ServSwitch CX Uno IP is built from the ground-up to be secure. It employs a
sophisticated 128bit public/private key system that has been rigorously analysed
and found to be highly secure (a security white paper is available upon request
from Black Box). Therefore, you can position the ServSwitch CX Uno IP alongside
the firewall and control hosts that are also IP connected within the local
network.
IMPORTANT: If you make the ServSwitch CX Uno IP accessible from the public
Internet, care should be taken to ensure that the maximum security available
is activated. You are strongly advised to enable encryption and use a strong
password. Security may be further improved by restricting client IP addresses,
using a non-standard port number for access.
Ensuring sufficient security
The security capabilities offered by the ServSwitch CX Uno IP are only truly
effective when they are correctly used. An open or weak password or
unencrypted link can cause security loopholes and opportunities for potential
intruders. For network links in general and direct Internet connections in
particular, you should carefully consider and implement the following:
• Ensure that encryption is enabled.
By local configuration menu or global configuration page.
• Ensure that you have selected secure passwords with at least 8 characters
and a mixture of upper and lower case and numeric characters.
By global configuration page.
• Reserve the admin password for administration use only and use a non-
admin user profile for day-to-day access.
• Use the latest Secure VNC viewer (this has more in-built security than is
available with the Java viewer). To download the viewer.
• Use non-standard port numbers.
• Restrict the range of IP addresses that are allowed to access the ServSwitch
CX Uno IP to only those that you will need to use. To restrict IP access.
• Do NOT Force VNC protocol 3.3.
• Ensure that the computer accessing the ServSwitch CX Uno IP is clean of
viruses and spyware and has up-to-date firewall and anti-virus software
loaded that is appropriately configured.
• Avoid accessing the ServSwitch CX Uno IP from public computers.
Security can be further improved by using the following suggestions:
• Place the ServSwitch CX Uno IP behind a firewall and use the port numbers
to route the VNC network traffic to an internal IP address.
• Review the activity log from time to time to check for unauthorized use.
• Lock your server consoles after they have been used.
A security white paper that gives further details is available upon request from
Black Box.
Ports
In this configuration there should be no constraints on the port numbers
because the ServSwitch CX Uno IP will probably be the only device at that IP
address. Therefore, maintain the HTTP port as 80 and the VNC port as 5900.
Addressing
When the ServSwitch CX Uno IP is situated alongside the firewall, it will require
a public static IP address (i.e. one provided by your Internet service provider).
