certificate via the browser ( 70). This certifi-
cate must be accepted by the browser; read the
documentation of your browser software.
