Configure/Enable Security Features Overview
You can enable DeviceMaster LT security features the web page (SocketServer or
the NS-Link version). Key and Certificate Management must be done using the
Security tab in the DeviceMaster LT web pages.
If you want secure COM ports, you must also Enable SSL Mode and
enter any
applicable server or client certificates in the NS-Link device driver for Windows.

Description
Enable Secure
Data Mode
If Secur
e Data Mode is enabled TCP connections which carry data
to/from the serial ports will be encrypted using SSL or TLS
security protocols. This includes the following:
• TCP connections to the per-serial-port TCP ports (default
is
8000, 8001, 8002, and so forth) are encrypted using SSL/
TLS.
• TCP connections to TCP Port 4606 on whic
h the
D
eviceMaster LT implements the Comtrol proprietary se
rial
driv
er protocol are encrypted using SSL/TLS.
• Since SSL/TLS can not be used for eith
er UDP data streams
or for
the Comtrol proprietary MAC mode
Ethernet driver
protocol,
both UDP and MAC mode serial data transport
features are disabled.
• In order to minimize possible se
curity problems, e-mail and
RFC1
006 features are also disabled in Secure Data mode.
In addition to encrypting the data streams, it is possible to
configure the DeviceMaster LT so that only authorized client
applications can connect using SSL/TLS. See the Client
Authentication discussion on Page 54 for details.
