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

Security
Option
Description
Enable Secure
Data Mode
If
Secure 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 which the
DeviceMaster LT implements the Comtrol proprietary serial
driver protocol are encrypted using SSL/TLS.
•
Since SSL/TLS can not be used for either 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 security problems, e-mail and
RFC1006 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
discussion on Page 54 for details.
